Reason behind the bad web design is the selection of an inexperienced website design company. A good web design and website development company takes care of things that turn a website design bad. Some of the common mistakes that lead to useless website design, but taken care of by an expert website design.

Distracting Backgrounds-
Backgrounds are meant the professional backdrop to a website that can attract the online users and involve them. A bad website design has background that distracts or displeases the visitors and makes the text difficult to read. Moreover, the images used a backgrounds make the websites difficult to load.

Inappropriate Text Style-
For the visitors, the information displayed on a website is the best medium to know about it. A badly designed website has font too small or too big to read out. Underlines and bolded paragraphs and use of italics too frequently too make the website design bad.

Use of Animations-
Animations are not meant to be used excessively in a website design. These blinking text and animations often steal the efficacy of a website. And an expert web design company makes less use of such features so that a website has professional look and feel.

Interrupting Music-
Most disastrous aspects of a website design is the ‘Background Music’. The automatic music played in loops and on every web page is definitely a part of the bad web design. It reduces the interest of online users in your website.

No HTML Validation-
HTML validation is an important thing to do with a website design. It needs proper validation as without it, your website has fewer chances to get indexed in the search engine results. Moreover, such websites have slow loading pages.

Here, the HTML helper was “wrapping” the FluentHtml library from MvcContrib to produce the following html output (given an IEnumerable list containing the items “Foo” and “Bar”):

   1:  <div>

   2:      <input id="Name_Foo" name="Name" type="radio" value="Foo" /><label for="Name
_Foo" id="Name_Foo_Label">Foo</label>

   3:      <input id="Name_Bar" name="Name" type="radio" value="Bar" /><label for="Name
_Bar" id="Name_Bar_Label">Bar</label>

   4:  </div>

MVC 2 has released, providing an editor template that can be used as it rely on metadata, which allow us to customize the views appropriately.  For example, for the radio buttons above, we want the “id” attribute to be differentiated and unique and we want the “name” attribute to be the same across radio buttons so the buttons will be grouped together and so model binding will work appropriately. We also want the “for” attribute in the <label> element being set to correctly point to the id of the corresponding radio button.

The default behavior of the RadioButtonFor() method that comes OOTB with MVC produces the same value for the “id” and “name” attributes so this isn’t exactly what I want out the box if I’m trying to produce the HTML mark up above.

If we use an EditorTemplate, the first gotcha that we run into is that, by default, the templates just work on your view model’s property. But in this case, we *also* was the list of items to populate all the radio buttons. It turns out that the EditorFor() methods do give you a way to pass in additional data. There is an overload of the EditorFor() method where the last parameter allows you to pass an anonymous object for “extra” data that you can use in your view – it gets put on the view data dictionary:

   1:  <%: Html.EditorFor(m => m.Name, "RadioButtonList", new { selectList = new SelectList(new[]
{ "Foo", "Bar" }) })%>

Now we can create a file called RadioButtonList.ascx that looks like this:

   1:  <%@ Control Inherits="System.Web.Mvc.ViewUserControl" %>

   2:  <%

   3:      var list = this.ViewData["selectList"] as SelectList;

   4:  %>

   5:  <div>

   6:      <% foreach (var item in list) {

   7:             var radioId = ViewData.TemplateInfo.GetFullHtmlFieldId(item.Value);

   8:             var checkedAttr = item.Selected ? "checked=\"checked\"" : string.Empty;

   9:      %>

  10:          <input type="radio" id="<%: radioId %>" name="<%: ViewData.TemplateInfo.HtmlFieldPrefix
%>" value="<%: item.Value %>" <%: checkedAttr %>/>

  11:          <label for="<%: radioId %>"><%: item.Text %></label>

  12:      <% } %>

  13:  </div>

IN the above code, there are several things that to be noted. First, you can see in line #3, it’s getting the SelectList out of the view data dictionary. Then on line #7 it uses the GetFullHtmlFieldId() method from the TemplateInfo class to ensure to get unique IDs. We pass the Value to this method so that it will produce IDs like “Name_Foo” and “Name_Bar” rather than just “Name” which is our property name. However, for the “name” attribute (on line #10) we can just use the normal HtmlFieldPrefix property so that we ensure all radio buttons have the same name which corresponds to the view model’s property name. We also get to leverage the fact the a SelectListItem has a Boolean Selected property so we can set the checkedAttr variable on line #8 and use it on line #10. Finally, it’s trivial to set the correct “for” attribute for the <label> on line #11 since we already produced that value.

Because the TemplateInfo class provides all the metadata for our view, we’re able to produce this view that is widely re-usable across our application. In fact, we can create a couple HTML helpers to better encapsulate this call and make it more user friendly:

   1:  public static MvcHtmlString RadioButtonList<TModel, TProperty>(this HtmlHelper<TModel>
htmlHelper, Expression<Func<TModel, TProperty>> expression, params string[] items)

   2:  {

   3:      return htmlHelper.RadioButtonList(expression, new SelectList(items));

   4:  }

   5:

   6:  public static MvcHtmlString RadioButtonList<TModel, TProperty>(this HtmlHelper<TModel>
htmlHelper, Expression<Func<TModel, TProperty>> expression, IEnumerable<SelectListItem> items)

   7:  {

   8:      var func = expression.Compile();

   9:      var result = func(htmlHelper.ViewData.Model);

  10:      var list = new SelectList(items, "Value", "Text", result);

  11:      return htmlHelper.EditorFor(expression, "RadioButtonList", new { selectList = list });

  12:  }

This allows us to simply the call like this:

   1:  <%: Html.RadioButtonList(m => m.Name, "Foo", "Bar" ) %>

In that example, the values for the radio button are hard-coded and being passed in directly. But if you had a view model that contained a property for the collection of items you could call the second overload like this:

   1:  <%: Html.RadioButtonList(m => m.Name, Model.FooBarList ) %>

The Editor templates introduced in MVC 2 definitely allow for much more flexible views/editors than previously available.

In order to get past the corruption issues in a Windows XP system is by executing CHKDSK/F command. This command checks the physical and logical integrity of the file system and repairs it in case of any damage.

Though the command, in most of the situations, is a life-saver, but do not guarantee 100% success in every life system corruption issue. In such cases, when the CHKDSK command fails to repair, an ideal alternative is to reinstall Windows XP and restore data from an updated backup. However, in case no backup is available, the user can easily recover data using a commercial Windows Recovery application.

Let’s consider a practical scenario that explains the above situation. You encounter the below error message at the startup of Windows XP operating system:

“C:\$MFT is corrupt and unreadable. Please run the chkdsk utility.”

After the above boot error message pops up, your system becomes unbootable and its data gets inaccessible. As suggested in the error message, when you run CHKDSK utility, you encounter another error message:

In the master file table (MFT) bitmap, CHKDSK discovered free space marked as allocated. CHKDSK discovered free space marked as allocated in the volume bitmap. Windows found problems with the file system. Run CHKDSK with the /F (fix) option to correct these.

As error message suggest, when you execute CHKDSK utility with ‘/F’ parameter, it shows the same error message. Since the system could not be started, the data saved in the Windows based hard drive remains inaccessible.

Resolution: In order to overcome the CHKDSK/F failure error message, follow the step mention below:

1. Reinstall Windows XP on your system.
2. Restore the data from an updated backup. In case no backup is available, use a commercial Windows Data Recovery utility.

Such windows data recovery tools use effective recovery techniques to perform complete recovery of all formatted files and folders.

Thus, one can easily analyze the file system corruption. And In worst cases, you might need to reformat the entire hard drive partitions and seek the help of Partition http://www.all1tunes.comRecovery tools, especially when no data backup is available.

Let’s check out the problem, which can occur when trying to set up or repair Microsoft Office on a Windows hard disk. Specifically, when you attempt to repair or install Microsoft Office 2002 (XP), Microsoft Office 2003 or Microsoft Office 2007, the setup may exit silently without notifying or displaying any error message on screen. For say, when you try to install or repair Office, it prompts you to specify the Product Identification key, but exits unexpectedly.

For typical Office setup failure, you can examine the associated log file, which is created by Office Setup in \Temp folder in .txt format. This file might contain one of the below or similar log entries with different module and function:

Exception code: C0000006 IN_PAGE_ERROR Module: C:\WINDOWS\System32\msi.dll Function: 0×7642452f

Or

Exception code: C0000006 IN_PAGE_ERROR Module: C:\WINDOWS\system32\IMAGEHLP.dll Function: 0×76c94afa

The depicted problem, as mentioned, is generally the result of file system damage or hard disk problems. Thus, to resolve the problem, consider implementing the solutions mentioned underneath:

‘Analyze’ and then ‘Defragment’ the hard disk using Disk Defragmenter tool. To do so, you must have administrative rights to access the partition/volume.

Repair the disk using Autochk.exe, Chkdsk.exe,, and Chkntfs.exe tools. If the problem persists, reformat the hard disk and restore the deleted data from backup. Use a Partition Recovery Software than any kind of backup issues.

Use of a Partition Recovery utility allows to scan the logically crashed hard disk and restore the lost/deleted partitions in just few simple steps.

Using HTML_QuickForm2 helps these developers create usable and secure Web forms without sacrificing visual appeal. This solution takes much of the guesswork out of secure forms development, allowing you to create robust forms with minimal time investment.

It will show you how to take advantage of HTML_QuickForm2 to streamline the creation and validation of complex HTML forms.

Installing HTML_QuickForm2

HTML_QuickForm 2 is a PEAR package, meaning you can install it using the PEAR package installer. Presuming you’re using the original installer, execute the following command to install HTML_QuickForm2:

%>pear install –onlyreqdeps HTML_QuickForm2-alpha

When installed, you can begin programmatically creating your forms.

Creating a Form with HTML_QuickForm2

HTML_QuickForm2 is the second incarnation of the aptly-named HTML_QuickForm, rewritten from the ground up to take advantage of the object-oriented (OO) features in PHP 5. Therefore, if you’re not familiar with the OO development approach, it will take some time to get acquainted with the syntax because forms are created using a rigorous class structure.

Let’s see these examples that hopefully will help elucidate how you can use HTML_QuickForm2 is to create increasingly complex forms.

Figure-1:

Figure 1. Creating a Simple Form with HTML_QuickForm2

The form in Figure 1 can be created using approximately 25 lines of code, as shown below.

<?php
 require_once "HTML/QuickForm2.php";
 require_once 'HTML/QuickForm2/Renderer.php';
 $format = array(
 ''     => 'Newsletter Format:',
 'text' => 'Text',
 'html' => 'HTML'
 );
 $form = new HTML_QuickForm2('newsletter');
 $name = $form->addText('name')->setLabel('Your Name:');
 $email = $form->addText('email')->setLabel('Your E-mail Address:');
 $newsletter = $form->addSelect('format', null, array('options' => $format));
 $newsletter->setLabel('Preferred Newsletter Format:');
 $form->addElement('submit', null, 'Submit!');
 $renderer = HTML_QuickForm2_Renderer::factory('default');
 echo $form->render($renderer);
?>

HTML_QuickForm2 offers a series of methods, which are responsible for creating form controls such as text fields (addText())and select boxes (addSelect()). Each of these controls is accompanied by control labels that can be added using the setLabel() method. Finally, HTML_QuickForm2 gives you the flexibility to render forms using a wide variety of approaches, including using the Smarty templating engine and an HTML_QuickForm2_Renderer object.

You can just use the default renderer as demonstrated here, passing that object to the render() method in order to output the form. Next, let’s consider the slightly more complex example depicted in Figure 2.

Figure 2. Creating a More Complex Form Variation

This time, the fieldset tag has been used to create a slightly more organized form structure. Because the form elements appear inside the fieldset boundary, you need to create these elements using the methods exposed through the fieldset object! Neglecting to do so will cause form elements to be rendered outside of the boundary. The following listing creates the form presented in Figure 2.

<?php
require_once “HTML/QuickForm2.php”;
require_once ‘HTML/QuickForm2/Renderer.php’;
$format = array(
” => ‘Newsletter Format:’,
‘text’ => ‘Text’,
‘html’ => ‘HTML’
);
$form = new HTML_QuickForm2(’newsletter’);
$fieldSet = $form->addFieldset()->setLabel(’Subscribe to the Newsletter!’);
$name = $fieldSet->addText(’name’)->setLabel(’Your Name:’);
$email = $fieldSet->addText(’email’)->setLabel(’Your E-mail Address:’);
$newsletter = $fieldSet->addSelect(’format’, null, array(’options’ => $format));
$newsletter->setLabel(’Preferred Newsletter Format:’);

$fieldSet->addElement(’submit’, null, ‘Submit!’);
$renderer = HTML_QuickForm2_Renderer::factory(’default’);
echo $form->render($renderer);
?>

Try experimenting with creating form controls using the HTML_QuickForm2 object instead of the FieldSet object in order to observe the effects of control location placement.

Validating the Form

The previous two examples demonstrated how easy it is to create and render forms using HTML_QuickForm2, but they did nothing to inspect and validate user input — not to mention informing users when the form wasn’t successfully completed. You can configure control-specific validation requirements using theaddRule() method, as shown here: $name = $form->addText(’name’)->setLabel(’Your Name:’); $name->addRule(’required’, ‘Please provide your name.’); After having added similar requirements to the other form controls, HTML_QuickForm2 will automatically adjust the rendered form to inform the user of the required fields, as depicted in Figure 3.

Figure 3. Adding Field Requirements

The required rule is just one of several supported by HTML_QuickForm2. Among others, you can control input lengths, compare the input with some predefined value, and even create your own custom rules using a callback. Consult the HTML_QuickForm2 documentation for the complete details. Even with the rules added, HTML_QuickForm2 will not actually validate the input until you explicitly call the HTML_QuickForm2 object’svalidate() method. Therefore, you’ll need to add the following code somewhere before the form is rendered:

if ($form->validate()) {
 echo "<p>SUCCESS!</p>";
}

Of course, in a real-world situation you’ll want to carry out more than just a simple notification; you likely will add the subscriber’s information to a database. However, if the user’s input does not meet the validation requirements, HTML_QuickForm2 will notify the user of the problem, as depicted in Figure 4.

Figure 4. Displaying Error Messages

You can easily add CSS to the form, thereby making the error messages quite evident.

HTML_QuickForm2 provides developers with the means for rigorously creating and validating forms in a manner that greatly reduces the likelihood of invalid or harmful input while simultaneously reducing the amount of time and effort needed to develop complex form layouts.

In order to overcome such error messages, the database administrator needs to run an inbuilt repair utility named ‘DBCC CHECKDB’. While this command is competent enough to repair a damaged SQL Server 2000 database, it might also result in loss of data from the database. To prevent any such data loss situation from occurring, you will need to repair the database by using a powerful MDF Database Repair application.

Lets consider a real-time scenario where you encounter a severity level 16 error message while trying to mount your SQL Server 2000 database:

“Table error: Object ID O_ID, index ID I_ID, page P_ID, row ROW_ID. Record check (CHECK_TEXT) failed. Values are VALUE1 and VALUE2.”

Once the above error message flashes on the screen, the database records become inaccessible.

Reason:

Two main reasons liable for the occurrence of 2537 error message are discussed underneath:

• A condition specified in the CHECK_TEXT statement could not be fulfilled.
• The database table is logically or physically damaged.

Tips to Resolve:

To get past the above error message, an easy way is to restore the database from an updated backup. However, if in case backup is not available, and then repair the database using following steps:

• In case the SQL Server 2000 database table is physically damaged, and then replace the physically damaged component with a new component. To determine the component that is physically damaged, check the system logs.
• In case the SQL Server 2000 database table is logically corrupted, then run DBCC CHECKDB command with a suitable repair clause. While doing so, the logical corruption can be resolved, but it might also result in loss of data. To ignore such data loss situations, it is advisable to repair the database using a commercial MDF Repair application. Such MDF File Repair tools are totally non-destructive and keep the original file untouched while repairing.

Consider, you have accidentally run fsck on a mounted Linux OS. The inode root gets damaged and all inodes start calling similar blocks. When you try to mount the volume after fsck, the following error message is discovered:

“Mount: wrong fs type, bad option, bad superblock on /dev/hda1, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

When you run \dmesg\, as suggested in the error message, another error message may be displayed, that is:

“ext3-fs: corrupt root inode, run e2fsck”

And when you run e2fsck, yet another error message is displayed, that is:

“Root inode is not a directory. Clear?”

Once you press ‘Y’ and proceed with the process, the parent entry of each inode from the root directory will be deleted. The root inode will attempt to recover but if it fails, another error message will be displayed, that is:

“Cannot Allocate Root Inode”

After this error message, you will not be able to access your system.

Reason: This behavior is caused due to corruption of the file system, superblock, root inode, or any other Linux data structure. Because of this, the OS cannot locate the hard disk volumes.

Solution:

In order to sort out this problem and perform Linux data recovery, you should reformat the hard disk and reinstall the Linux operating system. However, that would invariably mean that your valuable data will be lost.

In such cases, you should use a third-party Linux recovery to recover lost data. Such tools are able to Recover Linux data safely by using fast yet sophisticated scanning algorithms.

It’s the case with most of the applications it too can face some errors that may lead to data corruption. The data corruption cases may arise because of various issues such as power surges, virus infections, human errors, abrupt shutdown when the database is open, etc. In such cases, you should replace the database with an updated backup. And if the backup is not updated and you need the data urgently, then you should use an SQL MDF repair tool that will help you to repair SQL database.

Let’s consider a scenario wherein you have got MS SQL Server installed on your system, and one day when you open the SQL Server database, it fails to open. An error message is displayed.

“Server can’t find the requested database table.”

Once you encounter this error message, you are unable to access the database.

Cause: Here the error is that the SQL database is corrupt and, thus, inaccessible. It may have got corrupt because of various reasons such as virus infections, human errors, power surges, abrupt system shutdown when the database is open, etc.

Resolution: If the SQL database is not a complex one and there isn’t huge amount of data, then you should try and rebuild the database. However, if the database is complex and contains huge amount of data, then you should consider using a third-party sql server repair application for mdf repair. Such tools are read-only in nature and do not overwrite the data while scanning the databases using fast yet sophisticated algorithms. Also, these tools have rich interface and enable you to repair the database yourself without the intervention of an expert.

SQL Recovery software is an MS SQL repair tool that is able to repair SQL databases created in MS SQL Server 2000, 2005, 2008. It can recover all kinds of database components such as tables, defaults, stored procedures, triggers, views and rules.

In addition, it can recover database constraints such as primary key, foreign key, unique key, and check. In addition to all this, it can repair a database even if it is not repairable by the DBCC CHECKDB command. This tool is compatible with Windows 7, Vista, 2003 Server, XP, 2000, and NT.

If any of these database objects or the entire database gets damaged, you can not access your valuable data from it. In such circumstances, Oracle Database Recovery software is required to extract data from the database.

In order to overcome DBF corruption, Oracle offers a number of methods to detect and repair data files. These options include:

DBVerify- It is an external command-line utility, which enables you to validate offline data files of Oracle database. In addition to the offline data files, you can also use this utility for checking validity of the backup data files.

ANALYZE … VALIDATE STRUCTURE- It is used to verify every single data block in the analyzed object. If this tool finds any corruption, rows are added to INVALID_ROWS table.

DB_BLOCK_CHECKING- If DB_BLOCK_CHECKING argument is set as TRUE, Oracle carries out a walk-through of the data in database block for checking whether it’s self-consistent or not. This block checking process may add 1 to 10% overhead to server. This setting is recommended only if you can accept the overhead.

DBMS_REPAIR- It enables you to find and fix database corruption. This process needs two administration Oracle database tables for holding the list of damaged blocks and the index keys which point to those damaged blocks.

The first phase checks the consistency of the allocation structures in disk space, the second phase checks the integrity of all pages and their structures, and the last phase checks the catalog consistency.

If critical errors are found in any of the phases, the DBCC CHECKDB command terminates immediately. This happens when the SQL Server database is badly corrupted, and is beyond the repairing capabilities of DBCC CHECKDB command. In such cases, if you need to access the database records, then you will need to restore the database records from a valid backup. But, if no backup is available or backup falls short to restore the required amount of data, then you will need to repair the database by using advanced MS SQL Server Recovery application.

Let’s consider a practical scenario, where you receive the below error message when you attempt to access one of your table records-

Table error: Object ID O_ID1, index ID I_ID1 cross-object chain linkage. Page P_ID1 points to P_ID2 in object IDO_ID2, index ID I_ID2.

The above error message primarily results in inaccessibility of all the table records. Additionally, the error message pops up every time you attempt to access the table records.

Cause: Reason of error

The above table error message occurs when the next page pointer of P_ID1 page points to different object. This can happen either due to logical corruption factors or physical crash of a system component.

Resolution: Steps to be used to resolve the above error message

Database table corruption, if caused due to physical damage, can be resolved by changing the damaged system component. For logical table corruption reasons, run DBCC CHECKDB command with appropriate repair clause.

While the physical corruption issues can be resolved easily changing the system component, the probability of logical corruption problems being resolved by DBCC CHECKDB command is slightly less. In such cases, you will need to use advanced Recovery application to repair the database table. A SQL Repair software can be easily downloaded from Internet.

What You Need-

To create your own Facebook application, you should know how to program in one of the supported languages, such as PHP, Ruby on Rails, or Python. With that knowledge, all you need to do to get started is:
1. Add Facebook Developer Application to your Facebook account.
Go to the Facebook Developers page and click “Add developer.” This is the central location for all your applications on Facebook. You can request as many as 100 API keys from the applications page, as well as manage and change the settings for all your applications. Now that you have added Facebook Developer Application to your account, let’s move on to adding your very first application.

2. Add your first Facebook application.
Go back to the Facebook Developers page and click the Set Up New Application button. This will take you to the “Create Application” page, where you are required to provide the name of your application and, as a rule, agree to certain terms and conditions.
After saving changes to this page, you will be taken to your application’s homepage, which serves as your application’s edit page. You can change all the settings related to your application here, such as its name, description, icon, logo and much more. You can add more developers if you are going to develop the application in a team.
On the same page, Facebook provides you with an API Key and a Secret Key, which are the passports for your application to interact with

Facebook core applications and the outside world. Do not share you secret key with anyone.

Pre-development Changes

To start developing your application, you need to make important changes to the following settings:

• API Key – This unique key helps Facebook identify whatever request(s) you make. Enclose this API key along with all your requests.
• Secret Key – As mentioned previously, you should keep this key safe and share it with no one, because it is responsible for authenticating your request.

Now, click on the Authentication tab, where you need to specify:

• Post-Authorize Callback URL – When a user authorizes your application and adds it to a Facebook account, then Facebook pings this URL. So, this URL needs to be your site’s URL where you application is hosted. This cannot be a URL from Facebook.
• Post-Authorize Remove URL – When your application is removed by a user, this URL will be pinged along with a post request, which will contain the User_id. This process allows you to log which user has removed your application.

Now click on the canvas tab, where you need to specify:

• Canvas Page URL – Choose a canvas page URL for Facebook, such as http://apps.facebook.com/your-app-name.
• Canvas Callback URL – This is the muscle of your application. Facebook pulls the content from this URL and displays it on the application’s canvas page. The URL can be where you have your application hosted.
• Render Method – You need to selected this option according to your code. If your code is going to have FBML tags, then you should select “FBML” in this option. Otherwise, leave it default as “iframe” (for this example, you can choose either).

These settings should be enough to get you started with your first Facebook application. Undoubtedly, you can make many other changes to suit your needs in due course.

Now that you have set up the application, let’s have a look-see at how to put some muscle on your bare-bones application. In this example, you need to use Facebook’s PHP client library, which is a compressed file. After downloading the client library, extract the files. You will get two folders namely, footprints and php.

Footprints is a sample application provided to help you understand how the Facebook API works. However, because the API functions keep changing, this code might have some deprecated functions. The php folder contains the library files that you will use to talk back to the Facebook API.

Create a file called index.php and copy the following code into it:

<?php

 require_once 'php/facebook.php';

 $appapikey = 'INPUT YOUR APP KEY HERE';

$appsecret = 'INPUT YOUR APP SECRET KEY HERE';

 //create the object

$facebook = new Facebook($appapikey, $appsecret);

 /**

 * Check if we have an already logged in user ?

 * Yes - Skip the require_login

 * No - User is redirected to facebook login page

 */

if(!is_numeric($facebook->get_loggedin_user()) || !$facebook->api_client->users_hasAppPermission("publish_stream"))

  $facebook->require_login($required_permissions = 'publish_stream');

 /**

 * In case user reaches here and our application doesn't have proper permissions to publish,

 * then display this error message

 */

 if(!$facebook->api_client->users_hasAppPermission("publish_stream"))

{

  echo 'Darn !! Something just broke !!' ;

}

 /**

 * Check if we have Post data and a status to update

 */

if($_POST['update_me'] == 1)

{

    $res=$facebook->api_client->stream_publish($_POST['st'],'');

  $uid = $facebook->get_loggedin_user();

   $tmp = explode ("_",$res);

  if($uid == $tmp[0])

  {

    echo "Timeline updated successfully, <a href='http://www.facebook.com/?id=$uid'> Go back to your profile page</a>";

  }

  else

  {

    echo "Couldn't update your status, Please try again";

  }

}

/**

 * Display the form to update status

 */

else

{

  ?>

<form method="POST" action="http://www.your_domain.com/index.php" >

  <input value="1"/>

  <textarea></textarea> <br>

  <input value="Update status" />

 </form>

  <?php

}

?>

Make sure you complete the following tasks to properly build your application:

1. Include the library file (facebook.php) and change the path in require_once to match your folder hierarchy.
2. Copy/paste the API key and secret key before trying to use your application. It won’t work without these anyhow.
3. Input the canvas page URL right to the path of the script on your server/domain.

When you execute the above script, it will look for logged in users, if any. If a user is not logged in, then it redirects the user to the Facebook login page. This is also handled by the require_login function, but the problem with require_login is that it redirects so often that any post data to your page is lost. So, you have put a check before calling the require_login function. In the same line, you also check whether or not your application has permission to post updates onto a user’s stream. If you do not have permission, the user is prompted to allow your application.

When you have permissions and post data, the status is updated to the user. When a status is successfully posted, a response of the typeuserid_postid is returned. If it fails, then different error codes are returned. Find a list of error codes on Facebook’s wiki page.

You can extend the above code to suit your requirements. If you feel confident, you can move on to write some advanced programs using FBJS and XFBML. Other than that, you should keep abreast of any functions that Facebook deprecates — particularly those that your code might be using. Otherwise, your application might crash all of a sudden.

Database remains unmountable in most cases after it is corrupted, further rendering to inaccessibility of all its records. In such situations, if the administrator wants to access the Oracle database records, then he/she will need to use a cold backup to restore the database. However, if the administrator has not created any backup or the backup is not sufficient to meet all his/her requirements, then he/she needs to use an advanced third-party Oracle Recovery utility to repair the database.

Let’s consider a practical case, where you, as a database administrator, perform below steps:

1.You copy your database file when your database is alive.
2. Then you update the table stored in the data file.
3. After this, you shutdown the database using ’shutdown immediate’ command and change the datafile with its ‘alive’ copy.

After this, when you try to mount your Oracle database, it does not mount. The reason is-

The fundamental reason for unmountability of the database is corruption in datafile. To prevent the corruption of datafile, you should never follow the above steps sequentially.

Resolution:

It is advisable to restore the database from a standby database in order to resolve datafile corruption and to mount your Oracle database. However, if no such database exists, then you will need to repair the database. To effectively do so, you will need to search for a commercial dbf recovery application that can repair your corrupted database.

A repair tool to recover Oracle database and to bring it back to a reusable state can be easily downloaded from the Internet. Such tools can Recover Oracle Database after any logical corruption scenario using powerful recovery algorithms. Moreover, these tools do not make any change in the original database, making them completely non-destructive in nature.

For most of the Oracle database administrators, Oracle Recovery Software is a utility that they use to recover Oracle database after all kinds of logical crashes. The tool supports recovery of Oracle 9i databases. Designed for Windows XP and 2003, the read only software leaves the original database untouched and unmodified.

Public Function Remove(ByVal str As String) As String
        Remove = str

At the highest level, JSF technology provides an API for creating, managing, and handling UI components and a tag library for using components within a web page. The JSF 2.0 release simplifies the web developer’s life by providing the following:

• Reusable UI components for easy authoring of web pages
• Well defined and simple transfer of application data to and from the UI
• Easy state management across server requests
• Simplified event handling model
• Easy creation of custom UI components

For GET requests and Ajax integration, we need to drill down into JSF 2.0’s support, as well as the productive features that this support makes possible. The demo application is an online quiz that allows a registered user to answer five simple questions that test his or her general knowledge. Towards the end of the quiz, the application displays the score.

Using GET Requests in JSF 2.0

To support GET requests, JSF 2.0 introduced the concept of View Parameters. View Parameters provide a way to attach query parameters to URLs. You use the tag <f:viewParam> to specify the query parameters.

Take this code for example:

<f:metadata>

<f:viewParam name=”previousScore” value=”#{recordBean.oldScore}” />

</f:metadata>

In this example, the value of the parameter previousScore will be automatically picked up and pushed into the property oldScore of the recordBean. So, when a request like this comes for a URL:

displayData.jspx?previousScore=10

The value of the bean property oldScore will be set to 10 when the request is processed, which avoids manually setting the value or using a listener. Another interesting point to notice is that like any other component the tag <f:viewParam> supports conversion and validation. Hence, there is no need for separate conversion/validation logic.

The new tags in JSF 2.0 related to support for the GETrequest.

h:button :- Renders a button that generates a GET request without any handcoding of URLs

h:link :- Renders a link that generates a GET request without any handcoding of URLs

h:outputStylesheet :- Refers to a CSS resource

h:outputScript :- Refers to a JavaScript resource

f:event :- Registers a specification-defined or a user-defined event

f:ajax :- Enables associated component(s) to make Ajax calls

f:metadata :- Declares the metadata facet for this view

f:viewParam :- Used in to define a view parameter that associates a request parameter to a model property

f:validateBean :- Delegates the validation of the local value to the Bean Validation API

f:validateRegex :- Uses the pattern attribute to validate the wrapping component

f:validateRequired :- Ensures the presence of a value

Bookmarking Support

Because all JSF 1.x interactions with the server use only HTTP POST requests, those JSF versions don’t support bookmarking pages in a web application. Even though some tags supported the construction of URLs, it was a manual process with no support for dynamic URL generation. JSF 2.0’s support for HTTP GET requests provides the bookmarking capability with the help of new renderer kits.

A new UI component UIOutcomeTarget provides properties that you can use to produce a hyperlink at render time. The component allows bookmarking pages for a button or a link.

The two HTML tags that support bookmarking are h:link and h:button. Both generate URLs based on the outcome property of the component, so that the author of the page no longer has to hard code the destination URL. These components use the JSF navigation model to decide the appropriate destination.

Take the following code for example:

<h:link outcome=”login” value=”LoginPage” >

<f:param name=”Login” value=”#{loginBean.uname }” />

</h:link>

This bookmarking feature provides an option for pre-emptive navigation (i.e., the navigation is decided at the render response time before the user has activated the component). This pre-emptive navigation is used to convert the logical outcome of the tag into a physical destination. At render time, the navigation system is consulted to map the outcome to a target view ID, which is then transparently converted into the destination URL. This frees the page author from having to worry about manual URL construction.

Support for Ajax

The default implementation provides a single JavaScript resource that has the resource identifier jsf.js. This resource is required for Ajax, and it must be available under the javax.faces library. The annotation@ResourceDependency is used to specify the Ajax resource for the components, the JavaScript function jsf.ajax.request is used to send information to the server in an asynchronous way, and the JavaScript function jsf.ajax.response is used for sending the information back from the server to the client.

On the client side, the API jsf.ajax.request is used to issue an Ajax request. When the response has to be rendered back to the client, the callback previously provided by jsf.ajax.request is invoked. This automatically updates the client-side DOM to reflect the newly rendered markup.

The two ways to send an Ajax request by registering an event callback function are:

• Use the JavaScript function jsf.ajax.request
• Use the <f:ajax> tag

JavaScript Function jsf.ajax.request

The function jsf.ajax.request(source, event, options) is used to send an asynchronous Ajax request to the server. The code snippet below shows how you can use this function:

<commandButton id=”newButton” value=”submit”

onclick=”jsf.ajax.request(this,event,

{execute:’newButton’,render:’status’,onevent: handleEvent,onerror: handleError});return false;”/>

</commandButton/>

The first argument in the function represents the DOM element that made an Ajax call, while the second argument (which is optional) corresponds to the DOM event that triggered this request. The third argument is composed of a set of parameters, which is sent mainly to control the client/server processing. The available options are execute, render, onevent, onerror, and params.

<f:ajax> Tag

JSF 2.0 enables page authoring with <f:ajax>, which is a declarative approach for making Ajax requests. You can use this tag instead of manually coding the JavaScript for Ajax request calls. This tag serves two roles, depending on the placement. You can nest it within any HTML component or custom component. If you nest it with a single component, it will associate an Ajax action with that component.

The <f:ajax> tag has four important attributes:

• render – ID or a space-delimited list of component identifiers that will be updated as a result of the Ajax call
• execute – ID or a space-delimited list of component identifiers that should be executed on the server
• event – The type of event the Ajax action will apply to (refers to a JavaScript event without the on prefix)
• onevent – The JavaScript function to handle the event

Consider the following code from the login page of the online quiz application. The code validates the input of the email field by sending an Ajax call for every keystroke. The validation is done by a managed bean method that acts as a value change listener.

<h:inputText label=”eMail ID”   id=”emailId” value=”#{userBean.email}” size=”20″

required=”true” valueChangeListener=”#{userBean.validateEmail}”>

<f:ajax event=”keyup” render=”emailResult”/>

</h:inputText>

…

<h:outputText id=” emailResult” value=”#{userBean.emailPrompt}” />

Using Ajax to Validate the Input: The online quiz application validates email field input by sending an Ajax call for every keystroke.

Here, <f:ajax> is nested within the emailId inputText component. For every keyup event that is generated, an Ajax call is sent to the server, which invokes the valueChangeListener. By default, the component in which the tag is nested is executed on the server. So, the execute attribute is not specified. Also, for an input component, the default event is valueChange, so the event attribute is also not used. The render attribute indicates that the outputText component emailResult should be updated after the Ajax call.

If you place this tag around a group of components, it will associate an Ajax action with all the components that support the events attribute.

<f:ajax event=”mouseover”>

<h:inputText id=”input1″ …/>

<h:commandLink id=”link1″ …/>

</f:ajax>

In this example, input1 and link1 will exhibit Ajax behavior on a mouseover event.

<f:ajax event=”mouseover”>

<h:inputText id=”input1″ …>

<f:ajax event=”keyup”/>

</h:inputText>

<h:commandLink id=”link1″ …/>

</f:ajax>

In this example, input1 and link1 exhibit Ajax behavior on keyup and mouseover events, respectively.

Using the Ajax tag enhances the markup of the associated component to include a script that triggers the Ajax request. This the page author to issue Ajax requests without having to write any JavaScript code.

These new features enable developers to build truly dynamic web pages simply and easily.

Here’s the JavaMail code for sending the email:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import java.io.*;

class EmailClient
{
    final String emailInfo = "EmailInfo.properties";
    Properties properties = new Properties();

    public static void main(String args[])
    {
        EmailClient emailClient = new EmailClient ();
        emailClient.sendEmail();
    }

    private void sendEmail()
    {
       try{
            //This is required to load all the properties
           FileInputStream fileInputStream = new FileInputStream(emailInfo);
           properties.load(fileInputStream);
           fileInputStream.close();
        }catch(IOException ioe)
       {
            //throw IOException of your choice.
            //can end here
       }
        System.out.println("Email properties read successfully.");

       String smtpAddress = properties.getProperty("smtpAddress");
       String fromAddress = properties.getProperty("fromAddress");
       String toAddress = properties.getProperty("toAddress");
       String emailSubject = properties.getProperty("emailSubject");
       String emailBody = properties.getProperty("emailBody");

       Properties props = new Properties();
        props.put("mail.smtp.host", smtpAddress);
        props.put("mail.from", fromAddress);
       Session session = Session.getInstance(props, null);

       try
       {
           MimeMessage mimeMessage = new MimeMessage(session);
           mimeMessage.setRecipients(Message.RecipientType.TO,toAddress);
           mimeMessage.setSentDate(new Date());
           mimeMessage.setSubject(emailSubject);
           mimeMessage.setText(emailBody);
           System.out.println("Sending e-mail...");
           Transport.send(mimeMessage);
           System.out.println("e-mail sent.");
       }
        catch(MessagingException me)
       {
           System.out.println("e-mail send failed.");
           me.getMessage();
       }
    }
}

The code is fairly simple to understand:

• The properties have been loaded for the email to be sent from a properties file. This could come from any other source, such as hardcoded values, a database, a user interface, etc.
• The processed information is updated to the MimeMessage object, which is the actual email object. (The MIME, or Multipurpose Internet Mail Extensions, is an Internet standard that specifies how messages must be formatted for interoperability.)
• MimeMessage takes a session argument, which can either be created or refer to the default session.
• The session—important in any context and used here for the email—is established using the properties mail.smtp.host and mail.from.
• Other details such as the date, subject, and the body of the email, which will be used when the email is sent, are being set out.
• Finally, the email is dispatched using the send() method of the Transport class.
• The entire email information is made available in a properties file. Here are the contents of the properties file for this application:

smtpAddress=smtp.server.address
fromAddress=myself@me.com
toAddress=someone@you.com
emailSubject=First email
emailBody=My first email

It’s stated previously that the source of the required information can vary, so we can modify the entries at will without recompiling the code to experiment. By the way, holding configurable information in properties files is a standard programming practice.

It seems to be simple right, and now let’s add more advanced features to the application. Don’t you think, you need attachments with email? The following code creates that-

import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import java.util.*;
import java.io.*;

class SendAdvancedEmail
{
    final String emailInfo = "EmailInfo.properties";
    Properties properties = new Properties();

    public static void main(String args[])
    {
        SendAdvancedEmail sendAdvancedEmail = new SendAdvancedEmail ();
        sendAdvancedEmail.sendEmail();
    }

    private void sendEmail()
    {
       try{
            //This is required to load all the properties
           FileInputStream fileInputStream = new FileInputStream(emailInfo);
           properties.load(fileInputStream);
           fileInputStream.close();
        }catch(IOException ioe)
       {
            //throw IOException of your choice.
            //can end here
       }
        System.out.println("Email properties read successfully.");

       String smtpAddress = properties.getProperty("smtpAddress");
       String fromAddress = properties.getProperty("fromAddress");
       String toAddress = properties.getProperty("toAddress");
       String emailSubject = properties.getProperty("emailSubject");
       String emailBody = properties.getProperty("emailBody");

       Properties props = new Properties();
        props.put("mail.smtp.host", smtpAddress);
        props.put("mail.from", fromAddress);
       Session session = Session.getInstance(props, null);

       try
       {
           MimeMessage mimeMessage = new MimeMessage(session);
           mimeMessage.setRecipients(Message.RecipientType.TO,toAddress);
           mimeMessage.setSentDate(new Date());
           mimeMessage.setSubject(emailSubject);
            //The following is required to add attachments
           MimeMultipart multipart = new MimeMultipart();
           //Creating the text part of the email message
           BodyPart bodyPart = new MimeBodyPart();
            //The type is set to "text/plain"
           bodyPart.setText(emailBody);
           //Creating the attachment part of the email message
           BodyPart attachment = new MimeBodyPart();
           DataSource source = new FileDataSource(emailInfo);
           attachment.setDataHandler(new DataHandler(source));
           attachment.setFileName(emailInfo);
           //attachment.setContent(properties, "text/html");
            //Now combining the email message and the attachment
           multipart.addBodyPart(bodyPart);
           multipart.addBodyPart(attachment);
           //Setting the message with the multipart just created
           mimeMessage.setContent(multipart);

           System.out.println("Sending e-mail...");
           Transport.send(mimeMessage);
           System.out.println("e-mail sent.");
       }
        catch(MessagingException me)
       {
           System.out.println("e-mail send failed."+me);
           me.getMessage();
       }
    }
}

The important difference between this code listing and the one for sending email in the previous section is the process of building the message body, which is now capable of adding a file as an attachment. The Multipart class is actually split into two sections, the message part and the attachment. The properties are actually the same as for the previous code listing.

You could use Multipart instead of MimeMultipart, but be aware that Multipart is an abstract class and hence requires you to create an instance of MimeMultipart. It’s a similar case with MimeMessage. You can use Message, which also is an abstract class. Understanding all the classes used here will help you familiarize yourself with the mail package.

The article has provided enough information for you to experiment with sending and receiving emails. But you need to know-

• The details in the properties file must be accurate to achieve the desired results.
• Ensure that you have mail.jar and activation.jar in your classpath.

Code Profiling

A (code) profiler is a performance analysis tool that measures only the frequency and duration of function calls, but there are other specific types of profilers in addition to more comprehensive profilers, capable of gathering extensive performance data.

You may not notice any performance issues unless you use code profiling to assist you. For general PHP profiling, programmers often use xdebug with all sort of PHP applications including wordpress. But, if you’re a wordpress theme developer, usually all you need is a MySQL profiler.

WP MySQL Profiler

This simple plugin will assist both theme and plugin developers in MySQL Profiling. Once installed, MySQL statistics will be available at page footer.

Installation

• Download WP MySQL Profiler and extract the archive.
• Rename your wp-db.php file in wp-includes directory to wp-db-backup.php.
• Upload wp-db.php included in the archive to your wp-includes directory.
• Upload wpSqlProfiler.php to wp-content/plugins/ directory.
• Edit your wp-config.php. Find define (‘WPLANG’, ”); and add below:               define(’SAVEQUERIES’, true);
• Enable “WP MySQL Profiler” plugin from the admin CP.

Usage

You will see MySQL query details at page footer, when you will log in as an admin. Keep an eye on both total queries and time. Each time you add code to your templates, use the profiling information to check if an optimized function or code snippet has been used.

If you notice high total queries or time, examine the queries and check the backtrace (below) to find where the query originated from. And then remove or replace the unoptimized function/code.

The Backtrace

In the profiler, third column will give you the most important information. It started at themes/default/single.php on line 7 with the function get_header() which called function wp_head(), kubrick_header_display() and finally get_option() in the file functions.php on line 83.

Note that there’s a link “Show Full Trace”. For simplicity, the profiler doesn’t show all the function calls by default. Instead, it tries to determine function calls from plugins and themes. Since you are going to use it when coding plugins and themes, it makes sense to assume that you’re concerned with function calls originating therein.

Final Steps

And if you want to use the same wordpress copy on a live site, make sure to:

• delete the wp-db.php and rename wp-db-backup.php to wp-db.php. (optional)
• remove define(‘SAVEQUERIES’, true); from wp-config.php.

Similarly, disable the WP MySQL Profiler plugin.

To generate a “Share to Google Buzz” link, you just need to add the following code in between your WordPress Posts Loop.

<a href=’http://www.google.com/reader/link?url=<?php the_permalink(); ?>&title=<?php the_title(); ?>&snippet=<?php the_title(); ?>&srcURL=<?php bloginfo(’wpurl’); ?>&srcTitle=<?php bloginfo(’name’); ?>’>Share to Google Buzz</a>

The link contains 4 parameters:

url: link to blog post
title: blog post title
srcURL: source url like your blog url
srcTitle: your blog name or title

It’s a simplest and plugin free way to add Google Buzz to your blog posts. If you want, you can add a Google Buzz icon instead of text link in the above code.

To begin, let’s have a look at the groundwork.

The cURL Component-

cURL (or “client for URLS”) is a command-line tool for getting or sending files using URL syntax. It was first used in 2007 by Daniel Stenberg as a way to transfer files via protocols such as HTTP, FTP, Gopher, and many others, via a command-line interface. Since then, many more contributors has participated in further developing cURL, and the tool is used widely today.

Using cURL with PHP-

PHP is one of the languages that provide full support for cURL. (Find a listing of all the PHP functions you can use for cURL.) Luckily, PHP also enables you to use cURL without invoking the command line, making it much easier to use cURL while the server is executing. The example below demonstrates how to retrieve a page called example.com using cURL and PHP.

<?php


$ch = curl_init(”http://www.example.com/”);
$fp = fopen(”example_homepage.txt”, “w”);


curl_setopt($ch, cURLOPT_FILE, $fp);
curl_setopt($ch, cURLOPT_HEADER, 0);


curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

The Link Scraper-

For the link scraper, you will use cURL to get the content of the page you are looking for, and then you will use some DOM to grab the links and insert them into your database. You can build the database from the information below; it is really simple stuff.

$query = mysql_query(”select URL from links where visited != 1);
if($query)
{

 	while($query = mysql_fetch_array($result))

 	{

$target_url = $query['url'];
$userAgent = ‘ScraperBot’;

Next, grab the URL from the database table inside a simple while loop.

$ch = curl_init();
curl_setopt($ch, cURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, cURLOPT_URL,$target_url);

After instantiating cURL, you use curl_setopt() to set the USER AGENT in the HTTP_REQUEST, and then tell cURL which page you are hoping to retrieve.

curl_setopt($qw, cURLOPT_FAILONERROR, true);
curl_setopt($qw, cURLOPT_FOLLOWLOCATION, true);
curl_setopt($qw, cURLOPT_AUTOREFERER, true);
curl_setopt($qw, cURLOPT_RETURNTRANSFER,true);
curl_setopt($qw, cURLOPT_TIMEOUT, 20);

You’ve set a few more HEADERS with curl_setopt(). This time, you made sure that when an error occurs the script will return a failed result, and you set the timeout of each page followed to 20 seconds. Usually, a standard server will time-out at 30 seconds, but if you run this from your localhost you should be able to set up a no-timeout server.

$html= curl_exec($qw);
if (!$html)
{

 	echo "ERROR NUMBER: ".curl_errno($ch);

 	echo "ERROR: ".curl_error($ch);

 	exit;

}

Grab the actual page by sending the HEADERS along while executing the cURL request using curl_exec(). If an error occurs, it will be reported to PHP by the number and description inside curl_errno() and curl_error, respectively. Obviously, if such an error exists, you exit the script.

$dom = new DOMDocument();
@$dom->loadHTML($html);

Next, you create a document model of your HTML (that you grabbed from the remote server) and set it up as a DOM object.

$xpath = new DOMXPath($dom);
$href = $xpath->evaluate(”/html/body//a”);

Use XPATH to grab all the links on the page.

for ($i = 0; $i < $href->length; $i++) {

 	$data = $href->item($i);

        $url = $data->getAttribute('href');

 	$query = "INSERT INTO links (url, gathered_from) VALUES ('$url', '$gathered_from')";

 	mysql_query($query) or die('Error, insert query failed');

        echo "Successful Link Harvest: ".$url;

 	}

}

Dump all the links into the database, as well as the URL they are gathered from, just so you never go back there again. A more intelligent system might have a separate table for URLs already visited, as well as a normalized relationship between the two.

Going a step further than just grabbing the links enables you to harvest images or entire HTML documents as well. This is kind of where you start when building a search engine. Creating your own search engine may seem naively ambitious, and this little bit of code may inspire you a bit.

Here, you can get the same following 4 steps-

Step 1: Create your Customer Class

The first step is to create the customer class as shown below. So the customer class has 4 properties on customer id, first name, address and designation.

public class Customers
{
// private properties
private int _intCustomerID;
private string _strFirstName;
private string _strAddress;
private string _strDesignation;

// Public property and
public int CustomerID
{
get
{
return _intCustomerID;
}
set
{
_intCustomerID = value;
}
}
public string FirstName
{
get
{
return _strFirstName;
}
set
{
_strFirstName = value;
}
}

Step 2: Create your Web Service

The next step is to create the web service which exposes the customer class to UI. Here is a simple web service which has encapsulated customer collection. In the constructor, we are loading some dummy data into the list of customers as shown in the below code snippet:

[System.Web.Script.Services.ScriptService]
public class Customer : System.Web.Services.WebService {

// Customer collection
List<Customers> listcust = new List<Customers>();
public Customer ()
{
//Load some dummy data in to customer collection.
listcust.Clear();

Customers cust = new Customers();
cust.CustomerID = 1;
cust.FirstName = “Dan”;
cust.Address = “Live in UK”;
cust.Designation = “Software Developer”;
listcust.Add(cust);

cust = new Customers();
cust.CustomerID = 2;
cust.FirstName = “Sheen”;
cust.Address = “Live in Austrailia”;
cust.Designation = “Web Designer”;
listcust.Add(cust);

cust = new Customers();
cust.CustomerID = 3;
cust.FirstName = “Koraine”;
cust.Address = “Live in London”;
cust.Designation = “Architect”;
listcust.Add(cust);
}

// This function exposes all customers to the end client’
[WebMethod]
public List<Customers> LoadCustomers()
{
return listcust;
}

// This function helps us to get customer object based in ID
[WebMethod]
public Customers LoadSingleCustomers(int _customerid)
{
return (Customers)listcust[_customerid-1];
}

Two functions have been exposed with the web service, one which gives out a list of customers and another which gives out individual customer data based on customer id.

Step 3: Reference your Web Service using the asp:servicereference

Using the ‘asp:ServiceReference’, the path to the ASMX file will be pointed as shown in the below code snippet. This will generate the JavaScript proxy which can be used to call the customer object.

<asp:ScriptManager ID="ScriptManager1" runat="server">

    <Services>

        <asp:ServiceReference Path="Customer.asmx" />

    </Services>

</asp:ScriptManager>

Step 4: Call the Webservice and the JavaScript Code

Once you have defined the proxy, you can now call the ‘Customer’ proxy directly to make method calls.

function LoadAll()
{
Customer.LoadCustomers(LoadCustomerToSelectOption, ErrorHandler, TimeOutHandler);
}

When you call the JavaScript proxy object, then you need to provide three functions; the first function (‘LoadCustomerToSelectOption’) will be called when the web service finishes and returns data. The data will be returned in the fill variable which will then be looped and added to the customer combo box.

function LoadCustomerToSelectOption(Fill)
{
var select = document.getElementById(”cmbCustomers“);

for (var i = 0; i < Fill.length; i++)
{
var value = new Option(Fill[i].FirstName, Fill[i].CustomerID);
select.options.add(value);
}
}

There are two more functions which are attached; one which handles error and the other which handles time out.

function ErrorHandler(result)
{
var msg = result.get_exceptionType() + “\r\n“;
msg += result.get_message() + “\r\n“;
msg += result.get_stackTrace();
alert(msg);
}
function TimeOutHandler(result)
{
alert(”Timeout :” + result);
}

Many style sheets include repeated styling information because CSS does not allow the use of variables. Such repetition makes the resulting style sheet lengthier and harder to read; it results in more rules that need to be changed when the website is redesigned to use a new primary color.

In order to specify the inherited CSS rules, such as indicating that the elements in h1 elements should not be underlined, requires creating a single selector name, like h1 a. Ideally, CSS would allow for nested rules, enabling you to define the rules directly within the h1 rules.

.LESS is a free, open-source port of Ruby’s LESS library. LESS (and .LESS, by extension) is a parser that allows web developers to create style sheets using new and improved language features, including variables, operations, mixins, and nested rules.

Behind the scenes, .LESS converts the enhanced CSS rules into standard CSS rules. This conversion can happen automatically and on-demand through the use of an HTTP Handler, or done manually as part of the build process. Moreover, .LESS can be configured to automatically minify the resulting CSS, saving bandwidth and making the end user’s experience a snappier one.

Steps to creating an image map-

• Select the image on which you would like to make multiple links. Click on the rectangular hotspot tool found in the Properties Inspector. Select the rectangle tool and drag the pointer over the image to create a rectangular hotspot. You can also choose the oval or polygon hotspot tool to make an oval or polygon selection.
• In the hotspot Property inspector’s Link field, click the folder icon to browse to the file you want opened when the hotspot is clicked. Alternatively, type the file name.
• Repeat the above steps to define additional hotspots in the image map.
• That’s it! You have now successfully created an image map.

For example-

<DIV ALIGN=CENTER>

<MAP NAME=”map1″>

<AREA

HREF=”contacts.html” ALT=”Contacts” TITLE=”Contacts”

SHAPE=RECT COORDS=”6,116,97,184″>

<AREA

HREF=”products.html” ALT=”Products” TITLE=”Products”

SHAPE=CIRCLE COORDS=”251,143,47″>

<AREA

HREF=”new.html” ALT=”New!” TITLE=”New!”

SHAPE=POLY COORDS=”150,217, 190,257, 150,297,110,257″>

</MAP>

<IMG SRC=”testmap.gif”

ALT=”map of GH site” BORDER=0 WIDTH=300 HEIGHT=300

USEMAP=”#map1″><BR>

[ <A HREF="contacts.html" ALT="Contacts">Contacts</A> ]

[ <A HREF="products.html" ALT="Products">Products</A> ]

[ <A HREF="new.html"      ALT="New!">New!</A> ]

</DIV>

Using this, you can create an image map.

key features of “HyperSQL“:

• flexible configuration by use of .ini files
• generates nicely formatted HTML files, CSS adjustable by use of .css files
• parses SQL, C++ and Java files according to file extensions you configured
• generates hyperlinked listings of all objects found (SQL views, packages, functions, procedures, etc.)
• hyperlinks object names to their appearance in the source code
• generates “where used” lists, to show where your objects have been used by other objects (if they have) – helps you to find unused code if not, or example usages if found

Newly included:

• option blind_offset added (to control parsing for “anonymous JavaDoc segments”)
• code reorganization: outsourced some code to modules (hyperjdoc, hypercore, hypercode)
• “describing” JavaDoc elements (with just one “text” option) can now span multiple lines
• converting crash when configured top_level_directory did not exist into a standard exit with proper error message
• fixed the additional empty lines in code listings
• new keyword include_source (section Process) to make the inclusion of source code optional

eLyXer 0.4.1 is a LyX to HTML converter, with a focus on flexibility and elegant output. LyX is a wonderful text editor which produces beautiful PDF files. Internally it exports documents to LaTeX, and from there to PDF. It can convert documents generated with LyX versions from 1.5.5 to 1.6.2 into valid HTML pages.

The output requires XHTML, CSS2 and Unicode; therefore a CSS2-compatible browser is required.

Minimum browser versions for some popular programs are: Microsoft Internet Explorer 7, Mozilla Firefox 3, Safari 3 and Chrome 1. It requires Python 2.3.4 or higher

It consists of –

• Select the translation based on document language.
• Added em-dash — such as in this sentence, ■, \textup.
• Added option –converter inkscape to use Inkscape as SVG converter.
• Solved bug when numbering unordered unique parts such as Part* (thanks, Geremy!).
• Show error instead of crashing when included document does not exist.
• Support for all box styles. In CSS: switched to outline-style instead of border for boxes.
• Support for vertical space insets.
• Support for references inside paragraphs and formatted references.
• Listings are now converted using <pre> tags, instead of <code>. They are also justified left.
• Solved bug that prevented numbered listings to appear numbered (thanks, Sam!).
• Support for generic Flex insets, including Flex CharStyle: MenuItem.
• All entities are now generated as the Unicode U+00A0 character.
• New option –iso885915 to generate a document with ISO-8859-15 encoding.
• Support for Sam Liddicott’s Newfangle module for literate programming.
• Updated the developer guide for potential contributors; added link from the main page.
• Support for \underbrace and \overbrace.

It is compiled into XHTML, similarly to ERB, and attempts to fix many flaws in templating engines like explicitly coding HTML into the template.

Haml itself is a description of the HTML, with code to generate dynamic content. And it functions as a replacement for inline page templating systems such as PHP, ASP, and ERB.

Example:
The #foo Hello World! line of code will output this HTML line of code: <div id=”foo”>Helo World!</div>

Automatically, Haml handled the end tag and tag defining. For CSS stylings, SASS does the same thing as Haml does for HTML. SASS is bundled with Haml by default.

Apache Commons Transaction 1.2 is the Java library, which contains implementations for multi level locks, transactional collections and transactional file access

Commons Transaction aims at providing standardized, lightweight, well tested and efficient implementations of utility classes commonly used in transactional Java development.

Initially there are implementations for multi level locks, transactional collections and transactional file access.

There may be additional implementations when the common need for them becomes obvious, however, the complete component shall remain compatible to JDK1.2 and should have minimal dependencies.

To allow ONLY authenticated access to your site using Forms authentication you can add a section like this on e to your application’s web.config file.

<authentication mode="Forms">

    <forms loginUrl="Login.aspx" name="Login" protection="All"/>

</authentication>

<authorization>

    <deny users="?"/>

</authorization>

The problem is that it seems lots of folks don’t want users to automatically redirect to the Login.aspx page when they navigate to their site home page.

To require authentication for all the pages in your
web application EXCEPT the home page (Default.aspx))

Also add a location section to your web.config file that explicitly allows anonymous users to access JUST the default.aspx page.

<location path="default.aspx">

    <system.web>

      <authorization>

         <allow users="*"/>

      </authorization>

    </system.web>

</location>

You can use the web.config location element to specify folders as well as pages which makes it a very powerful construct.

This isn’t a problem but, the user needed to clicking the OK button to cause a post-back so that he could execute some server –side logic.

The ”Ok” Button is an ASP.NET control but adding a Click Event Handler for the button didn’t solve the problem because it didn’t get executed when the use Clicked on the “Ok” button.

Normally the ModalPopupExtender would be used like this.

    <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server"

                 TargetControlID="LinkButton1"

                 PopupControlID="Panel1"

                 BackgroundCssClass="modalBackground"

                 DropShadow="true"

     1.)         OkControlID="OkButton"

     2.)         OnOkScript="onOk()"

                 CancelControlID="CancelButton" />

Line number 1 tells the control to catch the click event for the Ok Button Control instance and line 2 specifies when CLIENT SIDE JavaScript code to execute when the control specifies in line 1 is clicked.

The post-back doesn’t happen (even if the ASP.NET Button control has a click event handler defined in code behind because the control doesn’t propagate it.)

So Just delete those two lines !

It turns out that they are optional and if you delete them the click event is not trapped and the code behind will execute as expected.

So just nake it look like this:

    <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server"

                 TargetControlID="LinkButton1"

                 PopupControlID="Panel1"

                 BackgroundCssClass="modalBackground"

                 DropShadow="true"

                 CancelControlID="CancelButton" />

In terms of usability, breadcrumbs reduce the number of actions a website visitor needs to take in order to get to a higher-level page, and they improve the find ability of website sections and pages.

Benefits of Using Breadcrumbs-

• Convenient for users- Breadcrumbs are used primarily to give users a secondary means of navigating a website. By offering a breadcrumb trail for all pages on a large multi-level website, users can navigate to higher-level categories more easily.
• Reduces clicks or actions to return to higher-level pages- Instead of using the browser’s “Back” button or the website’s primary navigation to return to a higher-level page, users can now use the breadcrumbs with a fewer number of clicks.
• Doesn’t usually hog screen space- Because they’re typically horizontally oriented and plainly styled, breadcrumb trails don’t take up a lot of space on the page. The benefit is that they have little to no negative impact in terms of content overload, and they outweigh any negatives if used properly.
• Reduces bounce rates- Breadcrumb trails can be a great way to entice first-time visitors to peruse a website after having viewed the landing page. For example, say a user arrives on a page through a Google search, seeing a breadcrumb trail may tempt that user to click to higher-level pages to view related topics of interests. This, in turn, reduces the overall website bounce rate.

When we don’t need to use the breadcrumb
A common mistake in implementing breadcrumbs is using them when there is no benefit.

In the above example. The (1) primary navigation, (2) breadcrumb trail and (3) secondary navigation are very close together. The breadcrumb trail in this application offers users no added convenience because the secondary navigation for lower-level pages sits right below it. Additionally, clicking on the second-level link in the breadcrumb trail (”Music”) takes you back to the first tab (”Listen”), which mistakenly suggests that the first tab is on a higher level than the other two (”Search” and “Artist hall of fame”).

Add breadcrumb-

You can easily add them via several good plugins (ex. Yoast Breadcrumbs), but sometimes you want to build breadcrumbs into a theme without using a plugin.

Step: 1. Created a php file called breadcrumbs.php and inserted the following code…

/*Breadcrumbs*/
function the_breadcrumb() {
echo ‘You are here: ‘;
if (!is_home()) {
echo ‘‘;
echo ‘Home’;
echo “ » “;
if (is_category() || is_single()) {
if (is_single()) {
echo the_title();
}
} elseif (is_page()) {
echo the_title();
}
elseif (is_tag()) {
single_tag_title();
}
elseif (is_day()) {
echo “Archive for “; the_time(’F jS, Y’);
}
elseif (is_month()) {
echo “Archive for “; the_time(’F, Y’);
}
elseif (is_year()) {
echo “Archive for “; the_time(’Y');
}
elseif (is_author()) {
echo “Author Archive”;
}
elseif (isset($_GET['paged']) && !empty($_GET['paged'])) {
echo “Blog Archives”;
}
elseif (is_search()) {
echo “Search Results”;
}
elseif (is_404()) {
echo “404 Error”;
}
}else{
echo ‘‘;
echo ‘Home’;
echo ““;
}
}
?>
/*End of Breadcrumbs*/

In Windows Vista, click on the round Windows logo button on the bottom left hand side of your desktop and go to “All Programs” – “Accessories” – “Sound Recorder.”

You can record your own .wav files to be placed within your web page for your visitors to hear.

Once you’ve created your sound file and uploaded it to your server, place the following code within your web page where you would like the control panel to appear. This code is compatible with both Internet Explorer and Netscape Navigator.

Change the text indicated in red to your sound file.

The “autostart” determines whether or not the sound will play when the page loads. “True” specifies that the sound will start on load and “False” specifies that the sound will not start on load.

The “loop” determines how the sound should be played. “False” specifies that the sound should not loop and will play it through one time. “True” specifies that the sound should loop and play continuously. It is highly recommended that you leave this set on false.

The “hidden” specifies whether or not the music’s control panel should be displayed. “True” specifies that the control panel should be hidden. “False” specifies that the control panel should be displayed. It is highly recommended that you leave this set on false. This will enable your visitors to stop the sound if they prefer.

As ASP.NET technology evolved, the application level Web.config had new things added to it. Since the earlier frameworks were using the same set of machine level configuration files, incremental feature that was added subsequent to the 2.0 release resulted in additional config settings included in the file.
.NET 4 web.config

With .NET 4, the web.config is tremendously reduced in size to improve the simplicity of ASP.NET

The config settings have been moved down to the machine config file. This includes registers all of the ASP.NET tag sections, handlers, modules and settings for the following:
• ASP.NET AJAX
• ASP.NET Dynamic Data
• ASP.NET Routing
• ASP.NET Chart Control

You can look at the trimmed down web.config by creating a .Net 4 ‘ASP.NET Empty Web Application’ in Visual Studio 2010.

Following is the web.config file for .NET 4 C# ‘ASP.NET Empty Web Application’:

The config file above has settings to tell ASP.NET to enable debugging by default for the application and provides the version of .NET framework to use.

Having trackbacks, pingbacks and comments all mixed up in one place can get really messy and confusing. Let’s separate the trackbacks and the pingbacks from comments-

<?php if ($comments) : ?>

<li id=”comment-<?php comment_ID() ?>” class=’commentItem’>

<!– THE COMMENT LAYOUT –>

</li>

<?php endforeach; /* end for each comment */ ?>

</ol>

if($commentType == ‘comment’) :

?>

<li id=”comment-<?php comment_ID() ?>” class=’commentItem’>

<!– THE COMMENT LAYOUT –>

</li>

<?php endif;/* end if comment check */ ?>

<?php endforeach; /* end for each comment */ ?>

</ol>

<?php endif; ?>

get_comment_type is a function that returns “comment”, “trackback” or “pingback” depending what type the current comment is.

Now just copy paste the same code again and just change “if($commentType == ‘comment’)” toif($commentType != ‘comment’) which is the opposite of “==” and change the class from“commentItem” to “trackbackItem” so you can easily make different styles.

<?php if ($comments) : ?>

<ol>

<?php foreach ($comments as $comment) : ?>

<?php

$commentType = get_comment_type();

if($commentType != ‘comment’) :

?>

<li id=”comment-<?php comment_ID() ?>” class=’trackbackItem’>

<!– THE PINGS LAYOUT –>

</li>

<?php endif;/* end if NOT comment check */ ?>

<?php endforeach; /* end for each comment */ ?>

</ol>

<?php endif; ?>

Making the layout for pingbacks/trackbacks is very simple, there is only 1 function we are going to use, comment_author_link(). It just echoes the trackback/pingbacks link and that’s all we need.

<li id=”comment-<?php comment_ID() ?>” class=’trackbackItem’>

<?php comment_author_link(); ?>

</li>

At least in php. Php 5.3 has a solution that will reduce the average number of iteration structures you need to write: closures applied by plain old array functions.

There are some array functions which have already been supported at least from Php 4, and that take as an argument a callback whose formal parameters have to be one or two elements of the array. Let’s talk about array_map(), array_reduce(), array_filter() and uasort() (or similar custom sorting function.) These functions abstract away a foreach() cycle by applying a particular computation to all the elements of an array.

Back in Php 4 and Php 5.2, specifying a callback was cumbersome: you had to define an external function and then passing its name as a string; or passing an array containing an object or the class name plus the method name in case of a public (possibly static) method.

In Php 5.3, callbacks may also be specified as anonymous functions, defined in the middle of other code. These closures are first class citizens, and are treated as you would treat a variable, by passing it around as a method parameter. While I am not a fan of mixing up object-oriented and functional programming, closures can be a time saver which capture very well the intent of low-level processing code, avoiding the foreach() noise.

// obviously only the prime numbers less than 20
$primeNumbers = array(2, 3, 5, 7, 11, 13, 17, 19);

// uasort() customize the sorting by value,
// maintaining the association with keys
// there is the native asort(), but again the customization
// of the function is more interesting
$compare = function($a, $b) {
if ($a == $b) {
return 0;
}
return ($a > $b) ? -1 : 1;
};
uasort($primeNumbers, $compare);
echo “The given numbers in descending order are: “,
implode(’, ‘, $primeNumbers), “.\n”;

For software platforms on cellphones, the market is led by the Nokia’s Symbian operating system, but it has lost much ground over the last year to Apple Inc and Research in Motion, maker of the BlackBerry.

Linux, the computer operating system, is starting to win traction with Google Inc using Linux to build its Android platform, and Nokia rolling out its top-of-the-range model N900 using Linux Maemo.

According to head of LiMo, Morgan Gillis, there has been a step change for Linux in mobile. No other operating system now matches the vendor coverage of Linux — it is being commercially deployed by virtually all leading mobile device vendors from the largest downwards.

LiMo, a non-profit foundation, hopes to benefit from its focus on giving greater say over software development to telecoms operators.

The role of top operators in the platform – Vodafone uses it in its 360 offering – is a key attraction for Adobe, whose Flash is among the world’s most widely used web-based computer programs, and it has some 1.6 million developers.

Vodafone and other operators have strongly pledged for a smaller number of operating systems, as supporting them is a timely and costly exercise. However, in recent years, the number of large operating systems has increased, with new players like Apple and Google entering the mobile market.

In a latest twist Samsung Electronics — the world’s second largest handset maker and one of the key members of LiMo – unveiled in late 2009 its own smartphone platform.

Linux is the most popular type of free or so-called open source computer operating system which is available to the public to be used, revised and shared. Linux suppliers earn money selling improvements and technical services, and Linux competes directly with Microsoft, which charges for its Windows software and opposes freely sharing its code.

Japanese electronics firms NEC and Panasonic, and Israeli firm Else unveiled on Monday a total of seven new phones running on LiMo software.

If your hard disk is clogged with massive photos and Microsoft Office documents, or if you’re looking for a better way to share those large files, consider FileMinimizer Suite 6.0. This simple-to-use software reduces photo sizes by approximately 90 percent with little noticeable degradation of on-screen quality, and typically it shrinks Office files by at least 25 percent, with no quality loss.

FileMinimizer does not create .zip archives containing your data; the files it creates retain their original format and are usable just as the originals are, so .jpg files remain .jpg files, .ppt files remain .ppt files, and so on. It handles Excel, PowerPoint, and Word files, as well as an assortment of image file formats (such as .jpg, .png, .gif, .tif, .bmp, and .emf).

The basic operation couldn’t be simpler. Choose the files that you want to compress and select the compression strength (low, standard, or strong), and FileMinimizer quickly goes about its work, taking only a few seconds to compress each individual file.

By default it keeps your original file and creates a new one, appending the text ‘(FILEminimizer)’ to the name. However, you can tell the program to overwrite your original file, and you can also have the utility apply a different name rather than appending the ‘(FILEminimizer)’ label.

Based on the former BEA Weblogic Workshop development tool runtime, Beehive was built on J2EE and the Struts Java Web framework; it used annotations to reduce coding.

According to project management committee chair for the Beehive project, Eddie O’Neil, it’s a project that had been at Apache for several years.

“Over time, the rate of contributions to the project declined, and it just slowed down and we didn’t do any more releases of it,” O’Neil said.

The project has been moved to The Apache Attic, where discontinued projects go. The project got more mature, and it just kind of finished, according to O’Neil.

In 2008, Oracle acquired BEA but the acquisition had no bearing on the discontinuance of the project. O’Neil added that Beehive already had been fairly inactive prior to the deal.

Apache is suggesting alternatives to Beehive technologies.

Beehive NetUI/Page Flow users can switch to Struts 2 or Spring Web Flow while Beehive Controls users can move to Spring Beans. Users of Beehive WSM (Web service metadata) can switch to Axis2’s implementation of Java Specification Request 181, which is entitled, “Web Services Metadata for the Java Platform.”

According to IBM, the Power7 chip has up to eight cores, with each core able to run four threads. A Power7 chip can run 32 tasks simultaneously, which is quadruple the number of cores on the older Power6 chip. The Power7 will also run up to eight times more threads than Power6 cores.

During a press event in New York on Monday, Ross Mauri, general manager of IBM’s Power Systems unit, said Power7 chips will run between 3.0GHz and 4.14GHz. The chip will come with four, six or eight cores.

The chips are being made using the 45-nm process technology. The company has made memory-level improvements that should enable the processor to execute tasks faster.

Power7 systems will deliver twice the performance of older Power6 systems, but be four times more energy efficient, according to Mauri. The systems will run operating systems including AIX and enterprise Linux offered by Red Hat and Suse.

The new chip also has TurboCore technology, which allows customers to crank up the speed of active cores for performance gains. The technology also puts memory and bandwidth from eight cores behind the four active cores to drive up the performance gains per core.

The company also launched four Power7-based servers. IBM Power 780 and Power 770 high-end servers are based on modular designs and come with up to 64 Power7 cores. The IBM Power 755 will support up to 32 Power7 cores. The company also launched the 750 Express server. The Power 750 Express and 755 will ship on Feb. 19, while the Power 770 and 780 will become available on March 16.

In addition to boosting performance, the Power7 servers can save more energy. A technology called Unique Intelligent Energy allows parts of a system to be switched off to reduce power drawn. The technology also allows the processor clock speed to be cranked down on a single server or across a pool of multiple servers, which can reduce power consumed.

Representative of IBM declined to provide server pricing, and said it would be competitively priced. Rod Adkins, senior vice president of IBM’s Systems and Technology group, said the servers will deliver better performance and bang for the buck than existing Power6 systems.

IBM officials called the chip the “world’s fastest processor,” but emphasized that system performance will be measured by the ability to deliver “intelligent” performance.

Adkins said, “As we conceived this Power7 system… raw performance was a given. What you will see is a tremendous focus around … intelligent performance”. He also added that a mass of data will flood servers as computing expands to devices like mobile devices and smart meters.

This data will need to be collected, processed and analyzed on the fly. For example, collecting data will allow utilities to instantly analyze energy usage patterns, and new ways to acquire energy from multiple sources.
