Thus I thought to help you guys and gals out. here is how you get rid of this Torjan horse virus from your PC and pen drive.

First clear your PC and then clear your pen-drive.

start => run => cmd
goto directory c:\windows => c:\cd windows => c:\windows\>
type this – attrib -s -h -r -a autorun.inf
del/f autofrun.inf
goto sytem32 folder => c:\windows\ cd system32 => c:\windows\system32\>
type this – attrib -s -h -r -a explorar.exe
del/f explorar.exe
goto pendriver directory from command prompt
type this – attrib -s -h -r -a autorun.inf
type this – attrib -s -h -r -a *.*

After that open the USB driver ( Do not double click. right click on the Drive=>explore)
Delete the autorun.inf file and unknow exe files in the USB.
Now its complete.
Restart the computer.

There are Only 20 seats are available at the first batch and they will be given in “First come First served” order. The second batch will start in May 2011. For more information call 077 38 676 38 OR contact IIS CITY CAMPUS by phone 222 8060 or 222 2201.

This program will educate you HTML to Search Engine Marketing. All essential languages and tools to master Web Development.

Scheduled start of the program is last week of April. For any further information please contact IIS City Campus by email enquiry@iisCityCampus.com or by phone 222 8060 or 222 2201.

To rehabilitate the city, it is also important to educate and employ the youths from Jaffna. By extending OLPC project to Jaffna, Information Technology can be introduced at root level as the first step of Sri Lanka’s IT hub.

Current knowledge within Jaffna residence is limited. IT educational institution and foreign degree providers are mushrooming in Jaffna to make their best balance sheet ever. The biggest question is How much worth Certificate, Diploma etc provided by these institutions have? Do those students get employed? What is the major concern of this institution is the profit not social responsibility.

There is a big Local market potential for Information Technology. If you have noticed that there is NO web site of any community is up to standard. The Internet could play a big role as to bridge the gab to seek employment far away from local market. Education the youths in IT will prepare for the world market than just local market.

I hope at the least one NGO will come forward to extend OLPC project to Jaffna.

Thank you,

Currently I am looking to rent a Computer Lab with min. 20 PCs to conduct these courses. We will be establishing our own facility soon depends on demand for offline courses.

Learning the Basic web languages is free of charge for online users. Interactive online classes will be introduced in July.

I am aimed at promoting education to take advantage of global employment opportunities to the Young dynamic individuals from Jaffna.

• What am I expected to learn? At the end of the courses you will be able to design a web site using open source Content Management System. Customize the core CMS files, create Templates, Develop custom functions, etc.
• What are the employment possibilities are successfully completing the course? You can employ your self as Web Developer at local or any international company. Work to foreign companies while living in Jaffna.

PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since. The main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification. PHP is free software released under the PHP License, which is incompatible with the GNU General Public License (GPL) because restrictions exist regarding the use of the term PHP.

PHP originally stood for personal home page. It began in 1994 as a set of Common Gateway Interface (CGI) binaries written in the C programming language by the Danish/Greenlandic programmer Rasmus Lerdorf. Lerdorf initially created these Personal Home Page Tools to replace a small set of Perl scripts he had been using to maintain his personal homepage. The tools were used to perform tasks such as displaying his résumé and recording how much traffic his page was receiving. He combined these binaries with his Form Interpreter to create PHP/FI, which had more functionality. PHP/FI included a larger implementation for the C programming language and could communicate with databases, enabling the building of simple, dynamic web applications. Lerdorf released PHP publicly on June 8, 1995 to accelerate bug location and improve the code. This release was named PHP version 2 and already had the basic functionality that PHP has today. This included Perl-like variables, form handling, and the ability to embed HTML. The syntax was similar to Perl but was more limited, simpler, and less consistent.

Zeev Suraski and Andi Gutmans, two Israeli developers at the Technion IIT, rewrote the parser in 1997 and formed the base of PHP 3, changing the language’s name to the recursive initialism PHP: Hypertext Preprocessor. The development team officially released PHP/FI 2 in November 1997 after months of beta testing. Afterwards, public testing of PHP 3 began, and the official launch came in June 1998. Suraski and Gutmans then started a new rewrite of PHP’s core, producing the Zend Engine in 1999. They also founded Zend Technologies in Ramat Gan, Israel.

On May 22, 2000, PHP 4, powered by the Zend Engine 1.0, was released. As of August, 2008 this branch is up to version 4.4.9. PHP 4 is no longer under development nor will any security updates be released. On July 13, 2004, PHP 5 was released, powered by the new Zend Engine II. PHP 5 included new features such as improved support for object-oriented programming, the PHP Data Objects extension (which defines a lightweight and consistent interface for accessing databases), and numerous performance enhancements. In 2008, PHP 5 became the only stable version under development. Late static binding has been missing from PHP and has been added in version 5.3. PHP 6 is under development alongside PHP 5. Major changes include the removal of register_globals, magic quotes, and safe mode. The reason for the removals was that register_globals had given way to security holes, and magic quotes had an unpredictable nature, and was best avoided. Instead, to escape characters, magic quotes may be substituted with the addslashes() function, or more appropriately an escape mechanism specific to the database vendor itself like mysql_real_escape_string() for MySQL. Functions that will be removed in PHP 6 have been deprecated in PHP 5.3 and will produce a warning if used.

Many high-profile open-source projects ceased to support PHP 4 in new code as of February 5, 2008, because of the GoPHP5 initiative, provided by a consortium of PHP developers promoting the transition from PHP 4 to PHP 5.

PHP currently does not have native support for Unicode or multibyte strings; Unicode support will be included in PHP 6 and will allow strings as well as class, method and function names to contain non-ASCII characters.

PHP interpreters are available on both 32-bit and 64-bit operating systems, but on Microsoft Windows the only official distribution is a 32-bit implementation, requiring Windows 32-bit compatibility mode while using Internet Information Services (IIS) on a 64-bit Windows platform. As of PHP 5.3.0, experimental 64-bit versions are available for MS Windows.

This example will demonstrate a poll where a web page can get results without reloading.

Example Explained – The HTML page

The HTML page contains a link to an external JavaScript, an HTML form, and a div element:

The HTML form works like this:

1. An event is triggered when the user selects the "yes" or "no" option
2. When the event is triggered, the function getVote() is executed
3. The data returned from the getVote() function will replace the form, in the <div> tag

Example Explained – The JavaScript code

This is the JavaScript code stored in the file "poll.js":

The stateChanged() and GetXmlHttpObject functions are the same as in the PHP AJAX Suggest chapter.

The getVote() Function

This function executes when "yes" or "no" is selected in the HTML form.

1. Calls the GetXmlHttpObject() function to create an XMLHTTP object
2. Defines the URL (filename) to send to the server
3. Adds a parameter (vote) to the URL with the content of the input field
4. Adds a random number to prevent the server from using a cached file
5. Each time the readyState property changes, the stateChanged() function will be executed
6. Opens the XMLHTTP object with the given url.
7. Sends an HTTP request to the server

The PHP Page

The server page called by the JavaScript code is a simple PHP file called "poll_vote.php".

The selected value is sent from the JavaScript and the following happens:

1. Get the content of the "poll_result.txt" file
2. Put the content of the file in variables and add one to the selected variable
3. Write the result to the "poll_result.txt" file
4. Output a graphical representation of the poll result

The Text File

The text file (poll_result.txt) is where we store the data from the poll.

It is stored like this:

The first number represents the "Yes" votes, the second number represents the "No" votes.

Note: Remember to allow your web server to edit the text file. Do NOT give everyone access, just the web server (PHP).

AJAX RSS Reader

In this example we will demonstrate an RSS reader, where the content from the RSS is loaded into a webpage without refreshing.

Example Explained – The HTML page

The HTML page contains a link to an external JavaScript, an HTML form, and a div element:

The HTML form works like this:

1. An event is triggered when a user selects an option in the drop-down box
2. When the event is triggered, the function showRSS() is executed
3. The <div id="rssOutput"> is a placeholder for the data returned from the showRSS() function

Example Explained – The JavaScript code

This is the JavaScript code stored in the file "getrss.js":

The stateChanged() and GetXmlHttpObject functions are the same as in the PHP AJAX Suggest chapter.

The showRSS() Function

Every time an option is selected in the input field, this function executes the following:

1. Calls the GetXmlHttpObject() function to create an XMLHTTP object
2. Defines the URL (filename) to send to the server
3. Adds a parameter (q) to the URL with the selected option from the drop-down list
4. Adds a random number to prevent the server from using a cached file
5. Each time the readyState property changes, the stateChanged() function will be executed
6. Opens the XMLHTTP object with the given URL
7. Sends an HTTP request to the server

Example Explained – The PHP page

The PHP page called by the JavaScript code is called "getrss.php":

When an option is sent from the JavaScript, the following happens:

1. PHP finds out which RSS feed was selected
2. An XML DOM object is created for the selected RSS feed
3. The elements from the RSS channel are found and outputted
4. Loops through the first three elements and output result

AJAX Live Search

In this example we will demonstrate a live search, where you get search results while you type.

Live search has many benefits compared to traditional searching:

• Results are shown as you type
• Results narrow as you continue typing
• If results become too narrow, remove characters to see a broader result

Search for a W3Schools page in the input field below:

In the example above, the results are found in an XML document (links.xml). To make this example small and simple, only eight results are available.

Example Explained – The HTML page

The HTML page contains a link to an external JavaScript, some style definitions, an HTML form, and a div element:

The HTML form works like this:

1. An event is triggered when the user presses, and releases a key in the input field
2. When the event is triggered, the function showResult() is executed
3. The <div id="livesearch"> is a placeholder for the data returned from the showResult() function

Example Explained – The JavaScript code

This is the JavaScript code stored in the file "livesearch.js":

The GetXmlHttpObject() function is the same as in the PHP AJAX Suggest chapter.

The showResult() Function

This function executes every time a character is entered in the input field. If there is no input in the text field (str.length == 0), the function sets the return field to empty and removes the border around it. However, if there is any input in the text field, the function executes the following:

1. Calls the GetXmlHttpObject() function to create an XMLHTTP object
2. Defines the URL (filename) to send to the server
3. Adds a parameter (q) to the URL with the content of the input field
4. Adds a random number to prevent the server from using a cached file
5. Each time the readyState property changes, the stateChanged() function will be executed
6. Opens the XMLHTTP object with the given URL
7. Sends an HTTP request to the server

The stateChanged() Function

This function executes every time the state of the XMLHTTP object changes. When the state changes to 4 ("complete"), the content of the txtHint placeholder is filled with the response text, and a border is set around the field.

Example Explained – The PHP page

The PHP page called by the JavaScript code is called "livesearch.php".

The code searches an XML file for titles matching the search string and returns the result as HTML:

If there is any text sent from the JavaScript (strlen($q) > 0), the following happens:

1. PHP creates an XML DOM object of the "links.xml" file
2. Loops through all  <title> elements to find titles that match the text sent from the JavaScript
3. Sets the correct link and title in the "$response" variable. If more than one match is found, all matches are added to the variable
4. If no matches are found, the $response variable is set to "no suggestion"
5. Output the $respone variable to the "livesearch" placeholder
