Killing the session on click of Brwoser X

Hi,

Can anyone please let me know, how to kill the application session when the user clicks on the browser "X" button to close the browser.

I have googled and none of the examples seems to be working, appreciate a sample code.

Thanks,
Deb

If someone kills the browser, the server has no way of knowing. It just has to wait for the session to timeout.

You need one javascript function to capture browser unload event and one hidden server control button with click event. In that javascript function write code to click the hidden button. In the button click event you can do the actions you want like session clean up.

Ex:
//Javascript

javascript:window.onbeforeunload = function(){
   if((window.event.clientX<0) ||
      (window.event.clientY<0)){
      if(document.getElementById("ctl00$testbutton")!=null)
      document.getElementById("ctl00$testbutton").onclick();
   }
     
 }

//button event

protected void testbutton_ServerClick(object sender, EventArgs e)
    {        Session["test"]=null; //close particular session
        //or
       Session.Abandon();//close all sessions
}

Hope it helps

The same thing could be accomplished with an AJAX call and avoiding another postback.

Also, using JQuery to find the DOM elements is more resilient than using getElementById, IMO.

Could I improve my class which contains multiple class references

Im trying to see if there is a better way of doing something that I have implemented. In our project we have a class that contains alot of generic list properties, for example

public class Portfolio
 'I haven't declared the variables but you get the idea

 public property Client as list(of client)
   'Get and Set
 end property

 public property Covers as list(of covers)
   'get and set
 end property

 public property HomeQuotes as list(of HomeQuotes)
   'get and set
 end property

 'Other Properties that would make up a clients insurance portfolio
 'but there are alot to mention
end class

All the data is taken from the database using a LINQ to SQL. I have looked at using IoC container but am not sure that they are the best way to go as this container rarely changes in contents.

Any reference materials or that you could point me too or tips that you could give I would be grateful.

This really belongs into the ASP.NET forum and it should also contain code-formatting tags (see the link code above the editing textbox).

.Net and Windows API

I am not .Net developer. I am just curious.

First of all, as far I understand .Net is suppose to be platform independent. That is why it compile targeting (I think I read somewhere) a Virtual processor.

Now if a developer use WIN32 API in there .Net Application will it be plat form independent at all? I believe no it wont be. Then what is the real purpose of developing a .Net application that would take too much memory, and make my old machine tired?

.NET is NOT platform independent. .NET is Microsofts implementation of the Common Language Infrastructure (CLI - which Microsoft wrote BTW) for Windows. Mono is another open source implementation of the CLI for Linux. General code that doesn't use any implementation specific libraries should work on any implementation.

When you start getting into the implementation specific stuff, like WPF in Windows, of course that's not going to work on Mono because Linux doesn't have WPF.

Any code you write that P/Invokes Win32 functions, obviously, will not work on anything other than a version of Windows that implements those functions.

No, it won't. Again, you seem to have some misconceptions on what .NET is and how it works.

Simply put, Win32 API code never run on a MAC.

Hi,I am working on a project to manage information of our faculty from ASP.net in C#.
There are profiles for lecturer,student and department head.When Admin set privileges to do tasks Eg:edit student details, this should be appear only in the lecturer profile as a links to edit those data.
So, I want to create the admin page with ability to do those tasks and I have no idea to do that Frown | :(
