I have created a Flash application that contains its own close button. When the use clicks this button, it saves a few final values to a database through an ASP page. If, however, the student chooses to close the browser either by using Alt-F4 or its X button, I'm unable to save the necessary data. So here's my question...

Is there a way to determine which method the user is trying to use to close the browser and display a message if one of the other methods is used?

Hi,

You can use the window object's onbeforeunload method to catch closures, but the problem is it also picks up on refresh too as it has to unload the page to reload it. Also, AFAIK there's no way to actually stop a window from closing once the user requests it. You could force the window to reopen but at the risk of losing any form data they may have inputted, but you could store this in cookies (if they have them enabled). There's questions all over google about this, but I've never seen anyone manage it. Surely you run the risk of annoying the crap outta your users though if they can't close their browser?

Hii chrscote!!
how this will help you
<script>

function saveData()
{
 //capturing ALT + F4
 if (event.altKey==true && event.keyCode==0 )
{
  //alert("closed1")
 document.location.href="SessionEndFile.asp";
   window.close();
  }

Xwidth=window.document.body.offsetWidth-window.event.clientX
YHeight=window.event.clientY
if(Xwidth<=30&&YHeight<0)
{
  // alert("closed2")
 document.location.href="SaveDataFile.asp";
   window.close();

}

}
window.onbeforeunload=saveData
//or we can use body(unload) method

</script>

Cheers :)
