Webmaster Forum / Browsers / Internet Explorer / December 2005

It can't be done.

If you need the functionality of a Windows program, then write one using
your favorite language (VB, C++, etc). You cannot force a browser to behave
like a Windows application. The browser is controlled by the user, not the
programmer.

Oh, you can get part of the way there by creating an HTA (HTML Application),
but that has its own issues.

Sachin,
You can disable this keycode combination for a specific web application
using javascript.  However, the user will still be able to access this
same action via the File menu.  But you could solve this by hiding the
menubar as well and providing your own customized menu.  Here's an
example of how to catch and suppress the keycode combination Ctrl+N:
<script language="javascript">
<!--
document.onkeydown =
   function KeyDownHandler(e)
   {
     // Ctrl key was pressed
     if (event.ctrlKey)
     {
    // supports multiple browsers
    var keyCode =
           document.layers ? e.which :
        document.all ? event.keyCode :
        document.getElementById ? e.keyCode : 0;

    // N key was pressed
    if (keyCode == 78)
    {
        event.returnValue = false;
        event.cancel = true;
        alert("Ctrl + N was pressed");
    }
     }
   }
// -->
</script>
As far as hiding the menubar and all of those tricks, I'll leave up to
you as I'm sure you'll be able to google that and find someone who has
done it.  You could simply open a new window and hide it via the
window.open command.
Hope that helps.
