As a postscript to my previous article on this approach, I'd
like to add that no matter what it is you are trying to do,
this is a very bad idea.  Don't do it.  If you don't care 
about the confirmation message box, just send the MS-DOS 
Executive this message exclusively.  Broadcasting an SC_CLOSE
message like this will almost certainly cause the debugging
version of windows to crash if the user decides to cancel
at confirmation time.  The reason is that this message will
close some windows you don't want closed if you're not really
leaving Windows.

You can get the window handle for the MS-DOS Executive with:

		hWnd = FindWindow( "Session", NULL );

This works even with foreign language versions of Windows.
