Re: catching CMainFrame::OnEndSession

I typically just put my close out code in mainframe's OnClose() or the main
applications ExitInstance(). Typically when the system wants to shut down
it will send messages to applications and MFC automatically sets up your
program to respond favorably, but you an hook into the message:

http://msdn2.microsoft.com/en-us/library/2163xa6f(VS.80).aspx

and set up your own behavior, like checking to make sure a thread is
complete and not allowing Windows to shutdown otherwise. You can also hook
into:

http://msdn2.microsoft.com/en-us/library/zz2fsz7y(VS.80).aspx

I'd only block Windows shutting down if my program was doing someting that
absolutely needs to finish. Otherwise, and most of the time, I just stop
what I'm doing immediately in my mainframe's OnClose() method and don't even
mess with these messages.
