Log off cancellation notification to applications

Hello Experts,
My application runs on Windows 7 and when the user initiates a Windows Log-Off, I receive the message WM_QUERYENDSESSION through the method 'WindowProc'. At this point, I also get windows 'Force log off' screen as shown in the attached screenshot. When I click on cancel on this screen, is there any way that I can interpret this event in my program. I mean, just the way a log-off sent WM_QUERYENDSESSION, will I be notified with any message saying the log-off process was cancelled.

Regards.

Not sure if this applies but in this article http://msdn.microsoft.com/en-za/library/ms700677%28v=vs.85%29.aspx It says

If any top level window returns FALSE to WM_QUERYENDSESSION, the shutdown is cancelled, and each top level window that was sent WM_QUERYENDSESSION will be sent WM_ENDSESSION with wParam == FALSE.

The article refers to XP but check to see if you don't get the WM_ENDSESSION message with param = FALSE
