When Windows is about to shut down, it sends a WM_QueryEndSession to all open applications. To detect (and prevent shutdown), we must define a message handler to this message.This is a delphi implement:http://delphi.about.com/cs/adptips2...bltip0500_4.htm

Private Sub Form_Unload(Cancel As Integer)
cancel=1
End Sub
