  afx_msg BOOL OnQueryEndSession();
 
  Remarks
 
  Called when the user chooses to end the Windows session or when an
  application calls the ◄ExitWindows► Windows function. If any application
  returns FALSE, the Windows session is not ended. Windows stops calling
  OnQueryEndSession as soon as one application returns FALSE, and sends
  the ◄WM_ENDSESSION► message with a parameter value of FALSE for any
  applications that have already returned TRUE.
 
  This message-handler member function calls the ◄Default► member
  function. Override this member function in your derived class to handle
  the ◄WM_QUERYENDSESSION► message.
 
  Return Value
 
  An application should return TRUE if it can be conveniently shut down;
  otherwise FALSE.
