afx_msg BOOL OnQueryEndSession( );
Return Value
Nonzero if an application can be conveniently shut down; otherwise 0.
Remarks
The framework calls this member function when the user chooses to end the Windows session or when an application calls the ExitWindows Windows function. If any application returns 0, the Windows session is not ended. Windows stops calling OnQueryEndSession as soon as one application returns 0 and sends the WM_ENDSESSION message with a parameter value of FALSE for any application that has already returned nonzero.
