Hello,

First of all, are you displaying your message box before or after 
calling the parent TWindow::SetupWindow() in your SetupWindow() function?
After calling TWindow::SetupWindow() the window should be fully created
and you can post a WM_QUIT message (using the API function 
PostQuitMessage()) if you want to exit.


If you want the message box to be shown along with the main window of 
the application, you can do it in the first WM_SHOWWINDOW message.

If you do not care if the main window is displayed,
then you can try something else:
In the OWLMain() function, call
::MessageBox(NULL, "Run the application?", "Question", MB_OKCANCEL)
and if the user chooses to cancel, exit without even creating 
TApplicaton, main windows, etc.
