PBM: Message box not displayed after main dialog box is closed in MFC dialog-based app
Vince:
Yes, you cannot show another modal dialog (or message box, same thing)
after the main window is closed. I'm not sure what the impact of simply
not telling MFC that the main dialog is the main window, but I would
suggest putting the message box in the OnOK or OnCancel handler of the
dialog.
BTW, the same thing happens in DocView applications. There you can put
the messagebox/dialogin the WM_CLOSE handler for the main window.
HTH,
