I've got an MFC dialog app, and need a way of returning a value when the app ends. I want to return which button was clicked for use in a batch file. MFC puts this comment in the app:
// Since the dialog has been closed, return FALSE so that we exit the // application, rather than start the application's message pump.
So how do I return a value?
Thanks.

? Return values from a Dialog App
EndDialog([id of the button pressed])
This will be the value returned by DoModal()
Good luck -- BW

? Return values from a Dialog App
If you are using MFC dialog-based app wizard, before this line, you can see the program call dlg.DoModal(). After that, you can check the return value to see which button you have clicked to end the dialog.

? Return values from a Dialog App
In addition to your other replies, take a look at CWinApp::ExitInstance.
