How to handle messages of sub window in MFC.开发者_如何学Python I created a menu and when I'm clicking the menu, the program creates a dialog window.

How do I close the menu window when its dialog window is closed?

If dialog is modal:

Close the parent window after returning from DoModal;

You don't return from DoModal until the dialog is closed.

If dialog is not modal:

When you initialize the dialog, send a pointer of the parent to the dialog.

Close the parent using the pointer, where you capture the dialog close event.
