MFC dialog A invokes dialog B, and dialog B creates modeless dialog M.
When the focus is in M and user types Enter, I want the dialog M to be
destroyed and dialog B exited, as if user had typed Enter while focus
was in B.

I'm catching Enter in M (by overriding OnOK), and executing OnOK in
the parent, B. This closes B, but does not redraw A.

How can I accomplish the effect I am looking for?

For a modeless dialoog, you must override OnOk and OnCancel to call DestroyWindow and NOT
call the superclass OnOK and OnCancel handlers. This is important, because if you do, or
you fail to override them, you will get serious malfunctions.

Note that if you fail to override OnCancel, hitting <ESC> will cause problems. If you
don;t want <ESC> to do anything, have an empty body for OnCancel.


PostMessage a WM_COMMAND:IDOK message to the dialog you want closed.

You should transfer a pointer to the desired dialog in a variable of the modeless dialog;
don't use GetParent() because it will give you the wrong pointer for a modeless dialog.

I had not called DestroyWindow, but I have now added that.

Since I have gotten burned by this one before, I did remember to do
that.

This seems to work fine. Tnx for the prompt reply.
