Forcing an update of one modeless child dialog from another child

Question

My first project was working fine until I tried making it more visually appealing.

On initilization, my main dialog creates an output dialog with three sections of read-only fields. The main dialog has 3 buttons, each producing a dialog corresponding to a section of the output dialog. It is from these user entry dialogs where the user is allowed to update data/common. Upon exiting I'm doing an Invalidate( TRUE ) on the output dialog in the OnPaint section of maindlg to force an update of its fields. Everything is fine to this point.

Now I set the x/y coordinates on the 3 user entry dialogs to pop up just beneath the corresponding output section, rather than on top of maindlg. Now, I see, the maindlg has no need to "paint" when I exit.

So, how can I force an update of my outdlg from each of my user entry dialogs, all being childs of maindlg.

Solution 1

The typical approach used is to PostMessage a user-defined message from dialog-1 to dialog-2. Dialog-2 handles this user-defined messages and invalidates itself.
