Default Re: How can communicate between child and parent windows in VC++ win32 application?
When you click a button with the mouse the child window control sends a WM_COMMAND message to its parent window. The program traps the WM_COMMAND message and displays the values of wparam (child window ID and notification code) and lparam (child window handle). The notification code indicates in more detail what the message means.
