You can create an OnMove handler for WM_MOVE messages to detect when your window moves. In the handler, you can either move the other window directly with MoveWindow, or you can send a private message to the window (something in the WM_APP range would be best) and let it move itself. Use GetWindowRect to get the width and height to pass to MoveWindow.
