I'm trying to send a message from the parent window to the child window that makes the child resize when the parent does. I get an unhandled exception when I try this. Any suggestions?
This was my first atempt at sending a message between windows, so I don't know what I did wrong.
1 2 3 4 5
SendMessage(hWnd, WM_SIZE, wParam, lParam);
//hWnd is the child window's handle, the rest are all the same info
//that the parent receives when resized.
