Thread: API and Rich edit control

I wrote an app for a friend with MFC, but it won't run on his computer for some unknown reason. Anyway, I'm rewriting it with API, but I am not an API programmer, so I need some assistance.

I have a rich edit control and I want to handle the WM_CHAR and WM_KEYDOWN messages (among others) and know that I need to create a separate procedure to handle the richedit's messages, but I don't know how to do that... I've created it with CreateWindowEx(), but how do I tell the app where to send its messages?

Thanks yo.

Something along the lines of SetWindowLong() with the GWL_WNDPROC flag. Pass in a function pointer to your new procedure to redirect the control's messages.

The msgs are sent to the parents or owners HWND as supplied. The resouce ID is cast as the HMENU param.

change on fly

Code:

//get old WNDPROC to send msg's  we are not interested in back to
    lpfnDefOldProc = (WNDPROC)GetWindowLong(hWnd, GWL_WNDPROC);
//set to the new WNDPROC
    SetWindowLong(hWnd, GWL_WNDPROC, (LONG)NewWndProc);
