Thread: MDI msg proc

I have a Multiple Document Interface app with an edit control within one of the documents and I want it to have it's own msg procedure. How would I do this with a MDI? I'm new to the Win API so if anyone can help, that would be good.

i think it is the same as an SDI, similar procedures.

It is'nt. I've tried.

If you dont know how to use an MSG box then here is the solution:
AfxMessageBox("string goes here");

make sure StdAfx.h is include in the .cpp file.

Why did you tell me that?

WNDPROC OldEditProc;


LRESULT CALLBACK NewEditProc (HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {
switch (message) {
...
}
return CallWindowProc (OldEditProc, hWnd, message, wParam, lParam);
}



hWndEdit = GetDlgItem (/* MDI child window handle */, /* Edit window ID */);

OldEditProc = (WNDPROC) SetWindowLong (hWndEdit, GWL_WNDPROC, (LONG) NewEditProc);
