WM_KEYDOWN is called when any key in the keyboard is pressed. how to find which key is pressed?

Aha. You should tell what exactly do you mean by "which" key, but I think I can guess by your example above. Please see my answer.

The question is not clear, but I can guess by "key number" you mean a raw key identifier (which comes into play before a key is recognized as a status key, character key, etc.), which is called "scan code". You can get it as lower byte of the parameter nFlags of CWnd::OnKeyDown; please see:

See also: http://en.wikipedia.org/wiki/Scan_code[^].

You can extract scan code from nFlags like this:

C++

byte scanCode = nFlags & 0xFF;
