Hi,
Isn't "OnKeyDown"/"OnKeyUp" fast enough?

If your program should recieve (and maybe process) the keyboard message first, try a hook function (see: SetWindowsHookEx). This will gain some extra microseconds.

And of course there is DirectX 5 - DirectInput as described in Mircosoft Press's 'Inside Direct X'. But I have never tried it myself...

Generally I would recommend using 'OnKeyDown'/'OnKeyUp' as the savest and easiest solution.

. and set the repetition rate in the control panel/keyboard to maximum.

Yup, as the guys told you what you should do I guess I don't need to repeat that suggestion again.... OnKeyPress/OnKeyDown/OnKeyUp/SetWindowsHookEx/UnhookWindows.....and so on.....

P.S. Especially for games I guess the Hook is better, but it's more comlex to implement.... By complex I mean that you need more, code, more though, and a DLL which should be provided with your program...
