Disable the "special" keys

[Codius]

I'm looking for a way to disable the special keys on a keyboard, such as ALT+F4, ALT+TAB, CTRL+ESC, WindowsKey, AppKey and so on..
I've been told that dWinLock is the best and easiest way to do this, but I don't want to use someone elses DLL file :/
I've been looking a little at keyboard hooking, trying to just recieve the key and don't send it, but it doesn't work

Any help/code will be helpful.
Thanks in advance, Codius

you don't need such stuff like extarnal dll's, simply use winapi keyboardhook (more on msdn). it's few lines of code and it's simple like hello world
