Keyboardhook and Hotkey?

hi all,

I have heard that you must use an dll for the windows keyboard hook apis to work in Win2000/XP in a global state, is that correct? If so then why?

Is there any other way to "hide" or prevent applications from recieving keystroke messages? If so then how?

Does hotkey apis prevent messages and must they always use combined keys like ctrl+..., alt+... or shift+...?

I thank you for any reply

Can't you hook the keyboard, and don't call CallNextHookEx() for the keys you want to stop?
Just a suggestion, I've never tried it..

You need a dll because the hook function you create needs to be added to every process that you are hooking....having the code just in your program isnt good enough

If you create the hook, you can use it to filter messages, but I wont tell you how because it can be misused.

Does this also apply to Windows XP and NT? And what about Windows 95, 98 and ME, do they need dll declaration too?

Applies to ALL Win32 Platforms......even 95

If you only want hotkeys, use
RegisterHotKey()

But does HotKeys prevent key messages to other applications and must they always use combined keys like ctrl+..., alt+... or shift+...?
