For API Gurus!! System-Wide hooking!!

[Zej]

How do I create a System-Wide hook? SetWindowsHookEx will only let me create it locally (By locally I mean not system wide). I think i need a DLL for this but can someone give me an example? it can be in C or C++ or VB or whatever language.

Thanks for reading!

If your hook is WH_MOUSE or WH_KEYBOARD or WH_CALLWNDPROC then you can replace it with WH_JOURNALRECORD which is one of the only 2 system-wide hooks which don't need a DLL.

Whew, long sentence.
Hope it's decipherable.

Would my callback still process the events?? say if I made a key logger, would it log the keys that i type in a different program as well?

Yes, it can be system-wide with no DLL and it can replace WH_KEYBOARD. Read the MSDN help, it's all there.
