[RESOLVED] hook question

[whatsup]

I want to filter keyboards events, of other (not mine at all) application,

of course with pure API calls.

so i need a way to install a pointer to my procedure, that executed,
on each keyboard/message event, and after that proceed to that other application

does someone have an example code ?


I tried to use GetWindowLong/SetWindowLong
to install my procedure, but these don't work with other threads handles.

I saw also SetWindowsHookEx that may do that, but i couldn't understand exactly, it seems that i need to pre-install this hook function, in a dll.
