[RESOLVED] hook question

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.

There are bunch of hooking samples that you can find here.

This is from moeur, it will allow you to subclass external programs.

thank you very much, both, Guys.
fast valuable help !
