`$hooker = $hook->Call($idHOOK, $lpfn, $hmod, $dwThreadId);` IIRC, $lpfn is supposed to be a reference to a subroutine so that it can be used as a callback.	[reply] [d/l]

Eh, what?!? No, a callback expects a pointer to some raw machine code (generally compiled C), which the CPU can then execute directly. Pure Perl won't do, you'll need an interface layer written in XS. I looked over CPAN, and found Win32::API::Callback, which probably can be used to get the desired effect. If it doesn't crash. :)	[reply]
