As far as I'm aware AutoIt has plenty of functionality but is a bit lacking (or at best, is clunky) when dealing with hooking a client and manipulating a specific function inside of it...
Either way it's far more work than it's worth especially when there's so many public hooking examples on the forums already.
Personally I strongly advise staying away from auto it for any serious project. It has it's uses and is far from useless but it just isn't going to be able to efficiently do a lot of things and this is one of them.
Ps: Yes, you got some rude responses and that sucks but the way you worded the question was kinnddaaa troll bait.
