[AutoIT] Key spamming

[maffer]

Hey there i'm looking for an AutoIT bot/Script that can spam a key in a infinity loop(Numpad1).

While 1
    Send("{NUMPAD1}")
WEnd

Besides that i want it to attach to a window process/ID.

- I want this program for a 'project/test' i'm working on with about 30 + wow processes. Therefore i'm wondering if it's possible to read the char name as well when you have to attach the bot.

( Yes i tried other key spammers but AutoIT is the only thing that works. I just need some help with the window ID's / Attaching)
