Edit: this script is obsolete as there are ways to do this without the dll.

see here.

Necessity is the Mother of invention.

Example of using Larry's hook.dll to hook a MsgBox and move it anywhere on the screen. Call the _MsgBoxAu3() function the same as a regular MsgBox but with extra params for x,y,w,h

Really nice job eltorro!

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

pretty cool eltorrro

I think this should be the path?

$dll = @ScriptDir & "\hook.dll"; Where did that dll go????
If that's where you have it. :D

Great!

@ everyone,

Thanks needs to go to Larry for his dll. As without it... well, the script doesn't work.

Thanks Larry :D
