Substitute For System Wide Hook In VB

First off i would like to say you guys have a great forum here, i have been on reading for about a mouth now and have learned so much.

Second i have a question. I have been looking all over for a way to do a system wide hook on window creation with in VB as iv read there's no way to do this so i ask is there a "substitute" for this ?

Let me give you a little background on what I'm trying to do, i have anywhere from 1 to 10 windows some i have partial captions others i have full captions and i know the class of all windows. What I'm trying to do is be able to get the hwnd of these windows when they are created and then ether close them or store the hwnd for later use.

Last but not least speed is a key in what I'm trying to do, with the windows I'm blocking (closing) they need to be handled as fast as possible.

Thanks to anyone that can help me and once again i think this site is wonderful and has been a great help to me. :)
