Capture Window and Subclassing / Hooking
 

Hi,

I am trying to make a program that mimics the boss protection style of Messenger Plus and many other add-ons (my program is not for msn though).

How do I do this? Is there a way to change the icon of any system tray application, and capture all of its windows? Somebody please help me

Also,
How do you subclass and hook, using VB, objects that are not part of your program? I can't seem to get it to work.

Look up the FindWindow, FindWindowEx, and ShowWindow api calls. I believe there's also some that allow enumeration of windows, but don't know it off the top of my head.
