Application Process in WinNT Task Manager

I've been searching the forum for information on hiding applications in vb, and found the "app" function. The only problem is that in WinNT the application still shows up in the process window of the task manager. If anyone could help me with some info on how to solve this problem I would greatly appreciate it.

I am looking for the API Function to Hide my Application in the Taskmanager.

May you as kind as to give me an Example how you declare the API und how you call it?

Thx,
