How to make another application invisible??

Okay,

I'm using Visual Basic 6.0 in Win98. Is there any kind of way to make another application invisible (if I know app's name in the tasklist ["ctrl+alt+del"])? Or how can I make all the other windows to be on top so this application's window wont be seen. Oh..this is hard to explain.....Well could somebody help me? Give ideas or maybe tips...

well what u could do is keep the program running, and just hide the form, don't unload it, just hide it... "form1.hide"... also if u want to hide your program from the task list, "CTRL+ALT+DEL"... well u can do that using the API, look in the VB-world.net site, u should find it, or search for it on the forum, I'm sure u'll find it..

Well, I didn't mean that... My purpose is to hide another program than my own. For example: How is it possible to hide (not just minimize) Internet Exlorer's window from my own application? But I want that Internet Explorer still keeps running in the background.

ShowWindow API shows/hides and iswindowvisible retrieves if it's visible/not
