Process Hide Visual Basic Help Ayuda

[Harmmy]

I want to hide my project list taskmgr.exe.
help?
Hide process ?

[Elemental Code]

hi, i once used a piece of code that hided the proces from the taskmanager process list by hacking into and hiding it from the listbox.
The problem was that the memory needed by taskmanager went up as long as it was open.

I cant remember the name, but cant be that hard to find.
