Hi all. I'm wondering if you can make your program <u>totally</u> invisible for windows task manager. I tryed some stuff once. Well it just hides the windows, but when you press ALT-TAB you still see it.

If someone can help me, please send me some code.
Would be very appreciated

(Using Delphi 6 & Win9x & WinNT/2k)

umm... try this?

RegisterServiceProcess(GetCurrentProcessId(), 1); to remove from task manager

and this:

  ExtendedStyle: Integer;
  ExtendedStyle := GetWindowLong (Application.Handle, GWL_EXSTYLE);
  SetWindowLong(Application.Handle, GWL_EXSTYLE,

to remove from Alt+Tab
