I am writing a program for my school that restricts access to various areas. This has been asked before for regular VB but I would like to know if it's possible to disable Ctrl-Alt-Delete for both Windows 9x and NT/2000. I've seen various samples of code for disabling it in 9x and NT/2000 for regular Visual Basic but I wouldn't know how to get that to work in .net.

Is it possible to do this? If not what's a good way to prevent people from closing my program down using the task manager?
