Under Win NT environment how to disable Alt-Tab, Ctrl-Esc and Ctrl-Alt-Del by using VB ?

I want to disable Alt-Tab, Ctrl-Esc and Ctrl-Alt-Del while my application is running in Win NT4.0 environment. Can someone tell me how to do it by using visual basic ? Thank you.

You can disable CTRL+ESC on a system-wide basis by replacing the NT Task Manager. This is not recommended.

You can disable ALT+TAB and ALT+ESC while a particular application is running if that application registers hotkeys for those combinations with Register HotKey().

Another mechanism to disable these key combinations, as well as the newer Windows key, is to use a low level keyboard hook (WH_KEYBOARD_LL).API -SetWindowsHookEx().
This hook is available on Windows NT 4.0 Service Pack 3 and later. The low level keyboard hook can also detect CTRL+ALT+DEL, but it cannot disable it.
