this is a good example of how to hook the keyboard and stop any key combo you want:

also searching google for 'visual basic keyboard hook' will have more examples

This function should do it.


  Private Declare Function SystemParametersInfo Lib _
  "user32" Alias "SystemParametersInfoA" (ByVal uAction _
  As Long, ByVal uParam As Long, ByVal lpvParam As Any, _
  ByVal fuWinIni As Long) As Long          

Code

  Sub DisableCtrlAltDelete(bDisabled As Boolean)
     Dim X As Long
     X = SystemParametersInfo(97, bDisabled, CStr(1), 0)
  End Sub

You CANNOT disable Ctrl-Alt-Del in any way shape or form on Windows NT. No matter how hard you try, this question has been asked many times here and elsewhere and there is NO solution to it that has yet been found.

yes thats true, in nt ctrl+alt+del is a considered its onwn interrupt

this is the only thing out there that will intercept it - its not free =[

I am not sure about NT or Windows 98 but I know in windows xp there is a registry key to block the Task manager ( which is what you get after you press ctrl + alt + delete ). Not sure if that is what you wanted though.
