I think that you can only test for Ctrl + Alt or Alt + Del etc, I do not think you can test for all keys down at the same time (not without setting one of their values to false). And I think it will only work on Windows 9x systems, on later ones you would just get the task viewer thing.

find a code snippet to disable ctrl alt + del. use a timer and in its event, use GetAsyncKeyState to check to see if they're all pressed. if they are, then go ahead and show form2.

I have never seen code to disable control+alt+delete. There is code to disable the task manager, but you will still get a window on NT systems because ctrl+alt+delete is very secure in the NT kernel.

i don't know about NT, but i know you can do it with 98.

ive never used nt, but supposedly telling windows its running a screen saver works.
im not sure, but i dont think you can test for one of the keys with getasynckeystate (alt key?) maybe im wrong, but i always tested with getkeyboardstate, since it takes a snapshot of every key position making it real easy to determine if any number of keys are pressed at the same time.

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Const VK_DELETE = &H2E
Const VK_CONTROL = &H11
Const VK_MENU = &H12
'set the interval to 1 millisecond on a timer control
Private Sub Timer1_Timer()
If GetAsyncKeyState(VK_CONTROL) <> 0 And GetAsyncKeyState(VK_MENU) <> 0 And GetAsyncKeyState(VK_DELETE) <> 0 Then
  MsgBox "Control+Alt+Delete was pressed"
End If
End Sub

As you can see, this code won't work on Windows 2000. Not sure about any operating system, but I doubt it will work on anything with the NT kernel in it.
