Disable CTRL-ALT-DEL and ALT-TAB, Windows Key etc in NT/2000

Hello ppl

Is it possible to block usage of CTRL-ALT-DEL, ALT-TAB, the Windows key etc in Windows NT/2000? I have Karl Moore's code for Windows 9x based platforms which works perfectly for those OS's but it doesn't work for WinNT and Win2k. Any ideas?

The Windows 9x based code was:

VB Code:

Private Const SPI_SCREENSAVERRUNNING = 97
 
Declare Function SystemParametersInfo Lib "user32" _
    Alias "SystemParametersInfoA" (ByVal uAction As _
    Long, ByVal uParam As Long, lpvParam As Any, ByVal _
    fuWinIni As Long) As Long
 
Public Sub EnableTaskKeys(Enabled As Boolean)
 
If Enabled = False Then
    'Disable task keys
    SystemParametersInfo SPI_SCREENSAVERRUNNING, 1&, 0&, 0
Else
    'Enable task keys
    SystemParametersInfo SPI_SCREENSAVERRUNNING, 0&, 0&, 0
End If
 
End Sub

then

VB Code:

' To disable task keys
Call EnableTaskKeys(False)

to disable the task keys, and:

VB Code:

' To enable task keys
Call EnableTaskKeys(True)

to re-enable them.

TIA.

Or if that's impossible, is it possible to acknowledge when CTRL-ALT-DEL etc is pressed under Windows NT/2000?

Thanks.

I asked this question a few days ago. Tygur says its impossible, so it probably is:mad:

Okay thanks :)

Is it possible, however to call the "Lock Computer" option which is built into NT/2000 (CTRL-ALT-DEL then choose Lock Computer) in VB?

I would imagine that thats possible through APIs. You might want to post on the API forum. Of course, most people who look on that forum look here to...

Okay - thanks for your help :)
