How would I disable the use of keys? Ctrl+Alt+Delete

[stefonalfaro]

I have been searching for ever and I think this may be impossible? Im not sure. I just need to know how to disable keys from being used. Because if you cant disable keys then Visual Basic is useless.

You can disable the use of many keys, however, you cannot disable the ctrl+alt+delete key combination.

I believe you have to replace msgina.dll with your own copy.. Ctrl+Alt+Del actually generates an interrupt that windows listens to. The reasoon it is used to bring up the login prompt is that its very very hard to write a program that steals the login prompt to harvest passwords.

I would actually recommend that you take the approach that most internet kiosks do:

Provide a metal, indesctructible keyboard that doesnt have the left alt key present, at all

what about alt+f4? Could that be disabled

 

[cjard]

removing the left Alt would certainly do it

Yes, in the keydown event do:

       If (e.Alt = True) Then
            If (e.KeyData = Keys.F4) Then
                e.Handled = True
            End If
        End If
