Hello

I have the following code, but when I use Alt = True, Ctrl = True and Key = Keys.Delete, I do not get the Taskmanager which you should get with ALT, CTRL and DELETE

What is wrong?

   Private Sub DoKeyBoard(ByVal Shift As Boolean, ByVal alt As Boolean, ByVal ctrl As Boolean, ByVal key As Keys)
        Dim KEYEVENTF_KEYUP As Byte = &H2
        If ctrl = True Then
            keybd_event(Keys.ControlKey, 0, 0, 0)              
        End If
        If alt = True Then
            keybd_event(18, 0, 0, 0)            
        End If
        If Shift = True Then
            keybd_event(Keys.ShiftKey, 0, 0, 0)              
        End If
        keybd_event(key, 0, 0, 0)            
        keybd_event(key, 0, KEYEVENTF_KEYUP, 0)
        If Shift = True Then
            keybd_event(Keys.ShiftKey, 0, KEYEVENTF_KEYUP, 0)
        End If
        If alt = True Then
            keybd_event(18, 0, KEYEVENTF_KEYUP, 0)
        End If
        If ctrl = True Then
            keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0) ' Generates a KEY_UP
        End If
    End Sub

You can't generate a Ctrl-Alt-Del combination in this manner.

It is handled by the kernel at a much lower level.

If it was that easy to bring up the task manager it would be a snap to fool the user into typing in their password while your keyboard logger records everything!

To do this you would basically need to write your own GINA.DLL to handle SAS requests:

What are you trying to do here?...

Ok thanks, thats ok.

Actually I am creating a remote control with my POcketPC, and I just wanted to test if the CTRL, ALT and SHIFT-Keys are working correctly. I have now simulated other keystrokes (Ctrl + Esc, Alt + F4) and that is working... Just thought that my code is not working for simulating keystrokes...

Thanks
