This thread is for discussions of Disable Ctrl+Alt+Del.

I've seen this lots of times on many sites. Does anyone know how to trap CAD in NT/2000?

This is the only way to intercept Ctrl+Alt+Del on NT/2000/XP

Here is a work around to ctrl-alt-delete if your goal is only to prevent the user from using task manager.  If you put this in a timer with a Interval of 1 then the instant task mangager comes up an alt f4 is sent closing it.

Code:

On Error GoTo exitsub
AppActivate "Windows Task Manager"
thesendkeys = "%{F4}"
SendKeys (thesendkeys)
Exit Sub
exitsub:
Exit Sub

Try this http://www.developerfusion.com/show/2112/
by passing the same Caption...

no need to use SendKeys...

I just thought of this a while ago. This works by making the OS think a screen saver is running... So what happens if the user manually runs one and closes it? The OS will re-enable the keys!

There is a system registery key that controls the task manager. If you set its value to 1, the task manager is disabled!The code for that would be:

Dim Path As String

       Path = "Software\Microsoft\Windows\CurrentVersion\Policies\System\"
       Microsoft.Win32.Registry.CurrentUser.OpenSubKey(Path, True).SetValue("DisableTaskMgr", 1)

If you use the same code again and change the registery value to 0, the task manager will be enabled again!

Thanks for the tip...

Is there a similar way to disable the START button too???

In Specific... the CTRL+C and Windows APP key ( vKeyCode = 91)
