Doing CTRL-ALT-DEL

[mborchers]

Hi guys,

Within Visual Basic, how do I send "CTRL-ALT-DEL"? All I want to do is bring up the Windows Security box, but SendKeys doesn't permit the combination...

Any code appreciated!

Best wishes,

you cant. ctrl+alt+del is protected for reasons of security.

actually.. that said, a program called VNC that is used to operate a computer remotely, over a network, has a menu option "Send CTRL ALT DEL" which causes the remote machine to display the options box. i think they may have used a low level keyboard hook of some kind though..

did a bit of research and it seems that ctrl+alt+delete is actually a special combination that, though some specific wiring in the keyboard, causes an interrupt to be generated on the cpu with a specific code. windows handles this interrupt and shows the security screen. how you would emulate this interrupt yourself, i do not know. might be good if you told us WHY you want to do this

Terminal Services doesn't allow me to do a CTRL-ALT-DEL 'across the wire'. The key combination activates the local terminal's security box.

I've tried fiddling with the settings of terminal services client but (thus far) to no avail. Of course, I might be missing something horribly basic - let me know if I am!

If there was an icon on the remote server's desktop that I run which "sends" CTRL-ALT-DEL that would be very useful!

Although, come to think of it, any program doesn't have to "send" CTRL-ALT-DEL, it merely has to invoke the "Windows Security" box. If it is known how to invoke that box, who cares about CTRL-ALT-DEL!
