    Question Doing CTRL-ALT-DEL

    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,

    Mark

    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..

    Re: Doing CTRL-ALT-DEL

    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

    Re: Doing CTRL-ALT-DEL

    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!

    Re: Doing CTRL-ALT-DEL

    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!

    re; terminal services

    i read that you use Ctrl+Alt+End when using TS, if you want the security box to appear on the remote machine. Ctrl+Alt+Del triggers the local one

    I also recall reading on microsoft web site that the key combination is AltGr+Del to trigger the remote box (when under ts)

    Re: Doing CTRL-ALT-DEL

    Although it doesn't work for me it seems that there is a way to trigger the "Windows Security" box. Have a look at http://www.codeproject.com/system/al...rol_delete.asp. (it's in VC++)
    If you just want to call the Task Manager than it's simple 'cause you can use Shell to execute taskmgr.exe from windows\system32.
