[same topic maybe] CTRL + ALT + DEL

6 posts in this topic

Hi guys..

maybe already discussed in another thread, and I already searched both in google and this forum, but still can't find what I want :D

I'm searching the coding to press CTRL + ALT +DEL. Does anyone know?

my purpose is not for task manager.

in office,, my PC always automatically lock after 10 mins idle (don't suggest me to disable this automatically lock feature,, since I don't know admin password :D ).

in the midnight, I have to run some program. but before that, I need to unlock the screen.

The only way to unlock is pressing CTRL + ALT + DEL and then enter a password.

that's why I need to know the coding to press CTRL + ALT + DEL in autoit.

or anybody have another idea?

thanks in advance :)

From the help file for the Send command.

N.B. Windows does not allow the simulation of the "CTRL-ALT-DEL" combination!


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Yep, autoit cant emulate it, Actually no language can.

Here's what vnc does:

BOOL
vncService::SimulateCtrlAltDel()
{
    vnclog.Print(LL_ALL, VNCLOG("preparing to generate ctrl-alt-del\n"));

    // Are we running on NT?
    if (IsWinNT())
    {
        vnclog.Print(LL_ALL, VNCLOG("spawn ctrl-alt-del thread...\n"));

        // *** This is an unpleasant hack. Oh dear.

        // I simulate CtrAltDel by posting a WM_HOTKEY message to all
        // the windows on the Winlogon desktop.
        // This requires that the current thread is part of the Winlogon desktop.
        // But the current thread has hooks set & a window open, so it can't
        // switch desktops, so I instead spawn a new thread & let that do the work...

        omni_thread *thread = omni_thread::create(SimulateCtrlAltDelThreadFn);
        if (thread == NULL)
            return FALSE;
        thread->join(NULL);

        return TRUE;
    }

    return TRUE;
}

Easy way would be to prevent locking by moving mouse after every 5 minutes.

If you work with sensitive data, it's a good way to get fired. Believe it or not there is such a thing as corporate espionage, and a somewhat common vector is the cleaning person. I.T. doesn't piss people off, just because its fun too.

A better way would be to figure out how to process whatever you are doing via command line or scripted data manipulation.

could you explain me what vnc is? is it the coding used in autoit, too? *I'm not too familiar with programming

I don't prefer moving mouse every minutes. All my job is related with sensitive data. Just what DicatoroftheUSA said below, it's easiest way for me to get fired :D

thedoe,

I too have access to a sensitive network which locks my machine after 10 minutes and I am not at all happy about any discussion on how to beat that. Particularly as you will still have to enter a password and the Forum Rules prohibit discussion of such things on the forum. So I am locking this thread. :naughty:

My advice would be to talk to your system admins - if you have a valid reason for running that program they should be able to help. If you do not....... ;)
