Locking Computer

[MIchaelfjsmith2]

does anyone know if the following command has been blocked from use

Send("#l")

I am trying to have a script lock the screen but am having no luck. Does anyone have an alternative solution.

Thanks,

ShellExecute("rundll32.exe", 'user32.dll,LockWorkStation')

You could also use _WinAPI_LockWorkStation.

Which I believe uses the same dll (correct me if I'm mistaken, someone who knows)

[MikahS]

You are correct JLogan

Thanks guys both worked great. Would either of you be able to tell me how i could unlock it by autoit also?

Thanks,

You cannot.

Think about what you're asking for, then see below. "To unlock the workstation, the user must log in"

Yes i understand that. What i am trying to accomplish is. I have an autoit script running on my computer that looks for a specific file on a usb stick. so when that usb stick is plugged in if it has that file it will login for me. when i unplug it the computer will lock. i have the script functioning properly when replacing the lock/unlock with a run/process close.

It is my understanding that the process of login cannot be automated.

Anything's possible though.

What you're talking about is two-factor authentication - which I doubt you're going to accomplish with an AutoIt script on a USB.

I know what you could do....Have a script running that puts up a splash screen that fills the entire screen. The only way to hide it is to put in your USB stick. WHen the script sees the stick, it hides the splash screen. You remove the stick, it puts the splash screen back.

This is not 100% secure for CTRL-ALT-DEL can close the script but you have to know what your doing.

May I ask however - why not simply use the Windows key +L to lock the workstation when you leave the workstation and then use your password to get back in when you come back. Pretty much everyone else does that and it works great.

[Bert]

IF you do not want to type in a password, get a fingerprint scanner. Touch the scanner and you are back in. Easier than plugging in a USB flash drive and you won't lose your finger...unless you cook, or use a chainsaw, or play with knives....

Better yet, get a badge with a proximity sensor. All you have to be is within 5 feet.
