Sikuli to unlock the computer

Try to regularly trigger events in your script (e.g. use Python module thread to implement it in parallel), that prevent that the machine locks.

Might have misunderstood your intention.

So if you want to catch the moment, when the machine locks and then unlock it and run a script:

you need a script, that watches the screen to realize it gets locked and then simulates the unlocking sequence.

RaiMan, I think what Justin means is in windows, you can lock you screen by press ctr-alt-delete.
and you need type in your username, passwoard and then press ok to go back to your desktop environment.
I tried to do the same thing but looks like once you lock the screen, Sikuli seems doesn't work anymore...

I am using winXP.

I think with comment #2 I understood, what he wants to do.

--- WIN-L is the standard key short cut to lock the machine, then the login screen comes up

--- if you have a Sikuli script running, when the screen gets locked, the script goes on running. But it will fail in the moment, you issue a find operation, since the screen does not contain the image, you are searching.

--- It is not possible, to operate on the login screen from the script running behind the curtain. click() and type() work, but do not have any effect. trying to capture a region with capture() seems to abort the IDE.

--- So one has to find another technique to get the machine to unlock, that can be triggered from a Sikuli script, that is aware of the fact, that the screen has got locked.

Is there an update with newer versions, where screen can be captured with a locked screen? Want to run the scripts unattended and for security reasons cannot leave the machine unlocked.

There will never be any solution for that with SikuliX (not possible with the concept).
SikuliX sees, what is visible on the screen.
