How to enable Windows Lock?

[chyrl]

I am developing a system to enable Windows Lock on platforms (XP and Win7).

For example, I want to lock the computer's screen using Java?
Is this possible? If I am going to use JNI?
What methods I am to utilize using C/C++ native library?

Thanks.

Locking a computer (or its screen) is not an application's task. Of course there's some vague API available in MS Windows so you can try the JNI route but I find it a strange functionality. Why do you people want to implement those preposterous functionalities anyway? Just for kicks? It is a system functionality. I can hardly wait until someone comes in with hardly any computer knowledge at all who wants to do it remotely (from a cell phone preferably).


kind regards,

Then count me as one.
I am trying to do develop a CyberCafePro like system using Java as it's programming language.
