    Because Win9x sucks! And we enjoy programming, not just playing games. I want to know!

    if you know...

    You probably can't. Not on my school's network. They register it as a service so it is hidden in ctrl-alt-del.

    The way around it, make a new text document in your work area, rename it to "hello.html" or anything ending with .html

    open the file and edit the source to the following:

    Code:
    <HTML>
    <BODY>
    <IFRAME src="c:\">
    </IFRAME>
    </BODY>
    </HTML>
    yay! you're on the C drive. Now you just have to hunt down that program and delete it, then reboot. On our systems it is in C:\Program Files\RM and it is called "WindowGrabber.exe". I also made a program which removes the restrictions from the registry [so i can use the dos prompt and run commands] with some code I scooped up from this board.

    Systems with restrictions are the funnest things in the world.

    oh and they have this new trojan-style program on our network which takes screenshots of what you are doing so they can see. to keep my emails from a certain girl out of their sight i am working on a program to figure out what port the program uses, and then another to block the port.

    It used to do a pop-up asking you what your name was, so it could associate you with your screenshots. You could make the client program crash by b/o'ing the text box with unicode characters *shrug*

    Hehe, I wonder.

    I also want to know how to make it so that they can't click Shutdown, can't press the reset or power button, can't unplug it, and can't leave the room. Any ideas?

    Programmer: I think you forgot; Power outtages can't affect the computer running and they can't trip the circuit breaker (although I guess if they can't leave the room they can't do this either unless the circuit breaker was in the same room).



    There is only a couple good uses to stopping ctrl+alt+del, one is for games like Ultima Online or EverQuest to stop the users from running outside programs to help them cheat their characters. Another is in security programs to stop users from completely shutting the security software down. Although, as some have posted, there are a million and one ways to get around these programs. Most of them anyways. There are a few out there that do provide better security, but there are always going to be loop holes for those who know how to look.

    As for stopping the ctrl+alt+del key combination, I will check it out and reply with whether or not I have found a way of doing it or not. It shouldn't be too difficult.

    According to NeHe's tutorials, this stops a screensaver:
    Code:
    case WM_SYSCOMMAND:
    
    case WM_SCREENSAVER: //i think that, or maybe SCREENSAVERSTART
    
    return 0; //this stops it from starting
    
    break; // end syscommand..
    maybe you could make CTRL + ALT + DELETE Do something different.. or just check and see if they were pressed and then break;. That way nothing would happen. I am not sure how to check and see if you press it in the WinProc though... sorry.

    >Fortres

    My school runs fortres so that the users can't screw anything up. It is useless though, one way around is to open IE or Netscape and type C: as the address and that gets you in. As far as I know, Fortres can't be disabled by Ctrl+alt+del. You have to actually know the password, but I may be wrong. I'll check tomorrow.

    guess they should get rid of IE then or put the disk drives as restricted sites or something...
