    Also added auto-unlock on putting the cable back in. However as discussed above, this could cause issues with GPOs, so will need to look into this, or just don't allow auto unlock

    New version should be up in a minute :P

    Also FN-GM what bit of UI were you referring to? Know its pretty basic currently, but not sure what bit you actually mean :P Is it admin side? whole thing? or what

    Steve
    Admin side, whats that? not seen it.

    I am just not keen on the lock screen to be honest.

    Also it would be nice to be able to set your on Text on the lock screen.

    Aye, Any plans on what you'd like on lock screen? :P Originally was going to just be blank with writing, but seemed little boring

    And yes, can set it so you could set text, again though need to decide how it's laid out first :P

    I would like to see something brighter.

    Maybe a picture of a padlock? Or a stop sign? an unplugged network cable?

    Something i would say is do not brand the lockscreen with EduLock. They will see this. They may google the software, find it and play around with it and find a way round it.

    Cheers

    Aye valid point. Think I'll end up making few options of screen etc.

    Already redone a large part this afternoon, Changed it so you can choose if you want teachers to unlock, auto unlock, choose passwords, and written text etc. Aswell as changing the bits so admin password disables the "relock if disconnected" part etc

    Just need to fix one thing I broke, and will make a few options for screens, and throw a new copy online tomorrow sometime.
    (Still not sure if there's an easy way to check if GPOs applied without making the admins input a list of GPOs, which isn't very good way :P)

    Thanks

    its a good idea, i like it, but you need to obfusicate your source so its not so easy to decompile


    string s = "You've been locked due to network cable disconnection!";
    g.DrawString(s, font, brush, (float) ((((double) this.Width) / 2.0) - 10.0), (float) ((((double) this.Height) / 2.0) - 20.0), format);
    string str2 = "Please get a teacher/admin to unlock!";
    g.DrawString(str2, font, brush, (float) ((((double) this.Width) / 2.0) - 10.0), (float) ((((double) this.Height) / 2.0) + 20.0), format);
    int num5 = width;
    for (int i = 0; i <= num5; i += 7)
    {
    g.DrawLine(pen, 0f, i * num3, (float) (width - i), 0f);
    this.BringToFront();
    g.DrawLine(pen, 0f, (width - i) * num3, (float) (width - i), width * num3);
    this.BringToFront();
    g.DrawLine(pen, (float) (width - i), 0f * num3, (float) width, (width - i) * num3);
    this.BringToFront();
    g.DrawLine(pen, (float) (width - i), width * num3, (float) width, i * num3);
    this.BringToFront();
    }
    this.TextBox1.Focus();

    The problem with all that sort of stuff, is it doesn't make it harder to decompile. Only to understand.

    I mean, take simple:

    int test as string
    test = "Hi" + test
    Sure you can make it stupidly long, hard to know what it does variables,

    int AIWOTNAIOWHTIOAWTHANW as string
    AIWOTNAIOWHTIOAWTHANW = "Hi" + AIWOTNAIOWHTIOAWTHANW
    But end of day it's still exact same code. Unless I'm missing something :P

    Aye, but C can be decompiled too if you have the programs. As with everything, it's kind of, time vs worth :P

    But guess I'll see once I get more completed version :P

    Thanks,

    i know what your saying mate,

    we actually encourage the use of .net decompiler for students to learn,

    c/c++ compilation is a whole different ball game, are they any that will actually spit c/c++ source back out or do they all give asm


    don't get me wrong, I wasn't trying to discourage you, I think its a great idea and will be looking at it monday,

    on seconds thoughts keep it .net and I can make my own moded versions

    (Anyone know why I can't edit my first post anymore? Is there a limit to edits or something silly? O.o)


    New version up:

    EduLockv3.zip

    Changes:
    • Changed default lock screen to a "light" covering of their normal screen.
    • By default the program has a notify Icon (bottom right taskbar), that can be used to access admin page
    • Can choose wording to be shown, including multi-line
    • Can change admin login, admin unlock and teacher passwords (Currently NOT saved between sessions)
    • Can testLock the program from admin screen (Saves unplugging )
    Should fix a few issues, "imo" a much cleaner lock screen.

    Three passwords currently are:
    Teacher Unlock: test
    Admin Unlock: test2
    Admin Console: admin

    As mentioned, all changable currently, "but not" saved between sessions.

    Can choose if teachers can unlock, if you want autounlock, and if icon shows (Idea being you hide it once admin first sets options, Which "will" save)

    So yeah :P Any opinions on changes/If i missed something etc etc.

    Things to do still:
    • Save settings between sessions
    • Hide passwords
    • "Once" complete, remove debug kill switches!


    Any other suggestions etc, Still gratefully accepting

    Many Thanks,
    Steve

    Auto Unlock seems good.

    Much quicker in pickup up the disconnected cable.

    How do you get into the admin console?

    Problem found.

    As i said before. If i disconnect during logon it will lock the machine. But once i reconnect it auto unlocks. Then the user has full access to a machine without any group policies.

    Also when i log off i get the attached

    Also when i right click the icon in the system tray there are no options the menu is empty
