 Posted: Tue Jan 15, 2008 4:08 pm Post subject: Locking the computer |
 |
|
This is a script I made to lock the computer using a password so no one will work on it while I'll be out. Don't worry about the variable/subroutine names. I first wrote the program in the Romanian language ('cause I'm Romanian  ) and I translated only the strings after that.
| Code: |
#NoTrayIcon

gui,2:destroy
gui,destroy
Gui, Font, S8 CDefault, tahoma
Gui, Add, Text, x26 y20 w80 h20 ,Name:

else

PS:If you didn't inspect the script, then, after the screen turns black, try to access Task Manager (via Ctrl+Alt+Del) and see what it happens.  |

 I try it. Just press Ctrl + Esc (to Start menu) or simple the Win button... So... Alt + Tab is works to... But I run it with administrator privileges...
Okay, I understand! I can not kill it, BUT I can use the computer! 
But... There is a simple hack:
- Click to unlock
- Type an incorrect password
- Click to enter
- Do NOT click OK.
- Press Ctrl + Shift + Esc
- Kill the AutoHotkey
- Enjoy.

Oh! I have no idea about how to remap the Win key because my keyboard is an old one, which hasn't got any Win key!  |

also holding the winkey and r then typing
cmd
then from command prompt
taskkill /f /im autohotkey.exe ends it irregardless
sorry but short of actually locking the pc this is without a point
also alt + f4
just lock the pc and get it over with why even bother with this???????????

no no thats not what we are saying
we are saying that its a nice idea but you cant use a user run script to give you protection that is better implemented in windows
i aplaud you for the effort i wishe every one would read the documentation and forums and try things like this

I concur with Tank. It is an interesting idea, some of which I might be able to apply to some of my locked down workstations in the lab. It is always good to have a goal in mind to try to code for. Keep coding! Don't give up.

| I personally have a similar script that I modded. It turns the whole screen black, and you have to put in the right password to show it again. I also blocked winkey r, winkey l, ctrl shift esc, and other such commands. It defeats all but the most computer literate, which aren't much around here. The reason I wanted my own was so I could still use my hotkeys to control winamp and such things, without having to enter my password. |

the point is that it wont stop anything that win +L
also no one is saying not to keep trying ideas these attempts no matter how faulty the idea may be the ability to write successful scripts will aid you when you do finally get that really good idea. your experience with bad ideas well implemented will give you excelent coding skills for the really good ideas
beleive it or not the thing that separate sean and majkinator for instance from this. is that they post the code they find to be a really good idea. i garantee they write p-lenty of pointless scripts that they themselves find novelty in. and this is what makes them great programers

| So I have no ideas about how to improve it (maybe because I'm tired). Can someone help me? |

Do not try this  You can kill it only with reboot. (Or log in as a different administrator) Sorry my english.

well first we need to clearly define your goal
0 create a gui to save user and pass combo in variables
1 remove interactivity of input devices
2 require specified key combo to activate a password prompt
3 store a set username and pass combo
4 verify user and pass combo after specified key combo
5 exit gui on successfule user pass combo and release access to input devices
6 go back to locked screen on failed user pass combo
we might make these each functions and test them separately
then experiment with putting them together
