For WIN OS professionals only, help needed?????????

Post by mld »

Hi all
i am a student in IT institute

i am developing my graduation project
its a program named desktop locker

I am alone, no supervisior and no one to help me.

my problem is that i dont know, what OR how to do that
i will tell you what i have did, and plz plz plz.
give me your opinion and advise

when my program lock the computer it does:

1- lunch Topmost form with full screen,no borders
2- it listens to move and resize MSG's and it prevent them
3- it makes a timer that will make my program on top every 1 milie second, and it checks if the active widown is from our process or not

4- it blocks all the (alt or ctrl or win) keys
5- it blocks the shutdown operation, un less it is forced
6- it blocks the minimze command even if it used by code like shell.minimizeall
7- it blocks the autorun on the CD ROM
8- it blocks the task manager form the registery
9- it listens to WM_SHOWWINDOW msg, and if it is hide, it will start a timer after 1mili sec to show my form, i did like that because i couldnt prevent the hiding operation
10- i make a dynamic class name for my form, this will change the class name for my form every time i lunch the program
11- hide the taskbar
12- disable and hide the desktop

i think that is all what i did to prevent any one to use the computer, unless he unlock it with a password

iam not sure if this is a good way or not.
give me opinions and advises
iam alone
help me
i need a profesional opinio and advice
and any one,any one who has an idea, plz tell it to me

The better way would probably be to create an additional desktop. At least that's how the XP/2003 internal "lock computer" functionality works like.
