Computer Lock: Another VB Project by Navigator256

[TheBigDolphin1]

Nice one, but Control+Alt+Delete can be used to open task manager. And Alt+F4 would close it.

[navigator256]

@TheBigDolphin1 Thats just what's so unique with this program! You cannot quit or open Task mgr. Only it seems like Windows 7 doesn't work anymore, so use either XP or Vista. I'm working on a patch for Windows 7.

[TheBigDolphin1]

@navigator256 Yeah, I know, I have just downloaded it to test it.

I like the fact task manager doesnt work and stuff like that, but on VISTA/7 you can lock the computer anyway.

P.S. you can press ALT+F4. The only problem past that is getting things to show up. but open documents show. :)

[Habbsurf]

it didn't protect...

[thescaryscreamers]

why I press CTRL + ALT + DEL, the task manager is opened

[navigator256]

@thescaryscreamers Weird, what OS are you using?

[thescaryscreamers]

@navigator256 new version of windows 7.

[sharperner35]

Such an easy code!

[navigator256]

@sharperner35 Not really. Try disabling Ctrl Alt del, Alt Tab and Windows key with VB! Good luck ^^

[megaman351000]

@navigator256 you forgot CTRL + SHIFT + ESC

[TheCoeckiefication01]

@navigator256 Top most would solve the tab and windows key. ctrl alt del can be stopped with process killing That to do when he tracks the process. (taskmanager) to track it, use a timer (1000 interval) with the following code: public class form1 dim process as process() for each process in process.getprocesses if process.tolower.contains("task­") then system.diagnostics.process.get­fromid(process.id).kill() end if next Something like that ^-^ You can work it out for yourself i guess :O

[TheCoeckiefication01]

Alt F4 can be stopped with using the button down event.

There you will be able to put something like

if e.keycode = keys.F4 then

application.restart()

end if

If it sees that you press F4 (with any other key) then it restarts the application.

not the best solution, but still good.

For example, you could let it make a state file, so when it restarts it goes to the state it was in (configs) when you "closed" it, so it looks like it was never closed. Apart that your window dissapeared for a sec. :D

[navigator256]

@TheCoeckiefication01 Not really, if I press Alt + F4 it won't restart the app, because that would mean people have to enter their password that they want to use to lock the computer again, so it would be too easy to get out. I'm sorry, I don't have the original source anymore, but the taskmgr.exe was not even opened when you pressed a Ctrl alt del...

[TheCoeckiefication01]

@navigator256 Well it is the purpose of goign to ctrl alt del? no? So if you want to try to get in you use task manager ._. Since it will be killed you can't try. If you want to log out, no meaning either since you will need a password.

i disabled the ALT+F4 function if used this

Make 2 the same form's.

If form1.close then form2.start.

so if somebody exit the locker.. another screen loads automaticly...

look at my simple example project...

[kosata6]

Please lock code on the screen:)

Please

[gookmail]

my mistake it's Alt F4 :P trying to figure how to disable that :l

[navigator256]

Alt F4 is also disabled..

[navigator256]

Hahha.. Its just coding.. Good coding :+).. Anyway the program is available at my website: check the link in description

[gookmail]

yeah i know i think i know how to do..

[gookmail]

im very sorry to say this but you can alt tab out and open another of this then set your own password then use the password you set to unlock everything.. lol hahas but great job..

Heres a tip to disable alt tab

Timer1

Interval > 1

Enabled > True

Code for timer1

Me.topmost = True

[w2010rcdas]

@gookmail

thx but alt F4 and ctrl alt del still work

[peterisannoying]

how do you block the keys?

[navigator256]

By using the command KeyHook and then (hooking keys means checking if checked) disable the keys you want to be 'hooked'.

[peterisannoying]

Iv never herd of that, help? (Im a begginer, iv got it so it come up but you can close it with alt+tab or CtrlAltDel)

[navigator256]

Try searching a VB Forums, it's been a while ago I coded this.

[1337TNTX32]

damn thats easy to do... I would like to see the source though... i'm interested in making programs unclosable...

[Pvsmuntje]

You could make a form as big as your screen, so it covers your whole screen, and makes it unclosable except for the task manager.

Or you can go to the form event "Form_FormClosing", and type:

e.Cancel = True.

Which cancels the event FormClosing.

Hey dude, how about this... find the code for enabling the keys and add an extra code line to the button. Add in the enabling code so that it enables the keys if the text in the password box is correct. It should be simple, if you can find the enabling code. Since you already have the disabling code, it should be fairly similar. Good Luck and pm me if you get it :)

[navigator256]

I think i've already implemented this in my project. When you unlock, all keys are enabled again.

[mysteryloser24]

Oh well thats good then :)

[themrcomputergeek]

well how do you make the program?

[navigator256]

How do u mean? I make it with VB2008, if u want it, pm me =)

[LiamGiles94]

cool whats the song

[navigator256]

oh wait i got it here Revenge - Plain White T's

[LiamGiles94]
