full screen, always on top form, shouldnt be closed by users?! any idea?

[persianboy]

hi,

how can i disable ctrl+alt+del from my form, what i want is to have a full screen , always on top form, and users shouldnt be able to end task it or kill the process, my problem is in the last part, where i think disabiling ctrl+alt+del is the solution, so how can i do that, or is there other ways from preventing users from shutting the prog. down?!!


thanks,

setting the forms , show in taskbar property to false , removed the program from the application tab in the task manager, but users can still shut the process down, what can i do about that?

[persianboy]

guess we cant do anything about the ctrl+alt+del ( since were using win2k ) from within the program , but the admin can disable the task manager for us

there IS a way for sure, so keep looking. i used to know this guy who programmed a similar thing for a local network-gaming place. once user logged in, it only showed this one full screen interface, requiring username/password then game choice, but u could never exit the program or view desktop. but that was done in vb 6.0 and the guy is in another country now.
anyways, keep ur hopes up.

i'm doing almost the same thing, its a program for an internet lab! do you remember if that friend of yours program used to run on a windows2000 computer?

I've seen a post in VB6 section that were asking about disabling Alt+Ctrl+Del specifically in W2K and the guys there did find a solution .Do a search hopefully you can find it .

i read that a couple hours ago, but they couldnt do it for win2k!!

[ramezb84]

hello once again,
i'll call the place tomorrow and ask what windows they are running, i believe it is windows 2000. not sure though. will post again tomorrow less i forget.

[persianboy]

that would be wonderful, i'll check the thread tomorrow, thanks

You can disable the Task Manager

But I don't think you can disable the Ctrl+Alt+Del functionality completely, at least not in Win2k+.

If this is for an internet lab... the administrator can disable Task manager and a bunch of other stuff through the Administrative tools and the Registry for each computer (but not for users marked as Administrators).

i guess its the best thing to do, now that we cant do anything in code

I don't know if this will work or not

Using wide system hotkeys comprises Ctrl+Alt+Del then just assign your app to launch when these combination are pressed and make it ontop of Task Manager . Do you think this will work ?

[persianboy]

i dont think thats possible , the best solution i came up with so far ( not usign admin privalages ) is to set our form to full screen, no toolbar, and put a timer to set the topmost property to true every second, even though the task manager can come on top of our form, but it would only stay for a second

[Pirate]

Before you use timer (since I believe it consume some resources), try using this event . For me it works good :

Private Sub Form1_Deactivate(ByVal sender As Object, ByVal e 
As System.EventArgs) Handles MyBase.Deactivate
'Use this member function
        Me.TopMost = True
 
'Or use the API Showtop most instead 
End Sub

[persianboy]

your code is much better, i used the timer since i already had it for some other use
