Enhancing AutoIT ScreenSaver Example

Thudo · June 23, 2010

Thanks to the AutoIT community..

Essentially what I need coded/integrated into that is as follows:

1) Based on a setting in the screensaver.cfg, to determine inactivity to then enable the picture screensaver.

2) Enable the screensaver using a HOTKEY combo (our WINDOWS keys are non-functional so we need other key combos)

3) Password protect the screensaver so when it comes out of the picture slideshow it asks for a password (this password is stored in screensaver.cfg and locally in registry *in case location where the .cfg is not available*). Note: we don't password protect our desktops hence the need for #3.

4) Backdoor password access.. one that doesn't change the password set. In the past we use a decimal to octal conversion routine: The title bar of the password box has a random number, that if you type it into a calculator and hit the OCTAL button, then type in the octal equivalent into the password box it unlocks. This is not a password or function our desktops use or understand exists, but we know what to do. ie. If we type in "53824" and hit the OCT button, the result is 151100. If you type that in the password box, or the actual user password, it'll unlock.

5) When Screensaver is active, it must be able to allow forced shutdowns and restarts from outside sources/processes such as, for example, desktop updates.

So any coding help on these would be massively appreciated! The above are the most critical features to be added.

Thank you AutoIT Community!!

Many people would be happy to help you, but we aren't here to just make custom programs per your request. If you attempt to do what you want on your own, you can come to us if/when you get stuck.

I recommend reading the helpfile too.

Thanks Paulie.. sorry I need to take this slowly then..

Ok my main problems having edited the code are as follows:

1) I've added a 4th line to the cfg file for idle time outs. When I try to call it the screensaver simply keeps running and I have to end-task it. Not sure whats wrong. Notice this under "Func _IdleTicks()" which has been edited.

2) I still have yet to figure how to use _MouseTrap when then "password box" comes up -- essentially I have tried to freeze the screen around the password area but doesn't work. No sense in having the user unlock the screensaver when they can use the windows behind the password box.

3) Storing the password to unlock will be the 5th line -- you'll notice there is now an "Func _AskPassword()" now but how to relate to that 5th line so it will check the cfg file for that password and when the user types the right one it unlocks it -- this part I have no clue.

4) Anyone recommend a proper "password box" where a user can type the password into it? I'm still learning GUI structure.

Here is my updated script:

Ok I think I got #3 and 4 sorted in the list. Using an MD5 Encryption and storing the hash in the cfg. GUI box works well for what it is.

I'm still a little dumbfounded with the _Idleticks and _MouseTrap functions.

For Idleticks it was suggested to use this to determine how long to wait to bring up the screensaver when no activity was determined:

Func _IdleTicks()
;~  ;Dim $i_WaitIdleTime = (FileReadLine($sav, 4)) ; 10*1000 ;=10sec (ms) // only for example then you will read this value in the config file
    Local $h_GTC = DllCall('kernel32.dll', 'long', 'GetTickCount')
    Local $i_Ticks_Init = $h_GTC[0]
    Local $struct = DllStructCreate('uint;dword')
    Local $i_WaitIdleTime = (FileReadLine($sav, 4)) ; 10*1000 ;=10sec (ms) // read from value in the config file
    DllStructSetData($struct, 1, DllStructGetSize($struct))
    DllCall('user32.dll', 'int', 'GetLastInputInfo', 'ptr', DllStructGetPtr($struct))
    Local $i_TicksSinceIdle = DllStructGetData($struct, 2)

    If ($i_Ticks_Init - $i_TicksSinceIdle) > $i_WaitIdleTime Then
        MsgBox(64, "", "Now we can start the screensaver")
    EndIf
EndFunc  ;==>_IdleTicks

But if I use that then the screensaver never brings up the password box and just stays at a black screen. "(FileReadLine($sav, 4))" is set to read the 4th line of the cfg so its set to 10sec.

As for the MouseTrap so it freezes the Password screen so only the user can type inside the box.. this code was suggested:

Func _MouseTrapCurrent()         
    Opt("MouseCoordMode",0)         
    $local = MouseGetPos()         
        _MouseTrap($local[0],$local[1])         
    Opt("MouseCoordMode",2) 
EndFunc

..however where does it go?

The Password box comes up using this function:

; Hash Password check facility
Func _PasswordCheck()
$bPasswordHash=(FileReadLine($sav, 5)) 
$sPassword=InputBox("Login","Enter Password.","")
If _Crypt_HashData($sPassword,$CALG_MD5)=$bPasswordHash Then
Else
    MsgBox(16,"Access Denied","Password Incorrect!")
EndIf
EndFunc

Any help is most appreciated!

This ~~AutoIT~~ versus AutoIt use seems to be very contagious ... or maybe it only seems to be that way ... :blink: (Re-Filing it to ignore cabinet.)

hehe... yeah sorry.. Autoit.. AutoIT is an oxymoron. :blink:

So my question apart from the _IdleTicks above..

How do you use _Mousetrap to lock the user inside a current window? ie.. I have a password box called "Login" which comes up and I want to freeze all mouse/keyboard to inside that box until the password is correct. Not worrying about Ctrl-Alt-Delete currently right now to unlock (although is that even possible to prevent as well)?

Thanks everyone..

Ok at a crossroads here and really need the autoit community on this one:

1) Code for determining when the screensaver should show the images after being idle for a determined time:

Func _IdleTicks()
;~  ;Dim $i_WaitIdleTime = (FileReadLine($sav, 4)) ; 10*1000 ;=10sec (ms) // only for example then you will read this value in the config file
    Local $h_GTC = DllCall('kernel32.dll', 'long', 'GetTickCount')
    Local $i_Ticks_Init = $h_GTC[0]
    Local $struct = DllStructCreate('uint;dword')
    Local $i_WaitIdleTime = (FileReadLine($sav, 4)) ; 10*1000 ;=10sec (ms) // read from value in the config file
    DllStructSetData($struct, 1, DllStructGetSize($struct))
    DllCall('user32.dll', 'int', 'GetLastInputInfo', 'ptr', DllStructGetPtr($struct))
    Local $i_TicksSinceIdle = DllStructGetData($struct, 2)

    If ($i_Ticks_Init - $i_TicksSinceIdle) > $i_WaitIdleTime Then
        MsgBox(64, "", "Now we can start the screensaver")
    EndIf
EndFunc  ;==>_IdleTicks

The above basically causes the screensaver (I'm not compling it at this point just running it from Autoit) to not respond to the mouse to bring up the password. It just goes to a black screen and stays there. Whats the problem?

2) I'm understanding _MouseTrap now except no idea why it won't enable when the password box comes up to confine the user there.

Basically trying to get this code to work when the "login" box comes up but never works except after it.

AdlibRegister("_MouseTrapCurrent")
Func _MouseTrapCurrent()
If WinExists("Login") then
_MouseTrap(550,500,750,600)
else
_MouseTrap()
    endif
EndFunc

If you want me to post all the code I will in-case something is not clear.

I feel I'm getting really close with the whole project just making additional refinements which satisfy the security team.

Thanks everyone!
