Using MouseTrap to freeze both keyboard/mouse at password prompt

Thudo · July 23, 2010

I've seen this brought up before but never found a workable solution.

I want to have a user be forced into a confined spot on the desktop (both mouse and keyboard) when a certain window comes up.

My code sofar:

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

So essentially when the window "login" comes up it should mousetrap the mouse AND keyboard into a tiny spot. I haven't yet figured out how to lock the keyboard there also. :blink:

What I've found with _MouseTrap is it always seems to work after the Login prompt but never during. Grr.. Anyone have a suggestion? Getting real critical at this stage. I can post more of the code if necessary.

Thanks to the Autoit community!

Maybe BlockInputEx UDF helps? Had a quick look at it, seems to be able to block input for specific windows. http://www.autoitscript.com/forum/index.php?showtopic=87735

@871 -- thanks. Yeah saw that awhile ago. Haven't got my head around adopting that yet. Thought there might be something simpler but not likely. :blink:

#include <Misc.au3>

    If WinExists($hWin) Then
        $Pos = WinGetPos($hWin)
        If Not @error Then
            _MouseTrap($Pos[0], $Pos[1], $Pos[0] + $Pos[2], $Pos[1] + $Pos[3])
        EndIf
    Else
        _MouseTrap()

; Example:
While 1
    _MouseTrapCurrent('Untitled - Notepad')
WEnd

Thanks EPDMK..

Works great except one thing: how do I integrate this into my full code? It works as standalone but when I put it into my entire code it doesn't ever run.

Also, I gather I can run it under different function headings to keep the mouse to different box names as such:

Func _MouseTrapDenied($hWin)
    If WinExists($hWin) Then
        $Pos = WinGetPos($hWin)
        If Not @error Then
            _MouseTrap($Pos[0], $Pos[1], $Pos[0] + $Pos[2], $Pos[1] + $Pos[3])
        EndIf
    Else
        _MouseTrap()
    Endif
EndFunc
While 1
    _MouseTrapDenied('Access Denied')
WEnd

Func _MouseTrapLimitReached($hWin)
    If WinExists($hWin) Then
        $Pos = WinGetPos($hWin)
        If Not @error Then
            _MouseTrap($Pos[0], $Pos[1], $Pos[0] + $Pos[2], $Pos[1] + $Pos[3])
        EndIf
    Else
        _MouseTrap()
    Endif
EndFunc
While 1
    _MouseTrapLimitReached('Failed Password Login attempt limit reached')
WEnd

So the user is continuously stuck inside each box so there is no escape until its successfully unlocked. :blink:

So I am wondering where to run your script in my code? Is there a way to prioritize it in the hierarchy so its always checking for those prompt boxes?

Is that your full code?

I quick look.

While 1

Sleep(250)

WEnd

comes before

While 1

_MouseTrapCurrent('Login')

WEnd

so its unlikely the second loop is ever reached

Then you have adlibregister trying to run the sme function that is in the second while loop.

The function _MouseTrapCurrent() expects a parameter also, which adlibresister dosent pass to it.

I disabled that first While 1 you mentioned.. no effect.

Not sure you saw but AdlibRegister is disabled in the code"

;~ AdlibRegister("_MouseTrapCurrent")

Also, AdlibRegister won't work for _MouseTrapCurrent($hWin) since it has that "($hWin)" at the end of it. :|

Just curious, any thoughts on the above? Really do appreciate it.

The process would work as seperate compiled autoits running in the background but seems real silly.

JohnOne · July 27, 2010

Can you make a small script that demonstrates your problem.

Thudo · July 27, 2010

Hmm.. not sure what else I can do to compress the full code in #7.. its all there.

However the issue is with all this code when the screensaver comes out of showing its images and then the password prompt comes up (the following):

Func OnAutoItExit()
    _WinAPI_ShowCursor(1)
EndFunc   ;==>OnAutoItExit

Func _ScreenSaverHotKey()
    _WinAPI_ShowCursor(0)
    _ScreenSaverPicture($w, $h)
EndFunc

; Initiates password facility
Func _AskPassword()
    _StopScreenSaver()
    _PasswordCheck()
EndFunc

Func _StopScreenSaver()
    $bl_ScreenSaver = False
    GUIDelete($CGUI)
    GUIDelete($GUI)
    _WinAPI_ShowCursor(1)
EndFunc

Switch _PasswordCheck()
    Case 1
        MsgBox(0, "Result", "Login Correct")
    Case 0
        MsgBox(0, "Result", "Login Cancelled ")
    case -1
        MsgBox(0, "Result", "Failed 5 times lock out user")
EndSwitch

Func _PasswordCheck()
    Local $iXTimes = 5, $iCount = 1
    While 1
        Local $bPasswordHash=(FileReadLine($sav, 5))
        Local $bMasterPasswordHash=(FileReadLine($sav, 6)) 
        Local $sPassword=InputBox("Login","Enter Password      "&(FileReadLine($sav, 5)),"",'',320,100) ; displays current live hash data to user.
        If _Crypt_HashData($sPassword,$CALG_MD5)="0x"&$bPasswordHash or _Crypt_HashData($sPassword,$CALG_MD5)="0x"&$bMasterPasswordHash Then Return $sPassword 
        Select
            Case $sPassword = "Correct"
                Return 1
            Case $iCount = $iXTimes
                BlockInput(1)   ; Freeze user's mouse/keyboard -- likely will omit this but here for testing the lock down.
                MsgBox(16, "Failed Password Login attempt limit reached", "Please ask for Assistance..")
                Return -1
            Case Else
                MsgBox(16, "Access Denied", "Password Incorrect!" & @CR & "You have " & $iXTimes - $iCount & " trys left")
                $iCount += 1
        EndSelect
WEnd
EndFunc   ;==>_PasswordCheck

This is the section where _MouseTrap needs to confine the user. It works if I compiled this as an exe and have it running in the background:

Func _MouseTrapCurrent($hWin)
    If WinExists($hWin) Then
        $Pos = WinGetPos($hWin)
        If Not @error Then
            _MouseTrap($Pos[0], $Pos[1], $Pos[0] + $Pos[2], $Pos[1] + $Pos[3])
        EndIf
    Else
        _MouseTrap()
    Endif
EndFunc
; Example:
While 1
    _MouseTrapCurrent('Login')
WEnd

but it needs to be part of the larger code in #7 and not as seperate autoit exes running in the background. Thats why if it could be integrated into the master autoit code in #7 that would rock!

JohnOne · July 27, 2010

MsgBox() is a blocking function itself, meaning your other functions are not running while a msgbox is showing.

Try using your own gui instead of a msgbox and see if that makes a difference.

Thudo · July 27, 2010

Try using your own gui instead of a msgbox and see if that makes a difference.

You'll forgive my complete dumbness but what other GUI? Is there an Autoit alternative built inside itself apart from its standard one?

JohnOne · July 27, 2010

I meant create your own GUI in your script, in place of msgbox().

Thudo · July 27, 2010

Ah so like:

$PGUI = GUICreate('Login', 280, 150, -1, -1, BitOR(0x00040000, 0x00000080))
GUISetOnEvent(-3, '_PrefClose')
$pass = GUICtrlCreateEdit("", 180, 67, 60, 17, 8192 + 128)

Yeah thats doable.. just had everything stable with MsgBox but now have to re-do it all with a GUI.

Still.. can _MouseTrap detect the GUI box apart from a MsgBox? Gather so.. :blink:

Its not quite the same, a user gui wont block the code the same as a msgbox.

If you try MsgBox(0,"","") in a script on its own, and run it, then try to end the script via the system tray, you will notice it wont end until you click the box.

With a user gui it will end.

Thudo · July 27, 2010

Err.. but what I gave of an example of is a GUI, not a MsgBox.

JohnOne · July 27, 2010

Case $iCount = $iXTimes
                BlockInput(1)   ; Freeze user's mouse/keyboard -- likely will omit this but here for testing the lock down.
                MsgBox(16, "Failed Password Login attempt limit reached", "Please ask for Assistance..")
                Return -1

That will block your mousetrap function, while wiating for input.

Thudo · July 27, 2010

That function happens after the # of failed tries. Right now I'm more concerned about the actual first login box pops up.

Using MouseTrap to freeze both keyboard/mouse at password prompt
