Using non system variable with WMI

Recommended Posts

TMelanson

Hi folks,

I'm hoping someone can help me out here.

Background:
I have the need to run a program with admin credentials (#RequireAdmin), and then get the SID of the locally logged in account. Not the admin account.

If you look at the attached script, Line 16 uses the @UserName variable and returns the SID for the admin account I used to launch the app.
I want to use line 17 which passes the result of the _GetUsername function which is a username using  ($UserName) to the WMIService.

I'm getting " The requested action with this object has failed.:" error message.

Any suggestions would be appreciated! :D

I'm no expert with "winmgmts", but i can say the reason why the object fails, is the method "Get" with your properties is throwing an exception. And AutoIt does not work well with object exceptions, without catching object events.

I would think the code below MIGHT be a solution.

MsgBox(0, "", _Security__SidToStringSid(_Security__GetAccountSid($UserName)))

otherwise something like this:

$objAccount = $objWMIService.ExecQuery("SELECT SID FROM Win32_UserAccount WHERE Name='"&@UserName&"'"); i use @UserName, as the return from "_GetUsername()" contains string terminating char(s) and makes the query fail.
For $row in $objAccount
    ConsoleWrite($row.Name&@CRLF)
    ConsoleWrite($row.SID&@CRLF)
Next

 

Anyway, i hope some of this will be helpful.

Here is a way to get the list of logged on users (from the registry)  :

#RequireAdmin


#include <Security.au3>
#include <Array.au3>

Local $aLoggedOnUsers = _GetLoggedOnUsers()
_ArrayDisplay($aLoggedOnUsers)

Func _GetLoggedOnUsers()
    Local $sSubkey, $i = 0, $aUserInfo, $aResult[1][2], $iCount
    While 1
        $i += 1
        $sSubkey = RegEnumKey("HKEY_USERS", $i)
        If @error Then ExitLoop

        If StringRegExp($sSubkey, "^S-1-5-21-(\d+-){3}\d+$") Then
            $iCount += 1
            $aUserInfo = _Security__LookupAccountSid ($sSubkey )

            Redim $aResult[$iCount + 1][2]
            $aResult[$iCount][0] = $aUserInfo[1] & "\" & $aUserInfo[0]
            $aResult[$iCount][1] = $sSubkey
        EndIf
    WEnd
    $aResult[0][0] = $iCount
    Return $aResult
EndFunc

Thank you so much genius257! This works like a charm but it take a considerably longer time to generate the SID. Not sure why but it works :)

Oh this is a much quicker way to obtain the SID. Thanks so much jguinch!

Happy to help :)

Yeah, i imagine a better, faster way exists, but i don't know enough about it to be able to help, I'm afraid :)

      Hi Virtual People, 
      I'm trying to lock my screen in Windows 10 but to no avail. 
      Has Windows 10 forbidden this feature? 
      Send("#l") Above code does not work. Even sending Ctrl Alt Del does not work nor as an Admin. 
      Note: I want to lock my screen, not log off. Thanks for been kind.

      Hi Guys,
       
      I`m trying to record with my webcam in 5s intervalls and do some stuff between starting to record and stoping.
      I took code from here: https://www.autoitscript.com/forum/topic/27925-webcam-example/
      and took what looked relevant to me.
      I use 3 different files:
       Is called WMS.au3 and contains all the constants for the dll calls is called rec.au3 and does all necessary dll calls to start a webcam recording to a file Is called stopcam.exe and does the dll calls to stop recording into a file WMS.au3  :

      Unfortunately this is not working as I thought it would be working.
      Does someone see what I´m doing wrong?
      It should record the webcam for about 10 seconds ( a little less) and save that to an .avi file.
      It does not stop the recording , I have to stop the process manually...
      Secondly, which confuses me more is that it creates the test.avi not in the location is specified in the script... its stored in the ScriptDir for whatever reason haha
      I hope you can help me

      Hi everyone, I created a function to gather bitlocker information. It can tell you whether or not a drive is protected, which encryption method is being used, ...
      I tried to cover all the details in the function description
       
      The function (and 3 "internal" functions) :
      ; #FUNCTION# ==================================================================================================================== ; Name...........: _BitlockerDriveInfo ; Description ...: Get Bitlocker information for one or multiple drives ; Syntax.........: _BitlockerDriveInfo([$sDrive[, $sComputer = @ComputerName[, $bDebug = False]]]) ; Parameters ....: $sDrive - Optional: The drive. Allowed values are: ; |"" - Get the info for all available drives ; |Letter: - Get the info for the specific drive ; $sComputer - Optional: The computer from which the info should be requested ; $bDebug - Optional: Shows the hex ReturnValue from the WMI methods if set to True ; Return values .: Success - Returns a 2D array with the following information ; |[string] Drive Letter ; |[string] Drive Label ; |[string] Volume Type ; |[bool] Initialized For Protection ; |[string] Protection Status ; |[string] Lock Status ; |[bool] Auto Unlock Enabled ; |[bool] Auto Unlock Key Stored ; |[string] Conversion Status ; |[string] Encryption Method ; |[int] Encryption Percentage ; |[string] Wiping Status ; |[int] Wiping Percentage ; |[array] Key Protectors (Or [string] "None" if the drive isn't protected) ; Failure - 0, sets @error to: ; |1 - There was an issue retrieving the COM object. @extended returns error code from ObjGet ; |2 - The specified drive in $Drive doesn't exist ; |3 - There was an issue running the WMI query ; Author ........: colombeen ; Modified.......: ; Remarks .......: Requires to be run with admin elevation.

      Hi guys,
      I'm trying to get some information using WMI, from the Win32_EncryptableVolume class.
      I exec my query, filter out the C-drive, but when I need more info using the objects methods, I only get 1 value back and I can't seem to retrieve the other out params that should be there.
      A very minimal version of what I'm trying to do (no error checking etc, very basic). You need to start SciTE as admin or you won't see any results in the console!
      #RequireAdmin $strComputer = @ComputerName $objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $strComputer & "\root\CIMV2\Security\MicrosoftVolumeEncryption") $objWMIQuery = $objWMIService.ExecQuery("SELECT * FROM Win32_EncryptableVolume WHERE DriveLetter='C:'", "WQL", 0) For $objDrive In $objWMIQuery ConsoleWrite("> " & $objDrive.GetConversionStatus() & @CRLF) ConsoleWrite("> " & $objDrive.GetConversionStatus().ConversionStatus & @CRLF) ConsoleWrite("> " & $objDrive.GetConversionStatus().EncryptionPercentage & @CRLF) Next The result from the console is : 
      > 0 > > What I'm expecting to get back is : 
      > 0 > 0 > 0 When using powershell I get this (run as admin is required!!!) : 
      PS C:\WINDOWS\system32> (Get-WmiObject -namespace "Root\cimv2\security\MicrosoftVolumeEncryption" -ClassName "Win32_Encryptablevolume" -Filter "DriveLetter='C:'").GetConversionStatus() ... ConversionStatus : 0 EncryptionFlags : 0 EncryptionPercentage : 0 ReturnValue : 0 ... All I seem to be getting is the ReturnValue when I use the method.
      I've tried this on multiple methods, always ending up with the same result
      Anyone here who has experience with this type of thing?

      This script used to work on an older version of AutoIT. Currently I am running AutoIT v3.3.14.5 and it's failing.
      Func PublicIP() ;Post public facing IP address Local $url = 'https://www.google.com/search?client=opera&q=what+is+my+ip&sourceid=opera&ie=UTF-8&oe=UTF-8' Local $getIPaddress = BinaryToString(InetRead($url)) Local $sStart = 'clamp:2">' Local $sEnd = '</div>' Local $ipaddress = _StringBetween($getIPaddress, $sStart, $sEnd For $i In $ipaddress MsgBox(0, 'External IP', "Your public IP address is " & $i) Next EndFunc ;==>PublicIP The console output shows:
      "C:\Users\user\Documents\AutoIT\Scripts\WSI Tools.au3" (197) : ==> Variable must be of type "Object".: For $i In $ipaddress For $i In $ipaddress^ ERROR ->14:12:16 AutoIt3.exe ended.rc:1 +>14:12:16 AutoIt3Wrapper Finished. >Exit code: 1 Time: 9.811
