wmi object reading is returning null

Recommended Posts

Hi folks,

I am working with win32_printerconfiguration for checking the duplex option is installed or not in the printers.

 

$objWMIService = ObjGet("winmgmts:\\" & @ComputerName & "\root\CIMV2")
            $Error_WMI = @error
            If IsObj($objWMIService) Then
               $colItemsa = $objWMIService.ExecQuery ("Select * from Win32_PrinterConfiguration ", "WQL",$wbemFlagReturnImmediately + $wbemFlagForwardOnly)
               If IsObj($colItemsa) Then
                  For $objPrinters In $colItemsa

                    msgbox(0,"check","entering loop")
                     $NameP = $objPrinters.Name
                     If $NameP = $cfgLocPrinterName[$p - 1] Then
                        $DuplexValue = $objPrinters.Duplex
                     EndIf
                  Next
               EndIf
            Else
               LogCreation("DuplexInstalledCheck", "WMI object", "Error in reading WMI object")
            EndIf

 

script is existing from the for loop. it is not even printing the msg box titled check. any one please help

You used the wrong section for you problem. ;)

This code works for me on Win8.1

$objWMIService = ObjGet("winmgmts:\\" & @ComputerName & "\root\CIMV2")
$Error_WMI = @error
If IsObj($objWMIService) Then
   $colItemsa = $objWMIService.ExecQuery ("Select * from Win32_PrinterConfiguration ", "WQL", 0x30)
   If IsObj($colItemsa) Then
      For $objPrinters In $colItemsa
        $NameP = $objPrinters.Name
        $DuplexValue = $objPrinters.Duplex
        msgbox(0,"check","entering loop" & @CRLF & $NameP & @CRLF & $DuplexValue)
      Next
   EndIf
Else
   ConsoleWrite("Error" & @CRLF)
EndIf

Else
   ConsoleWrite("Error" & @CRLF)
EndIf

 

​Even for me it is working in some systems. But in the system that i need this, no luck. :(

i tried to get the error by adding objevent autoit.error. 

i got error number as 80041006. i've googled it and got invalid class reference could be the reason. so i tried to print the variable $colItemsa. it is not giving anything. Then i convert that variable to string from array. No out put.

      Hello,
      I am trying to make a program that will uninstall some software, provided by some form of a list. I have this

If I run script with admin rights then the software gets uninstalled.
      At the following link there is a script by JLogan3o13 but it does not either uninstall software, unless run as admin..
      Is there some way to uninstall software using wim or wimc by providing user name and password?

      Hi all,
      I have a bit of code that works on my old Win10 PC, that fails on my new Win10 PC, and I think the only significant difference is the version of Autoit - old PC has 3.3.12, new has 3.3.14.
      I couldn't find anything mentioned in the change logs though, so perhaps I'm wrong.
      Anyway, the code to replicate my issue is:
      Test('username', 'DOMAIN') ; THIS ERRORS: ;Test('localun', 'DOMAIN') ; THIS ERRORS: ;Test(' ', ' ') ; THIS ERRORS: ;Test('', '') ; THIS ERRORS: ;Test('localun', '') ; THIS ERRORS: ;Test('', 'DOMAIN') Func Test($un, $dom) $compName = 'PCNAME' $FullName = '.' $Description = '.' ; get the WIM object $objWMIService = ObjGet("winmgmts:\\" & $compName & "\root\cimv2") ; get default user full name and description $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") If IsObj($objAccount) Then $FullName = $objAccount.FullName $Description = $objAccount.Description EndIf ConsoleWrite($FullName & @CRLF) ConsoleWrite($Description & @CRLF) Return EndFunc  
      On my old PC this code will output just . and . for each of those line currently commented out. Which is fine.
      On my new PC any of those commented out lines of code cause an error, and the script won't even compile.
      $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") $objAccount = $objWMIService^ ERROR I'm very much a newb with the WMI stuff and objects, but it looks like the .Get property is failing when either $un or $dom aren't valid in v3.3.14, whereas in 3.3.12 the .Get would fail to return an object, which is then caught by the If statement.
      Am I on track with this? Is there some new/better way to code the example so that 3.3.14 will compile it?

      Edit: I found out from looking into the post from coffeeturtle that not all motherboards support WMI temperature reading. You have to explore the WMI namespaces for your system!
      I (stupidly) fried a computer. It was an old Zotac small form factor device that was junked at work, so I turned it into a home theater PC.
      But I had put it in my "audio rack", which has glass doors and not very good ventilation. Normally I would open the doors while it was running and I use a media remote which would hibernate the system. At some point, it woke up by itself (probably Windows Update) and did not go to sleep again. Unfortunately this happened during the summer months while I was away on a small holiday and of course the glass doors were closed.
      When I finally noticed the system was on, it was super hot and the fan was at full blast. Dead. No POST, no green light on the mainboard even with a new power supply, old mechanical laptop hard drive gives errors when connected to another device. My next home project will be to make some appropriate ventilation in the audio cabinet.
      For the replacement I bought a used HP ultra small form factor machine and decided to start working on an app to monitor the ambient temperature sensor on the motherboard and shutdown the system if needed. I used some code for smooth label updates from here (needed updating to work with latest AutoIT) and temperature conversion from here (not really needed, only if you want temperatures in something other than C).
      Maybe I will work on this some more and make it configurable with an .INI file or even storing the settings in registry, but since I probably won't I thought I'd put it up as an example of what a non-expert can do with an afternoon of coding and ideas from the community here.
      This uses an ambient temperature sensor populated on HP machines in HP-specific WMI extensions but the WMI query can easily be changed to any available sensor including CPU or GPU.
      The watchdog monitors temperature, warns with S.O.S beeping if the set point is exceeded, and either shuts down if a timeout is reached while the temperatures are high or goes back to monitoring if the temperature goes lower then the set point, and logs events to the Windows application event logs.
      The GUI it puts up is very small at the top center of the screen (very small on a 4k display anyway).
      #requireadmin because of the WMI query.
      A timer for the WMI query because of prior experience using similar functions in WinPE to get model infos from HP WMI bios extensions.
      If you play around with this, please post your fixes/improvements/changes back to this thread.
      Have fun!
      Edit: Updated to show "Unable to query temperature" if the WMI query returns a null

      Hello,
      In Windows 10 PowerShell, one can do this to change the metric for a NIC in Windows 10:
      Get-NetAdapter | Where-Object -FilterScript {$_.InterfaceAlias -Eq "Ethernet 2"} | Set-NetIPInterface -InterfaceMetric 2 I know I can script the above PowerShell line (and it works!), but I wanted to try something I hadn't done before after looking into jguinch's most excellent Network configuration UDF. I wanted to make use of the SetIPConnectionMetric method in the WMI classes. There is an example VBscript here but this is not for Windows 10. Using AutoIT would also give better control over capturing error return codes than with PowerShell.
      But I cannot get my script to work! The return from SetIPConnectionMetric() is 0, which would indicate success. Yet the change does not happen. I also tried WMI methods using .put_ but this fails.
      Anyone more experienced than I have ideas to make this work?
      #RequireAdmin _SetNicInterfaceMetric2("Ethernet 2", "2") Func _SetNicInterfaceMetric2($NIC_NAME, $METRIC) Local $s_setIndx = 0 $objWMIService = ObjGet("winmgmts:{impersonationLevel = impersonate}!\\" & "." & "\root\cimv2") $colNICItems = $objWMIService.ExecQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionID = '" & $NIC_NAME & "'", "WQL") If IsObj($colNICItems) Then For $objItem In $colNICItems $s_nicIndex = $objItem.Index Next ConsoleWrite("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE Index = '" & $s_nicIndex & "'" & @CRLF) $colNAC = $objWMIService.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE Index = '" & $s_nicIndex & "'", "WQL") If IsObj($colNAC) Then For $objNetCard In $colNAC If $METRIC <> $objNetCard.IPConnectionMetric Then ConsoleWrite("Metric was set to " & $objNetCard.IPConnectionMetric & ".
