Trying to create a new instance in object.

[Digisoul]

Hello there,

I am working an application which automatically sets the status for CALM-AV in Windows Security Center.

Now my question is why its giving error when i tried to create the new instance ?

$oWMI = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $strComputer & "\root\SecurityCenter:AntiVirusProduct").Spawninstance_

thanks in advance.

Get the object reference before trying to use methods of it:

$oWMI = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & @ComputerName & _
        "\root\SecurityCenter:AntiVirusProduct" )

If IsObj($oWMI) Then
    ConsoleWrite("$oWMI is object: " & ObjName($oWMI) & @LF)
Else
    ConsoleWrite("$oWMI is not an object." & @LF)
EndIf

$oWMI.Spawninstance

$oWMI = ""

If you get errors from calling the method, add a COM error handler to see what's up.

Thanks,

I just use this method and its work well

$oAntiVirusProduct = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\.\root\SecurityCenter:AntiVirusProduct")   
If Not @error Then $nAntiVirusProduct = $oAntiVirusProduct.Spawninstance_

Will you please tell me the reason ?

First you got the object reference, then you called the method. That's how it's supposed to work.

In the OP you tried to call the method directly off ObjGet(). It just doesn't work that way.
