[Solved] Problem with ObjGet()

[UEZ]

I got a system where I get the em:

Line -1:

Error: The requested action with this object has failed.

although IsObj() is true!

Here a snippet:

$HKLM = 0x80000002
    $BaseKey = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\"
    $objReg = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $srv & "\root\default:StdRegProv")
    If IsObj($objReg) Then
        $objReg.GetStringValue($HKLM, $BaseKey, "Test", $OS_Test)
    EndIf

When I use Scriptomatic against the system no information will be sent back (each value is empty)!

I want to avoid that my script is terminating with an em and I don't want use RegRead()!

Has somebody an idea for a workaround?

Thanks,

UEZ

You need something like this:

Global $oError = ObjEvent("AutoIt.Error", "_ErrFunc")

$HKLM = 0x80000002
$srv = "localhost"
$BaseKey = ""
$OS_Test = ""
$BaseKey = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\"
$objReg = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $srv & "\root\default:StdRegProv")
If IsObj($objReg) Then
    $objReg.GetStringValueq($HKLM, $BaseKey, "Test", $OS_Test)
EndIf



Func _ErrFunc()
    Return
EndFunc

Thanks a lot trancexx! Working as expected! We simple solution.

@UEZ: Just to clarify; did you notice it had nothing to do with IsObj()? You had an object, and it failed to do something, which lead to "Error: The requested action with this object has failed.". What trancexx gave you was error handling to silently deal with the error.

If for some reason you tried $objReg.GetStringValueq() when $objReg is not an object, the message would have been 'Variable must be of type "Object".'

PsaltyDS,

the issue is that I use the code from my 1st post (only a snippet) to read a value from the registry of a remote system. I don't know the reason why communication is not working properly. When I use Scriptomatic it gives me nothing back! I assume that the WMI service is not working properly on the remote system or the system it too busy (restart of the service or better restart of the system will probably solve the problem).

My goal is that such kind of circumstances will not terminate the script and trancexx' idea (I don't know why I didn't catch that because it is not unknown to me) is what I searched for.

Thanks for your comment.
