Test for WMI Entries

[Darktan]

I'm coding some hardware and software inventory software. One of the issues I'm running up against is finding the number of processors on a server. The problem is the WMI entry I'm looking for doesn't always exist and if it doesn't, it bombs out the script. (\root\CIMV2 and looking for $objItem.NumberOfLogicalProcessors and $objItem.NumberOfProcessors) Windows 2003 server did not have that WMI entry when it first came out. It has since been added via KB932370. Now I could search for that KB to be installed or check the service pack level, but an easier way in my mind is to just look for the WMI entry. Problem is I don't know how to code it. I'm just getting into WMI. Can this be done? Once I get some data back, I hopefully will be patching everything to be the same and this won't be an issue.

you should use a COM-Errorhandler:

$objComError = ObjEvent ( "AutoIt.Error", "_COMError" )
Func _COMError()
    SetError($objComError.number)
EndFunc

AHA! Exactly what I needed. Thank you.

Still new to WMI and COM stuff. So all this new learning will make my scripts that much better or that much more complex and shaky. I can't wait to find out which way it goes.

Thanks again.

Peace
