    WMI (winspool) and critical section

    alogrep posted a topic in VCL

    HI. Is accessing WMI thread safe? I mean this: I my Thread repeatedly list the print jobs in the sn spool with this code FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator'); FWMIService := FSWbemLocator.ConnectServer('localhost', 'root\CIMV2', WbemUser, WbemPassword); FWbemObjectSet:= FWMIService.ExecQuery('SELECT * FROM Win32_PrintJob','WQL',wbemFlagForwardOnly); oEnum := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant; etc. ...... Do I need to protect that with a criticalsection Acquire/Release? Thank you
