How to get data IWbemClassObject **

Hello How to get data from this array? Or how to get all the names that I can extract?

hres = pSvc->ExecNotificationQueryAsync( _bstr_t("WQL"), _bstr_t("SELECT * " 
            "FROM __InstanceCreationEvent WITHIN 1 WHERE TargetInstance ISA 'Win32_Process'"), 
        WBEM_FLAG_SEND_STATUS,  NULL, pStubSink);
for (int i = 0; i < lObjectCount; i++)
{
    VARIANT varName;
    hres = apObjArray[i]->Get(_bstr_t(L"__CLASS"),
        0, &varName, 0, 0);

    if (FAILED(hres))
    {
        cout << "Failed to get the data from the query"
            << " Error code = 0x"
            << hex << hres << endl;
        return WBEM_E_FAILED;       // Program has failed.
    }

    printf("Name: %ls\n", V_BSTR(&varName));
}

Your code is not working because the results of the ExecNotificationQueryAsync method must be processed using a IWbemObjectSink object. Try this MSDN sample Receiving Event Notifications Through WMI Also you can use a tool like the WMI Delphi Code Creator to generate C++ Code to access the WMI.
