DOC: ADsBuildEnumerator Cannot Be Used with ADSI Collections

SUMMARY

The ADSI specification suggests that ADsBuildEnumerator can be used with any of the ADSI enumeratable objects (objects that expose IADsContainer, IADsCollection, or IADsMembers). ADsBuildEnumerator works only with objects that expose an IADsContainer or IADsMembers interface. ADsBuildEnumerator cannot be used with collection objects (objects that expose IADsCollection). The IADsPrintQueueOperations::PrintJobs, IADsFileServiceOperations::Sessions, and IADsFileServiceOperations::Resources methods all return collections.

IADsCollection * pADsCollection;
   IEnumVARIANT * pEnumVariant;
   {
      IUnknown * pUnk = NULL;
      hr = pADsCollection->get__NewEnum( &pUnk) ;
      if (pUnk){
         hr = pUnk->QueryInterface(IID_IEnumVARIANT,
                                   (void **) &pEnumVariant);
         pUnk->Release();
      }
   }
