Here that the new view - really means, GetTypeInfo is caused on IDispatch which, seemingly, at ServerXMLHTTP is not present - is only IUnknow and IStream. Then a new question: and how it is correct such situation? It is clear that before call GetTypeInfo it is necessary to pull QueryInterface for obtaining IDispatch. If IDispatch received, we work, and if is not present? VBA, for example, for ResponseStream in the column "Type" produces "Variant / <Unsupported object type>". To be restricted to the similar approach?
