IProvideClassInfo3

IProvideClassInfo3

This interface is an extension to IProvideClassInfo2 to provide various pieces of object-level information directly from the object (as opposed to using the registry or some other means that does not involve the object). As such it is intended to be a generic object-information interface. This interface also corrects the absence of an LCID in IProvideClassInfo::GetClassInfo.
