The automation type description interfaces provide a way to read and bind to the descriptions of objects in a type library. These descriptions are used by ActiveX clients when they browse, create, and manipulate ActiveX (Automation) objects.
A type library is accessed through the ITypeLib interface. The ITypeLib interface provides access to information about the type description in a type library. The descriptions of individual objects are accessed through the ITypeInfo interface.
