Type libraries expose the interfaces of an OLE control to other OLE-aware applications. Each OLE control must have a type library if one or more interfaces are to be exposed.
The following macros allow an OLE control to provide access to its own type library:
Type Library Access
| DECLARE_OLETYPELIB | Declares a GetTypeLib member function of an OLE control (must be used in the class declaration). |
| IMPLEMENT_OLETYPELIB | Implements a GetTypeLib member function of an OLE control (must be used in the class implementation). |
