Type Library Access
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
| Name | Description |
|---|---|
| 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). |
DECLARE_OLETYPELIB
Declares the GetTypeLib member function of your control class.
DECLARE_OLETYPELIB(class_name)
Parameters
class_name
The name of the control class related to the type library.
Remarks
Use this macro in the control class header file.
Requirements
Header: afxdisp.h
IMPLEMENT_OLETYPELIB
Implements the control's GetTypeLib member function.
IMPLEMENT_OLETYPELIB(class_name, tlid, wVerMajor, wVerMinor)
Parameters
class_name
The name of the control class related to the type library.
tlid
The ID number of the type library.
wVerMajor
The type library major version number.
wVerMinor
The type library minor version number.
Remarks
This macro must appear in the implementation file for any control class that uses the DECLARE_OLETYPELIB macro.
