How to provide access to type information from an MFC automation server at run time

MORE INFORMATION

Step-by-step example

1. Place the DECLARE_OLETYPELIB macro in the automation object's header file within the class definition.
2. Place the IMPLEMENT_OLETYPELIB macro in the automation object's implementation file at global scope.
3. Override CCmdTarget::GetDispatchIID() in your derived class, and then return the IID of the primary dispatch interface.

   Sample code

   :

         // In the header file for the automation object, say CmyAutoObject.
         virtual BOOL GetDispatchIID(IID* pIID);
   
         // In the implementation file for CmyAutoObject.
         BOOL CMyAutoObject::GetDispatchIID(IID* pIID)
         {
            *pIID = IID_IMyAutoObject;
            return TRUE;
         }
   					

4. Call EnableTypeLib(), in the constructor for the automation object.
