DECLARE_CLASSFACTORY_EX

Article

Declares cf to be the class factory.

Syntax

      DECLARE_CLASSFACTORY_EX( 
   cf  
)

Parameters

cf
[in] The name of the class that implements your class factory object.

Remarks

The cf parameter must derive from CComClassFactory and override the CreateInstance method.

CComCoClass includes the DECLARE_CLASSFACTORY macro, which specifies CComClassFactory as the default class factory. However, by including the DECLARE_CLASSFACTORY_EX macro in your object's class definition, you override this default.

Example

class ATL_NO_VTABLE CMyCustomClass :
   public CComObjectRootEx<CComSingleThreadModel>,
   public CComCoClass<CMyCustomClass, &CLSID_MyCustomClass>,
   public IDispatchImpl<IMyCustomClass, &IID_IMyCustomClass, &LIBID_NVC_ATL_COMLib, /*wMajor =*/ 1, /*wMinor =*/ 0>
{
public:
   DECLARE_CLASSFACTORY_EX(CMyClassFactory)

   // Remainder of class declaration omitted.
