Declares cf to be the class factory.
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.
