DECLARE_CLASSFACTORY_SINGLETON
Declares CComClassFactorySingleton to be the class factory.
DECLARE_CLASSFACTORY_SINGLETON(
obj
)
Parameters
- obj
[in] The name of your class object.
Remarks
CComCoClass includes the DECLARE_CLASSFACTORY macro, which specifies CComClassFactory as the default class factory. However, by including the DECLARE_CLASSFACTORY_SINGLETON macro in your object's class definition, you override this default.
Example
class ATL_NO_VTABLE CMySingletonClass :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CMySingletonClass, &CLSID_MySingletonClass>,
public IMySingletonClass
{
public:
DECLARE_CLASSFACTORY_SINGLETON(CMySingletonClass)
// Remainder of class declaration omitted.
