Declares CComClassFactoryAutoThread to be the class factory.
DECLARE_CLASSFACTORY_AUTO_THREAD( )
Remarks
CComCoClass includes the DECLARE_CLASSFACTORY macro, which specifies CComClassFactory as the default class factory. However, by including the DECLARE_CLASSFACTORY_AUTO_THREAD macro in your object's class definition, you override this default.
When you create objects in multiple apartments (in an out-of-proc server), add DECLARE_CLASSFACTORY_AUTO_THREAD to your class.
Example
class ATL_NO_VTABLE CMyAutoClass :
public CComObjectRootEx<CComMultiThreadModel>,
public CComCoClass<CMyAutoClass, &CLSID_MyAutoClass>,
public IMyAutoClass
{
public:
DECLARE_CLASSFACTORY_AUTO_THREAD()
// Remainder of class declaration omitted.
