相对于DELPHI来说有些麻烦，只能通过构造函数传参数。TCppInterfacedObject的定义如下：
1 #if !defined(INTFOBJECT_IMPL_IUNKNOWN)
2 #define INTFOBJECT_IMPL_IUNKNOWN(BASE) \
3 ULONG __stdcall AddRef() { return BASE::_AddRef();} \
4 ULONG __stdcall Release(){ return BASE::_Release();} \
5 HRESULT __stdcall QueryInterface(REFIID iid, void** p){ return BASE::QueryInterface(iid, p);}
6 #endif

9 class TCppInterfacedObject: public TInterfacedObject,
10 public INTF1, public INTF2, public INTF3
11 {
12 protected:
13 typedef TCppInterfacedObject<INTF1, INTF2, INTF3> _COM_CLASS;
14 public:
15 INTFOBJECT_IMPL_IUNKNOWN(TInterfacedObject);
16 };
