救命啊，就写了个简单的COM 接口类就出现N多个错误
本人初学COM，对c++也不是很了解，只能说接触过，一直用C#开发的
就照着书写了接口类就出现N多个错误，求助大侠啊
#pragma once
class IMyUnknown
{
public:
virtual HRESULT _stdcall QueryInterface(const IID& iid, void * *ppv) = 0;
virtual ULONG _stdcall AddRef() = 0;
virtual ULONG _stdcall Release() =0;
};
错误信息：

当然说白了这个3处错误都是同样的错误，但是本人愚钝就是找不出来
