新手请教：unexpected 'class CSrvSocket ('

新建一MFC基于对话框的程序ChatServer，支持Socket。

插入一个Generic Class，命名为CSrvSocket，以public方式继承于CAsyncSocket。

SrvSocket.h
--------------------------------------------------------------------------------------------
#if !defined(AFX_SRVSOCKET_H__AD84633D_8760_42B6_9D7E_403064FFB0D5__INCLUDED_)
#define AFX_SRVSOCKET_H__AD84633D_8760_42B6_9D7E_403064FFB0D5__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#include "ChatServerDlg.h"

class CSrvSocket : public CAsyncSocket
{
public:
CSrvSocket(CChatServerDlg * pDlg);
virtual ~CSrvSocket();

private:
CChatServerDlg * m_pDlg;
};

#endif
----------------------------------------------------------------------------------------------


ChatServerDlg.h
----------------------------------------------------------------------------------------------
#include "SrvSocket.h"

//添加如下成员变量
private:
CSrvSocket * m_LiSocket;
CSrvSocket * m_ConSocket;
----------------------------------------------------------------------------------------------
