				else
				{
				msg->Senalize(*m_aS essionOut);
				m_aSessionOut->Flush0;
				retum TRUE;
				／／对方关闭了连接
				m_bClose=true;
				CloseSocket0;
				m_dlg->CloseSessionSocket0;
				return FALSE;
				7)添加CChatClient类关闭连接函数CloseSocket0。
				       void CChatClient::CloseSocket()
				         {
				if(m_aSessionln)
				                   {
				                     delete m_aSessionln;
				m_aSessionIn=NULL;
				                   }
				if(m_aSessionOut)
				                   {
				                     delete m_aSessionOut;
				m_aSessionOut=NULL;
				if(m_sfSocketFile)
				                   {      .
				                       delete m_aSessionOut;
				m_sfSocketFile=NULL;
				                 }
				 Close();
				m_blnit=false;
				m_bClose=true;
				          }
				8)添加 CChatClient类获取主机名函数 GetLocalHostName O。
				int CChatClient::GetLocaIHostName(CString &sHostName)
				{
				        char szHostNamel256J;
				        int nRetCode;
				                              nRetCode=gethostname(szHostN ame,sizeof(szHostName》;
				               if(nRetCode !:=:0)
				          {
