关键代码：

void CMFC_TCP_CSocket_ServerDlg::AcceptConnect()
{CClientSocket* psocket = new CClientSocket();psocket->SetDialog(this);if (m_ServerSock.Accept(*psocket))m_socketlist.AddTail(psocket);else{delete psocket;}
}void CMFC_TCP_CSocket_ServerDlg::ReceiveData(CSocket& socket)
{char bufferdata[BUFFERSIZE];int len = socket.Receive(bufferdata,BUFFERSIZE);if (len != -1){bufferdata[len] = 0;POSITION pos = m_socketlist.GetHeadPosition();while (pos != NULL){CClientSocket* socket = (CClientSocket*)m_socketlist.GetNext(pos);if (socket != NULL)socket->Send(bufferdata,len);}}}void CMFC_TCP_CSocket_ServerDlg::OnBnClickedButtonConfig()
{// TODO: 在此添加控件通知处理程序代码m_ServerSock.SetDialog(this);CString strPort, strIP;m_ServerPort.GetWindowText(strPort);m_ServerIP.GetWindowText(strIP);if (!strPort.IsEmpty() && !strIP.IsEmpty()){UINT port = atoi(strPort);m_ServerSock.Create(port,SOCK_STREAM,strIP);BOOL ret = m_ServerSock.Listen();if (ret)MessageBox("设置成功","提示");GetDlgItem(IDC_BUTTON_Config)->EnableWindow(false);}}
