如果客户端向服务器发送消息，则相同的消息服务器发送给每个连接的客户端，除了发送消息的消息

问题描述

void CSocketClientDlg::OnBnClickedSendmsg()
{
	// TODO: Add your control notification handler code here
	UpdateData(TRUE);
	if(m_sSendMsg.GetLength() == 0)
	{
	    MessageBox("Type your Message !");
		return;
	}
	CString sStr = ":";

	CString sUserName = m_sUserNmae +sStr+ m_sSendMsg;
	m_pClientSocketSever->Send(sUserName,sUserName.GetLength());
	m_SentList.InsertItem(0,sUserName);

	CString sTime = CTime::GetCurrentTime().Format("%H:%M:%S");
	m_SentList.SetItemText(0,1,sTime);

	m_nCounter = m_SentList.GetItemCount();
	m_DeleteItems = m_nCounter;
	m_nCounter++;
	m_sSendMsg =" ";
	UpdateData(FALSE);

//服务器

//Server

void CServerSocketDlg::Reciever(char chData[100])
{
	m_list.InsertItem(0, chData);
	CString sTime = CTime::GetCurrentTime().Format("%H:%M:%S");

	m_list.SetItemText(0,1,sTime);
	m_nCounter = m_list.GetItemCount();

	m_nNumOfMsg = m_nCounter;
	m_sSendMsg = chData;
	m_nCounter++;
	UpdateData(FALSE);
}

void CServerSocketDlg::OnBnClickedSendmsg()
{
	UpdateData(1);
	if(m_sSendMsg.GetLength() == 0)
	{
	    MessageBox("Type your Message !");
		return;
	}

	CString sStr = "  :";
	CString sUserName = m_sUserName +sStr+ m_sSendMsg;
	m_pServer->SendMessage(sUserName);

	m_SentList.InsertItem(0, sUserName);
	CString sTime = CTime::GetCurrentTime().Format("%H:%M:%S");

	m_SentList.SetItemText(0,1,sTime);
	m_nCounter = m_SentList.GetItemCount();

	m_nSentMsgNum = m_nCounter;
	m_nCounter++;
	m_sSendMsg = " ";

	UpdateData(0);


}
