6.3.2 客户端窗口代码片段
（1）“登录”控件代码设计： void CDlgTCPClientDlg::OnBtnLogin() { // TODO: Add your control notification handler code here CString usrName=\
m_edUser.GetWindowText(usrName); if (usrName.IsEmpty()) {
AfxMessageBox(\用户名不能为空！\return;
}
if (!m_ClientSocket.Create()) { AfxMessageBox(_T(\创建失败！\ return;
}
if (!m_ClientSocket.Connect(m_strIP,m_nPort)) { AfxMessageBox(_T(\连接失败！\
m_ClientSocket.Close();

m_edRContent.ReplaceSel(strContent); }
AfxMessageBox(_T(\聊天内容不能为空!\return;
void CDlgTCPClientDlg::IniCtruls() {
