问题描述

怎么到这一步就跑不动了呢？也没有报错？求高手

BOOL Cmain::OnInitDialog()
{
CDialogEx::OnInitDialog();

// TODO:  在此添加额外的初始化

    if (buf[0] == '0')

    /*cout << "客户端发送的数据: " << buf << endl;

    cout << "向客户端发送数据: ";
    cin >> sendBuf;

    send(sClient, sendBuf, strlen(sendBuf), 0);*/
    AfxMessageBox(L"123");
}
return TRUE;  // return TRUE unless you set the focus to a control
// 异常:  OCX 属性页应返回 FALSE

}
这是在一个对话框里添加的socket服务端

解决方案

具体是在这一步"sClient = accept(sServer, (sockaddr FAR*)&addrClient, &addrClientlen);"
