有没有socket高手来救救我，快哭了，小弟在此谢过，

Question

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

// TODO:  在此添加额外的初始化
const int BUF_SIZE = 64;
WSADATA         wsd;            //WSADATA变量  
SOCKET          sServer;        //服务器套接字  
SOCKET          sClient;        //客户端套接字  
SOCKADDR_IN     addrServ;;      //服务器地址  
char            buf[BUF_SIZE];  //接收数据缓冲区  
char            sendBuf[BUF_SIZE];//返回给客户端得数据  
int             retVal;         //返回值  
//初始化套结字动态库  
if (WSAStartup(MAKEWORD(2, 2), &wsd) != 0)
{
    AfxMessageBox(L"WSAStartup failed!");
    return 1;
}

//创建套接字  
sServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (INVALID_SOCKET == sServer)
{
    AfxMessageBox(L"socket failed!");
    WSACleanup();//释放套接字资源;  
    return  -1;
}

//服务器套接字地址   
addrServ.sin_family = AF_INET;
addrServ.sin_port = htons(8088);
addrServ.sin_addr.s_addr = INADDR_ANY;
//绑定套接字  
retVal = bind(sServer, (LPSOCKADDR)&addrServ, sizeof(SOCKADDR_IN));
if (SOCKET_ERROR == retVal)
{
    AfxMessageBox(L"bind failed!");
    closesocket(sServer);   //关闭套接字  
    WSACleanup();           //释放套接字资源;  
    return -1;
}

//开始监听   
retVal = listen(sServer, 1);
if (SOCKET_ERROR == retVal)
{
    AfxMessageBox(L"listen failed!");
    closesocket(sServer);   //关闭套接字  
    WSACleanup();           //释放套接字资源;  
    return -1;
}

//接受客户端请求  
sockaddr_in addrClient;
int addrClientlen = sizeof(addrClient);
sClient = accept(sServer, (sockaddr FAR*)&addrClient, &addrClientlen);
if (INVALID_SOCKET == sClient)
{
    AfxMessageBox(L"accept failed!");
    closesocket(sServer);   //关闭套接字  
    WSACleanup();           //释放套接字资源;  
    return -1;
}

while (true)
{
    //接收客户端数据  
    ZeroMemory(buf, BUF_SIZE);
    retVal = recv(sClient, buf, BUF_SIZE, 0);
    if (SOCKET_ERROR == retVal)
    {
        AfxMessageBox(L"recv failed!");
        closesocket(sServer);   //关闭套接字  
        closesocket(sClient);   //关闭套接字       
        WSACleanup();           //释放套接字资源;  
        return -1;
    }
    if (buf[0] == '0')
        break;
        为什么在    “sClient = accept(sServer, (sockaddr FAR*)&addrClient, &addrClientlen);”就停着不动了啊？怎么改呢？

照你这样说肯定不会动，因为你只开启了服务器，而没有开启客户端，并且你的accept函数可以接受一个连接阻塞，直到对方存在，如果没有连接上等待队列现在，套接字是阻塞显着。那么你的客户端没有连接的话。。。断点肯定是进不去的呀！！！
