50分，线程毒死了

C/C++ code

服务器三个线程，1. 第一个线程 分配时接受客户端的数据2. 第二个线程扫描一个map并主动推送用户在线列表的线程，3.第三个线程 检测下线的用户，一旦检测到，则通知服务器界面，让服务器界面去掉该用户，并告知其他用户。客户端检测了 ，没有问题， 我单独写了服务器，可以接收客户端的数据和客户端发送的心跳包。都收到了。但是开启客户端，对服务端调试，则发现很多地方进步了。很是奇怪。大家能帮忙看看 这个三个线程是否存在问题嘛?谢谢了//处理客户端的数据unsigned int CMyServerDlg::ReceiveUserPacke(void*){    while(1)    {        if(WaitForSingleObject(pThis->hKillReceiveEvent,0)==WAIT_OBJECT_0)            return 0;

[解决办法]
MFC的？
给你看几段我服务端的代码。
我用双向链表存在线列表。

C/C++ code

void CClientSocket::OnReceive(int nErrorCode){    g_cs.Lock();    pWnd = static_cast<CCUPJOINServerDlg*>(AfxGetMainWnd());    Message msg;    Receive(&msg, sizeof(msg));  //得到数据    if (msg.iType == VS_KEEPONLINE)     return; //心跳包，不处理。        if (msg.iSubType == VS_LOGIN)    {        int RecvLogin = pWnd->UserCheck(msg.strName, msg.strPassword);        if (RecvLogin == 1) // normal user            msg.iType = VS_USER;        else if (RecvLogin == 2) // admin user            msg.iType = VS_ADMIN;        else        {            LinkedUser.Delete(LinkedUser.Find(msg.strName));            msg.iType = VS_FAIL;            msg.iSubType = VS_LOGIN;            Send(&msg, sizeof(msg));            return;        }        //CString UserName = msg.strName;        CString strtmp; UINT t;        GetPeerName(strtmp, t);        msg.SetContent(strtmp);        if (CheckBaned(strtmp, msg))        {            msg.iType = VS_FAIL;            msg.iSubType = VS_BANED;            Send(&msg, sizeof(msg));            return;        }        int IsExist = pWnd->CheckRepeatAndKick(msg);        this->SetUserName(msg.strName);        pWnd->m_pClientSocketList.AddTail(this);        //CUP状态        if (pWnd->m_CupApply)            msg.n_UserNum = 1;        else if (pWnd->m_CupStart)            msg.n_UserNum = 2;        else            msg.n_UserNum = 0;        if (IsExist)            pWnd->SendMsg(msg); //给全局发上线消息        else        {            pWnd->SendMsg(msg); //给全局发上线消息            LinkedUser.Append(0, msg.strName);//写在这里添加后，链表里存的UserName不会重复。        }        MakeOnlineList();//发送在线列表        return;    }...}
