visual studio MFC connect失败问题

Question

请各位帮忙看一下问题。
在写一个程序，需要在后台进行socket连接，可是发现除了在button进程中connect连接成功，在Ontimer或单独thread都失败。
ontimer和AfxBeginThread的实现：

void CTimerDlg::OnTimer(UINT_PTR nIDEvent)
{
    // TODO: Add your message handler code here and/or call default
    switch (nIDEvent)
    {
    case 1:
        int ck = 1;
        int result_id;
        int i = 1;
        m_socket[i] = WSASocket(AF_INET, SOCK_STREAM, IPPROTO_TCP, NULL, 0, 0);
        if (INVALID_SOCKET == m_socket[i]) {
            ck = 0;
            MessageBox("创建套接字失败！");
            return;
        }

        if (SOCKET_ERROR == WSAAsyncSelect(m_socket[i], m_hWnd, UM_SOCK1, FD_READ))
        {
            ck = 0;
            MessageBox("注册网络读取事件失败!");
            //return FALSE;
        }

        SOCKADDR_IN addrSrv;
        addrSrv.sin_family = AF_INET;
        addrSrv.sin_port = htons(tcp_local_port);
        addrSrv.sin_addr = tcp_local_ip;
        tcp_local_port += 1;

        bind(m_socket[i], (SOCKADDR*)&addrSrv, sizeof(SOCKADDR));

        // SOCKADDR_IN addrSrv;
        CString remote_ip_str;
        CString remote_port_str;

        if (remote_ip_str.IsEmpty()) {
            addrSrv.sin_addr.S_un.S_addr = inet_addr(ROMOTE_IP_ADDRESS);
        }
        else {
            addrSrv.sin_addr.S_un.S_addr = inet_addr(remote_ip_str);
        }

        if (result_id < 0)

通过断点检查socket等参数都没有发现问题，可就是在connect时返回-1
