高效服务器编程模型，达到理论100W并发服务(Efficient Server Programming Model)

基于Winsock的网络编程小程序，可以实现FTP的上传和下载。(Winsock-based network programming applets, can be achieved FTP upload and download.)

说明：  TCP服务器和客户端C++类，提供简单的TCP通讯功能(TCP server and client c + + class, provide simple TCP communication function)

生日快乐歌，基于stc89c52单片机，利用定时器模拟pwm(Music based on 51 Singlechip)

private void Connect_Click(object sender, System.EventArgs e)        {            //将光标置为等待状态            Cursor cr = Cursor.Current;            Cursor.Current = Cursors.WaitCursor;            String a ,b,c;              //用110端口新建POP3服务器连接            Server = new TcpClient(PopServer.Text, 110);            Status.Items.Clear();             try            {                //初始化                NetStrm = Server.GetStream();                RdStrm = new StreamReader(Server.GetStream());                Status.Items.Add(RdStrm.ReadLine());                 //登录服务器过程                Data = "USER " Username.Text CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                Status.Items.Add(RdStrm.ReadLine());                 Data = "PASS " Password.Text CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                Status.Items.Add(RdStrm.ReadLine());                 //向服务器发送STAT命令，从而取得邮箱的相关信息：邮件数量和大小                Data = "STAT" CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                //Status.Items.Add(RdStrm.ReadLine());                 //改变按钮的状态                Connect.Enabled = false;                Disconnect.Enabled = true;                Retrieve.Enabled = true;                 //将光标置回原来状态                Cursor.Current = cr;             }            catch (InvalidOperationException err)            {                Status.Items.Add("Error: " err.ToString());            }        }

用socket编程实现点对点通信，TCP客户端程序，TCP服务器程序，以及UDP点对点聊天通信。(Point to point communication, TCP client, TCP server, and UDP peer chat communication socket programming.)

利用Libnids开发包设计的检测攻击的源代码(use Libnids development kits designed detection of the source code attacks)

本程序可以用来监控本地网络，捕获一段时间内以本机为源地址或目的地址的IP数据包（不包括以广播形式发出的数据包），统计IP数据包的信息，列出本机与其他主机之间不同协议类型IP数据包的流量。(This procedure can be used to monitor the local network, capturing a period of time to this machine as the source or destination addresses of IP packets (including broadcast packets sent), statistics of IP packets, lists the machine with The flow of data packets IP between different protocol types in other hosts.)

创建一个新进程范例。这是孙鑫视频中的范例，能帮助初学者了解进程的相关知识，可以看看，虽然比较简单(create a new process in vc++)
