To develop network server programs in Windows, it is undoubtedly the most efficient to Use WinSock to complete the port model. The Winsock completion port model is implemented using the overlapping Io and Completion Ports of Widnows. After completing the port model, it is relatively simple, but to master the Winsock completion port model, you need to have a certa

process enters the "transaction" status. In this status, the customer initiates a service request. When the customer issues a quit command, the process enters the "Update" status. In this status, the mail server releases the resources obtained in the "operation" status, sends a message, and terminates the connection.As an offline Model Protocol, the mail server must have an automatic disconnection timer, which can be at least 10 minutes. After the time limit is exceeded, the mail server will no

type. For example, if the connection rate is high (because the connection duration is short or the traffic peak occurs ), the acceptex that needs to be waited for is certainly more than the client connection that occasionally enters. It is wise to use an application to analyze traffic conditions and adjust the number of acceptex waits, rather than fixed to a certain number. For Windows2000, Winsock provides some mechanisms to help you determine whet

The Winsock control can connect to a remote machine through UDP (User Datagram Protocol) or TCP (Data Transmission Protocol) and exchange data. Both protocols can be used to create client and server applications. Like the timer control, the Winsock control does not have a visual interface when running.Possible UseCreate a client application that collects user information before reaching the central server.C

Use the socket function to create a socket. The socket type is defined in Winsock. h: Socket socket (int af, int type, int Protocol ); AF is the Protocol address family. Here we use IPv4, which must be af_inet Type is socket type. If TCP/IP is used, type is set to sock_stream. If UDP is used, sock_dgram is used. Protocol is used to limit specific transmission when multiple entries are provided for the given address family and socket type. For TC

Socket architecture for Windows NT and Windows 2000 Develop Winsock applications with large response ScaleProgramIt is helpful to have a basic understanding of the socket architecture of Windows NT and Windows 2000. Unlike other types of operating systems, the transfer protocols for Windows NT and Windows 2000 do not have an interface that is similar to sockets and can communicate directly with applications, instead, it uses a more underlying API

I don't know whether this program has any value. I learned WinSock programming first. Before the official start, introduce the client/server programs. Many network programs use the client/server model (C/S model. In fact, we are very familiar with this architecture. The relationship between browsers and web servers is the relationship between C/S. Data Interaction between well-known servers and clients is performed according to certain standards. The

Winsock BASIC Programming Socket " bore " " socket " BSD UNIX process communication IP address generally executes multiple service software, providing several services at the same time. Each service opens a socket and binds to a port, with different ports corresponding to different services. The socket is like a porous socket, as its English intended. A host vac, some provide 110 volts AC, some provide cable TV programs. The custome

Summary With the rapid development of the Internet, the communication of the network interface enables us to receive all the information that happens all over the place immediately. When we use various browser to browse various outlets, as long as the server can provide chat (chat) service items, we can through browser provided chat program and other users on the network to talk about the exchange of experience. This article designs a chat application with the

The example shows the method of Winsock file transfer in Windows network programming, and it has some reference value for Winsock network programming under Windows. The program code is mainly based on the TCP stream protocol Winsock network File Transfer example, using Windows C language written. You can implement file transfer functions that pass any format fil

. Reference the good description on the Internet: "blocking block means that you call someone's phone number, but this person is not there, so you can wait for him to return, and no longer use the phone number. Synchronization is about the same as blocking. Non-blocking nonblock means that you call someone, but this person is not there, so you can stop the call and call again later. As for the time when he came back, he only had to make a call. This is called "Round Robin/poll ". Asynchronous me

The previous notes documented Winsock's introductory programming and the fun of Winsock programming. But this is not to grasp the Winsock, deepen the understanding of theoretical knowledge will make subsequent learning more handy. Therefore, this note will record some of the basic theory of Winsock knowledge, because it is a note, in view of the limited speed of

Winsock is a protocol-independent interface. Here we mainly introduce the widely used IP protocol, whose version is the current IPv4 protocol (not introduced for the time being ). IPv4 addressing In IPv4, the address of a computer is expressed in a 32-bit binary format, which is called an IP address. when a client uses TCP or UDP to communicate with the server, its IP address and communication port must be specified. when the server wants to lis
