and software developers through the dynamic Connection Library in C language. We now see that Internet software under Wind ows is developed under Winsock. With the launch of Windows 95, Winsock has been formally integrated into Windows systems, and it also includes 16-bit and 32-bit programming interfaces.The implementation of Winsock is generally composed of tw
real-time voice, image transmission, broadcast message and other network transmission.The Winsock interface provides a new method for inter-process communication. It can be used not only for inter-process communication on the same machine, but also for network communication. With the launch of Windows 95. Winsock has been formally integrated into the Windows system, including 16-bit and 32-bit programming
Develop a Winsock application with a large response scale using the completed PortAuthor: Anthony Jones Amol DeshpandeTranslation: Liu xiqi Source: http://msdn.microsoft.com/msdnmag/issues/1000/Winsock/ It is not easy to develop network applications. However, you only need to master several key principles-create and connect a socket and try to connect, then send and receive data. What is really difficult i
the server and client side, to achieve data transfer based on TCP/IP, and finally give the relevant source code. VC in the Winsock API programming development, you need to use the following three files in the project, or there will be a compilation error. 1. WINSOCK. H: This is the header file for the Winsock API and needs to be included in the project. 2. WS
discuss how to use the low-level API function to implement simple Winsock network application design, explain how to operate the socket on the server and client side, realize the data transmission based on TCP/IP, and finally give the relevant source code.

Windows Network Programming 2nd Edition Chapter 2 Winsock Design Notes 1. System architecture. First, see the architecture diagram in Attachment 1. Under ws2_32.dll, it is divided into multiple layers to manage their respective tasks. In WinSock, the so-called provider refers to the packaging of different protocol implementations. For example, TCP has a TCP prov
Since most of the code to explain Winsock is C + +, and Winsock is just some use of Windows APIs, in order to help. NET programmers to understand Winsock2, I have removed the implementation code of the. NET synchronization socket, simplifying it, We have time to debug and see. Attention 1, can only run in Win2000 above the system 2, only to support the TCP protocol, 3. Support IPv4 Changes 1, remove t
broadcast time, there is no guarantee that the receiving end is listening. Datagram socket transmission efficiency is high. 3. Original socket (Raw-protocol interface) Defined: #define SOCK_RAW 3 The original socket holds the full IP header in the packet, and the previous two sockets receive only user data. Therefore, the data can be analyzed by the original socket. The other two kinds of sockets are not commonly used, here is not introduced. The files required for socket development (take
Microsoft Windows Network Programming 2nd Edition translated by Yang Heqing Tsinghua University Press Network Programming for Microsoft Windows 2nd 1. Winsock is a network interface, not a protocol. 2 Winsock has two versions: 1 and 2, which can be distinguished by the function prefix WSA. WSA prefix before the number. However, there are several exceptions: wsastartup, wsacleanup, wsarecvex, Wsagetlasterr

In Windows, network programming is inseparable from Winsock. Therefore, you can directly COPY the class that initializes Winsock and use it. The Code is as follows: # Include The variable types BYTE and WORD are defined as follows: typedef unsigned char BYTE;typedef unsigned short WORD;MAKEWORD macros are defined as follows: Word makeword (BYTE bLow, BYTE bHigh); // low BYTE + high BYTE # define MAKEW
at the application layer, its own wininet. DLL implementation does not depend on Winsock. DLL or ws2_32.dll, but exists independently. At least the current version is like this. The most famous example of wininet-based applications is IE. (4) WinHTTP, which also works on the application protocol layer, provides HT
Winsock process description 1. connection-oriented socket programming (TCP) Server: (1) create a socket) (2) bind the socket to a specific IP address and PORT (3) set the socket to the listening mode and prepare to accept the client's request (listen) (4) Prepare the customer request to arrive. When the request arrives, accept the connection request and return a new socket (accept) corresponding to the connection) (5) send/recv) (6) Return and wait fo
How to Use the WINSOCK Control in PB Original: Da weichun With the need for resource sharing and real-time communication, many computer applications have already moved into the single-man combat mode and moved into joint operations.Networks play an increasingly important role in the computer world. In WINDOWS applications, the WINSOCK control most commonly used for processing real-time communication is p
not only can be used for communication between processes in the same machine, but also support network communication functions. With the introduction of Windows 95. Winsock has been formally integrated into the Windows system and includes 16-bit and 32-bit programming interfaces. And Winsock's development tools can also be found in Borland c++4.0, Visual c++2.0 these C compilers, It consists primarily of a header file named Winsock.h and a dynamic co
