Visual C++ Network Programming Tutorial PDF267

Visual C++ is a versatile and powerful programming language that can be used to create a wide variety of applications, including network programs.

Network programming involves writing code that allows computers to communicate with each other over a network. This can be done using a variety of protocols, such as TCP/IP, UDP, and HTTP.

Visual C++ provides a number of libraries that can be used to simplify network programming. These libraries include:
The Windows Sockets (Winsock) library, which provides a set of functions that can be used to create sockets, send and receive data, and manage network connections.
The Microsoft Foundation Classes (MFC), which provide a set of classes that can be used to create graphical user interfaces (GUIs) for network applications.
The ATL Server Framework, which provides a set of classes that can be used to create COM-based network servers.

In this tutorial, we will show you how to use Visual C++ to create a simple network program that sends and receives data over a TCP/IP connection.

Creating a New Visual C++ Project

To create a new Visual C++ project, open Visual Studio and select the "File" menu. Then, select "New" and then "Project".

In the "New Project" dialog box, select the "Visual C++" project type and then select the "Win32 Console Application" template.

Enter a name for your project and then click the "OK" button.

Adding the Winsock Library

To add the Winsock library to your project, right-click on the project in the Solution Explorer window and select "Properties".

In the "Project Properties" dialog box, select the "Linker" tab and then click the "Input" button.

In the "Additional Dependencies" field, add the following library:

Click the "OK" button to save your changes.

Creating a Socket

The first step in creating a network program is to create a socket. A socket is a communication endpoint that is used to send and receive data.
