Download sample source and code example of TCPIP Server and Client in C#
This source and code describes a classic TCP/IP server that can receive multiple client connections. Focusing is a unique package collection and assembly process used by both the server and client side that allows the user to create specific commands to pass to the server or other or all clients.
There are some new parts in the TCPIPServerClient project. TCPIPClient now has a listbox that lists other connected TCPIPClient connections. After connecting to the server, the user can select those users from the list of "other clients" and send them a text message directly.
As a Windows application developer, there was a need to communicate and send real-time data to other users who were using the same application at the same time. Maybe you develop a program that allows you to create and edit shared network documents... If someone else is viewing the same document and making changes, you need to make sure that the other user doesn't overwrite the changes you make. At that moment. Therefore, there must be a way to communicate to users so that they know that changes are being made.
This article describes a classic TCP/IP server that can receive multiple client connections and handles all data packets coming from client-side connections. Packets are collected and processed on the server, or they can be sent to other individual clients or to all of them simultaneously.
If you're really creative, you can use the server to simply notify clients about other connected clients and pass enough information to each other so they can talk directly to each other (usually called a meet server). Here is a picture of what I call a "GComm" (group communicator) using this principle. This program is a tool to send RTF files and messages to one or more people in a network. The basic mechanism for receiving and constructing data packets is what this article describes.
