Abstract:The local area network chats immediately through carries on the text to chat with the pronunciation chats realizes each other communication, the exchange information. This local area network chatted the programming mainly to use Visual immediately the C++ programming environment, has realized in LAN the on-line user's text the pronunciation interactive
Involved in the design to the network correspondence basic principle and the socket programming and the pronunciation processes the API technology. Because the procedure is in TCP Under the IP environment moves, therefore divides the server end and the client side. The server end and the client side are through establishes Socket to link realizes chats the function.
This design mainly emphatically chats in the pronunciation the part, mainly between the flow and various modules relations and the socket processing which chats by the pronunciation primarily explained in this paper.
Keywords: Visual C++ programming environment network communication fundamentals Socket programming API.
