Various kinds of applications based on work was born, like information releasing, data sharing ... .The LAN technology as an essential part of our daily life are also widely used . People transfer and exchange data through LAN to connect with Inter. So it’s very necessary to develop a software which based on instantmessage in LAN. So I make a new design, and implement it on windows platform. In my implementation the client and the server were separated in one program with multi thread mechanism and had a good GUI. It can satisfier most people’s demands. It was very easy to use and the function is very realizable. At last, it is also easy for expanding. Key words LAN。 Instant Messaging。 Client。 Server。 Multi thread 北京理工大學(xué)珠海學(xué)院 2021 屆畢業(yè)設(shè)計(jì)（論文） 目 錄 1. 引言 ..................................................................................................................................................................................................1 課題背景及意義 .....................................................................................................................................................................1 課題現(xiàn)狀 ...................................................................................................................................................................................1 研究目標(biāo) ...................................................................................................................................................................................2 開發(fā)平臺(tái)與技術(shù)的選擇及介紹 ...........................................................................................................................................2 開發(fā)環(huán)境的介紹 ............................................................................................................................................................2 WINDOWS SOCKETS 網(wǎng)絡(luò)編程接口概述 .....................................................................................................................3 開發(fā)平臺(tái)簡(jiǎn)介 ....................................................................................................................................................3 access 數(shù)據(jù)庫 ...............................................................................................................................................................4 2. 需求分析及可行性研究 ...............................................................................................................................................................5 系統(tǒng)分析概況 ..........................................................................................................................................................................5 系統(tǒng)需求分析 ..........................................................................................................................................................................5 功能要求 .........................................................................................................................................................................6 性能要求 .........................................................................................................................................................................6 系統(tǒng)可行性研究 .....................................................................................................................................................................7 技術(shù) 可行性 .....................................................................................................................................................................7 經(jīng)濟(jì)可行性 .....................................................................................................................................................................7 營(yíng)運(yùn)可行性 .....................................................................................................................................................................7 3. 系統(tǒng)設(shè)計(jì)及編碼實(shí)現(xiàn) ...................................................................................................................................................................8 系統(tǒng)基礎(chǔ)認(rèn)知 ..........................................................................................................................................................................8 ......................................................................................................................................................................8 TCP/IP 協(xié)議 .................................................................................................................................................................13 Sockets ...................................................................................................................
