簡(jiǎn)述
當(dāng)今世界電子郵件已經(jīng)是網(wǎng)絡(luò)生活中不可或缺的，相信每個(gè)認(rèn)知網(wǎng)絡(luò)的人都會(huì)有一個(gè)或多個(gè)自己的電子郵箱，人們通過(guò)電子郵件進(jìn)行通信和交流，許多商家和組織機(jī)構(gòu)也用電子郵件進(jìn)行各種商業(yè)活動(dòng)和業(yè)務(wù)聯(lián)系，毫無(wú)疑問(wèn)，電子郵件已經(jīng)逐漸開(kāi)始取代普通的信件，成為為主流的信件交流工具，帶來(lái)的就是電子商務(wù)的發(fā)展。
VisualBasic6.0是微軟開(kāi)發(fā)的一款面向?qū)ο蟮某绦蛟O(shè)計(jì)語(yǔ)言，被廣泛的應(yīng)用各種系統(tǒng)應(yīng)用程序的開(kāi)發(fā)。VB有靈活，高效，易用，功能強(qiáng)大的等特點(diǎn)，所以用VB來(lái)編寫電子郵件收發(fā)系統(tǒng)很合適。郵件收發(fā)系統(tǒng)是個(gè)人軟件，利用個(gè)人電腦的outlook終端進(jìn)行網(wǎng)絡(luò)會(huì)話，相對(duì)的又比outlook郵件系統(tǒng)簡(jiǎn)單實(shí)用。當(dāng)今網(wǎng)絡(luò)上郵件系統(tǒng)多不勝數(shù)，幾乎全是基于Web服務(wù)器的asp系統(tǒng)。用vb編寫郵件系統(tǒng)沒(méi)有Web服務(wù)器支持，所以不能像網(wǎng)絡(luò)上那樣有華美的畫面和各種多媒體功能，用vb編寫的只是一個(gè)郵件客戶端。相比較而言，擁有的確是簡(jiǎn)潔實(shí)用和方便快捷，大大提高了我們的工作效率，節(jié)省了我們的時(shí)間。

The now world E-mail has been person who network life the inside is necessary, believing each perception network to there will be an or many a letter for own electronics mailbox, people passing E-mail proceeding correspondence with exchanges, many company's houses with organizing organization too using E-mail proceeding every kind of business activity with business contacting, beyond all doubtly, E-mail already and gradually starting replacing common letter, becoming for main current exchanges tools, bring of is the development of the electronic commerce.
VisualBasic6.0 is development that a procedure design language of the Microsoft development that face to the object, wasing applied the procedure by extensive and applied every kind of system.The VB has vivid, efficiently, use easily, mighty etc. in function characteristics, so use the VB to weave to write the E-mail receive and dispatch the system very fit.The mail receives and dispatch the system is an outlook terminal personal software, making use of the personal computer to proceed the network conversation, opposite again more simple than outlook mail system practical.Mail system many extremely numbers on the now network, the almost all is the system of asp to base on the server of Web.Write with the vb plait the mail system have no the server of Web supports, so can't resemble there is so fine appearance on the network with every kind of multi-media function, use vb the plait write of just a mail the customer carries.Compare than but speech, own is really Chien's 潔 practical ising fast with the convenience, increases consumedly our work efficiency, saved our time.
