摘 要

如今基于構(gòu)件的軟件復(fù)用和開(kāi)發(fā)被認(rèn)為是提高軟件生產(chǎn)率和軟件質(zhì)量的有效途徑。一般來(lái)說(shuō)，基于構(gòu)件的軟件復(fù)用包括三個(gè)相關(guān)的過(guò)程：構(gòu)件的開(kāi)發(fā)，構(gòu)件的管理和基于構(gòu)件組裝的系統(tǒng)開(kāi)發(fā)。在基于構(gòu)件的軟件開(kāi)發(fā)中，系統(tǒng)開(kāi)發(fā)的重點(diǎn)從系統(tǒng)設(shè)計(jì)變成構(gòu)件組裝。本文研究的就是這種基于構(gòu)件的軟件自動(dòng)組裝技術(shù)。
開(kāi)發(fā)該系統(tǒng)，我使用面向?qū)ο蟮目梢暬_(kāi)發(fā)工具Visual Basic 6.0，運(yùn)用計(jì)算機(jī)軟件技術(shù)和面向?qū)ο蟮能浖_(kāi)發(fā)方法。首先制作出用于模擬構(gòu)件的芯片（芯片的部分內(nèi)部功能由指導(dǎo)老師提供），其次設(shè)計(jì)出一個(gè)相對(duì)比較簡(jiǎn)單的連接件（因連接件的開(kāi)發(fā)另有同學(xué)研究），最后采用事件觸發(fā)的方法，運(yùn)用連接件實(shí)現(xiàn)模擬構(gòu)件（芯片）間的組裝，同時(shí)，實(shí)現(xiàn)功能芯片間的模擬防真。
通過(guò)該系統(tǒng)的研究開(kāi)發(fā)，使我獲益匪淺，不但對(duì)基于構(gòu)件的軟件自動(dòng)組裝技術(shù)有了更深刻的認(rèn)識(shí)，而且對(duì)開(kāi)發(fā)工具Visual Basic 6.0有了更全面的掌握。當(dāng)然，限于作者水平，本系統(tǒng)難免有疏漏和不完善之處，敬請(qǐng)各位老師不吝指正。

Abstract

Now component-based software reuse and development is considered as an effective and efficient approach to improve the productivity and quality of software development. Generally, component-based software reuse includes three processes: component development, component management and system development which is based on component composition. In the component-based software development, the emphasis of system development has been turned to component composition from system design. This text is studying the technology of component-based software composition automatically.
In order to develop this system, I used the objected-oriented visual tool Visual Basic 6.0 , computer software technology and the method of objected-oriented software development .Firstly, I developed the chips whose some interior functions were offered by the teacher to simulate components. Secondly, I developed a simple connective-ware , because there was another student studied it specially. Finally, I let the system come true with the method of event-driven and connective-ware, simultaneity, these chips could simulate the truth.
By developing this system, I benefit a lot, not only understand the technology which component-based software composition automatically even more, but also master the tool Visual Basic 6.0 to develop software even more comprehensive. Certainly, limited to the author, this system was hard to avoid oversights and faultiness, please every teacher point out unstinted.

Keywords：component; software component; connective-ware; software reuse; component composition

1引言
1.1研究的必要性
現(xiàn)如今，隨著軟件系統(tǒng)的復(fù)雜性不斷增長(zhǎng)、軟件人員的頻繁流動(dòng)和軟件行業(yè)的激烈競(jìng)爭(zhēng)等因素的出現(xiàn)，軟件企業(yè)迫切需要提高軟件質(zhì)量、積累和固化知識(shí)財(cái)富,并盡可能地縮短軟件產(chǎn)品的開(kāi)發(fā)周期。于是集軟件復(fù)用、分布式對(duì)象計(jì)算、企業(yè)級(jí)應(yīng)用開(kāi)發(fā)等技術(shù)為一體的"基于構(gòu)件的軟件開(kāi)發(fā)"(CBSD,Component Based Sortware Development)應(yīng)運(yùn)而生，這種技術(shù)以軟件架構(gòu)為組裝藍(lán)圖,以可復(fù)用軟件構(gòu)件為組裝模塊,以連接件為組裝紐帶，支持組裝式軟件的復(fù)用,從而大大提高了軟件生產(chǎn)效率和軟件質(zhì)量。這正是研究本課題的意義所在。
1.2高級(jí)語(yǔ)言的選擇
根據(jù)本課題的特點(diǎn)，我選擇了一種面向?qū)ο蟮母呒?jí)語(yǔ)言——Visual Basic 6.0。
選用Visual Basic 的原因：
