摘  要
 隨著計算機網絡技術的不斷發展，利用計算機技術實現無紙化考試，取代傳統的手工考試方式是近年來計算機技術一個非常活躍的研究領域。傳統的考試方式在程序設計類課程考核上已不再適應現代教育的發展，網上考試管理系統恰恰能夠解決這些問題。網絡考試系統是發揮網絡優勢開發的考試軟件，具有模塊控制、組卷靈活、網上考試、網上閱卷和網上 查分等優點。
 在國外一些發達國家網上考試己經得到蓬勃發展，已成為現代教育的有力補充，非常適合個性化學習。在國內，網上考試還處于試點階段，目前的網上考試系統大體采用B/S（瀏覽器/服務器）和C/S（客戶/服務器）兩種模式。
 本文介紹基于VB和C/S方式的網上考試系統的設計與實現，學生可以使用該網上考試軟件進行答題，考試軟件的職能是負責與數據庫和其它對象的通訊。我們開發的控制系統仿真課程上機考試平臺是一個功能強大的平臺，考生所有的抽題、編程、調試、保存和交卷都在上機考試平臺上完成，無需在考試平臺與編程語言之間頻繁切換，這簡化了考生的操作，減少了出現意外的可能，使考生能把全部精力都投入到考試中，有利于檢驗出考生的真實水平，教師平臺可以實現閱卷、運行、組卷和成績統計等功能的一體化，方便教師對學生考試的管理。該系統將應用于我校的控制系統仿真課程考試，對提高教學效果和教學質量以及程序類的考試方式改革均具有極其重要的意義。

Abstract

 With the continuous development of computer and network technology, replacing the traditional manual test with paperless examination by using computer technology is a research focus in recent years. Traditional examination method for programming language courses is no longer adapted to the development of modern education, while network test system can solve this problem. Network test system is a test software with the advantages of network. It has the advantages of module control, auto-generating paper, online examination, online marking and online inquiry, and so on
 Online Examination has been booming in some developed countries. It has become a powerful complement of modern education, and is ideal for individualized learning. In China, online exam is still in trial period. Currently, the online examination system is in general based on B / S (Browser / Server) or C / S (Client / Server) mode.
 The Design and Implementation of Online Examination System based on VB and C/S mode is proposed in this thesis. The candidates can use the online examination system to take the exam. The examination software is responsible for the communication with database and other objects. The examination software developed by us, online examination platform of the control system simulation course, is a powerful platform. All operations of the candidates are finished on the examination platform, including extracting questions, programming, debugging, saving and submitting. The candidates don’t need to switch frequently between the platform and programming language, which simplifies the operation of examination, and reduces the accidents so that the candidates can put all their energies on examinations. Therefore, the scores can reflect the candidates' real ability.  Teachers marking platform include marking, running, generating paper, scores statistics, which is convenient for teachers to manage the examination. The examination platform will be applied to our school's examination of the control system simulation course, which can improve the teaching effectiveness and quality. It is extremely important for the reform of the examination process for the programming language courses.
