上机考试系统主要应用于计算机基础上机考试,是从小学到大学及社会上计算机水平测试均涉及的一门考试,该考试的目的在于让学生掌握计算机系统的操作方法和文字处理软件的应用等。本文的主要目的就是设计一个上机考试系统,实现上机考试的自动出题和自动判分。
论文首先介绍了VBA语言和VB语言的基础知识,论证其作为开发语言的可能性、优越性;然后介绍了word对象结构模型,详述了Word Basic和Visual Basic的区别和转换。接下来以word为实例对整个上机考试系统进行了总体设计,分析了出题系统和判卷系统的实现方法;重点叙述了上机考试系统功能的实现,其中出题系统主要综合了随机选题和事先设定两种方法来选题,而判卷系统除实现了自动评分外还实现了批处理和调用Excel统计成绩的功能。最后通过对任务栏编程技术的研究,对本上机考试系统实现了托盘技术,在托盘技术中主要应用回调函数来处理任务栏提示区的消息。论文着重对自己所做的部分进行了详细的描述;基于整体的需要,对功能实现部分给出部分代码。

Start up to examine the system to mainly be apply in the calculator foundation to start up the examination, learn an examination that the university and the society calculator level tests all involve since the childhood, the purpose that should examine lies in applied etc. of the operation method and the word processing software that let student control the calculator system.The textual and main purpose is to design a starts up to examine the system, the realization starts up the examination of make out questions automatically and judge the cent automatically.
The thesis introduced the foundation knowledge of the language of VBA and the VB language first, argument it is the possibility, superiority of the development language;Then introduced the word object structure model, go into detail the Word Basic and the differentiation of the Visual Basics and convert.Connect down with word for solid example to whole started up to examine the system to carry on the total design, analyze to make out questions the system and judge a system to carry out method;The point describes to start up the realization of examine the system function, among them make out questions the system to mainly synthesize to choose random and set two kinds of methods in advance to choose, but judge a system to still carried out to criticize the processing and adjust the function that statisticses the result with the Excel in addition to carrying out the automatic grade point.Pass finally to the technical research of the mission column plait distance, started up to examine the system to carry out the tray technique to the origin, the main application returns to adjust the function in the tray technique to handle the news that the mission column hints the area.The thesis emphasize to oneself do of part carried on the detailed description;According to the whole demand, carry out part to a parts of codes to the function.
