摘要
Visual Basic是目前常用于Windows程序设计的优秀编程语言之一,在今后有关程序设计普及及培训和考核中势必占据越来越重要的地位.为了考核学生应用VB编写程序的能力,实现Visual Basic试题的自动评阅,开发了一个针对Visual Basic上机考试的自动阅卷系统.对Visual Ba-sic和Windows的消息处理机制进行了深入地研究,对动态链接库技术在本系统中发挥的作用进行了分析,提出了VB中动态调用动态链接库的方式,既实现了试题库及试题答案的可扩充性,又实现了程序功能的可扩展性和易维护性.同时还阐述了VB题型的自动阅卷的实现过程.
Visual Basic is an excellent programming language commonly used in Windows. In the future, it will be more important in training and examinations of computer programming. In order to grade the programming ability of students with Visual Basic, an automatic marking system for Visual Basic programming has been developed. The principles of Visual Basic and Windows message handling mechanism were studied, the role of DLL techniques in the system was analyzed, and the method of calling DLL dynamically in Visual Basic was introduced. The exam problem and solution databases are expandable, and the system functions can be easily expanded and maintained. In addition, the working process of the automatic examination marking system was also discussed.
