摘要: 为了实现对Visual FoxPro操作结果的自动评测,对VFP的表文件格式进行研究,以Visual Studio 2008为开发平台,采用对表文件逐字节读取并解析的方法,开发表文件解析类库,应用该类库读取考生应答文件的操作结果并与标准答案比较,完成自动评分过程。该类库的开发能够自动完成评测过程,提高教学效率,减少教师工作量,具有一定的实用价值。

Abstract: In order to realize the automatic evaluation of the results of operating Visual FoxPro, the VFP table file format is deeply studied. With Visual Studio 2008 as development platform, using the method of reading and parsing table file byte by byte, we developed table file parsing library. Through the comparison of the candidates answer file operating results by the application of the library reading and the standard answer, the library can complete the automatic grading process. The automatic grading process improves the teaching efficiency, reduces the workload of teachers, and is of some practical value.
