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.

Key words: test system, key technology, table file, format analysis, VFP
