摘要
本文提出了设计《电子技术基础》课程试题库的一种简便、实用的方法。这种方法的特点是在CCBIOS2.13H汉字系统支持下,将电路图、电信号波形图等图形“字符化”,使本无图形处理能力的FoxBASE+关系数据库管理系统以处理字符方式处理图形,充分发挥其管理功能强的特点,使程序设计变得十分简单;利用CCBIOS2.13H的预选汉字输入功能和Wordstar字处理软件的文件调用功能实现了试题图形的快速输入,解决了建库工作量大的问题。应用程序的灵活编辑功能使打印出的试卷格式规范,文字和图形清晰美观。
This paper present a conviment and practical method for the design of the Item Bank of the course 《EIectronic Techonology Foundamentals》. A characteristic of this method is transforming the circuit diagram and signal waveform to a kind of text character, on the support of CCBIOS 2.13H, as to make the FoxBASE+Relational Data Base Managing System powerful managing capacity, which originally has not the graphic function, also the programming extremely simple. The inputting graphics at high speed is achieved based on the preselected Chinese character inputting function of CCBIOS 2.13H and files transferring function of Wordstar software, and the problem of the large amount of work frequently arising in the case of creating Data Base is solved. The flexible editting function of the FoxBASE program provided in this paper makes the form of the printed examination paper standard, and gives a clear and artistic output of text and graphics.
