VB在工程制图CAI系统中的应用

APPLICATION OF VISUAL BASIC IN CAI SYSTEM OF ENGINEERING DRAWING

以工程制图 CAI为例,介绍了对 VB开发的必要性和模块化的设计思想,并论述了用VB实现图形显示、音频和动画播放及外部程序调用的方法。

Multimedia teaching has an important significance in the field of education, which is becoming an essential teaching tool along with the development of the computer technique. Meanwhile, with the development of the network, multimedia technique is also becoming maturity day by day. This article has taken example for CAI (Computer-aided instruction) system of engineering drawing, in which introduced the necessity of this software in development and the designing idea of modularization, moreover, discussed the graph display, audio frequency and cartoon broadcasting using VB (Visual Basic), and the method of transfer of external process.
