摘要
该文叙述了当前的软件二次开发方法的不足，介绍了多任务操作系统的消息驱动机制和以消息为纽带的软件二次开发方法，以及以这种方法开发ＭＢＰ程序的步骤。最后作者以ＡｕｔｏＣＡＤ为例，介绍了在ＷＩＮＤＯＷＳ多任务操作系统工作平台下，一个机械ＣＡＤ系统的应用开发实例。
This paper presents the deficiency of current quadratic exploit and explains the message driving mechanism of multiple tasks operating system and quadratic exploit based message.It also Gives the programming steps of MBP development In addition,using AutoAD as example,the paper describes application of mechanical CAD under Windows multiple tasks operating desktop.
