Visual LISP环境下面向对象的编程技术

Visual LISP是在AutoLISP基础上发展起来的一种新的、功能强大的可视化编程环境，其中提供了面向对象的编程技术，通过它可以用编程的方式直接操作AutoCAD图形数据库，程序运行效率及安全性大大提高。对象模型、对象方法和属性是Visual LISP面向对象编程技术的基础，ActiveX函数的灵活运用是实现Visual LISP面向对象编程的关键。通过实例介绍了怎样获得对象模型、对象方法和属性，ActiveX函数的使用以及灵活运用ActiveX函数进行CAD应用程序的设计。

Cater to Object Programing Technique for Computer Under the Environment of Visual LISP

Visual LISP is a new and function\|extended visual programing environment for Computer.It provides a cater to object programing technique for computer.With the technique,the AutoCAD graph database can be directly operated by the way programing for computer and the efficiency of programing operation and the safety are greatly improved.The object model,object method and attribute are the basis of Visual LISP cater to object programing technique for computer,flexible operation of ActiveX function is the key for realize this technique.By examples,it shows how to get the object model,object method and attribute,as well as the application of ActiveX function and CAD applied program design by flexile operation of ActiveX function.
