【摘要】 组件重用技术是组件技术的一个重要方面,充分利用这一技术,对于应用系统的开发和软件的升级具有很大的帮助。本文论述了在COM原理和重用结构的基础上,借助于ADO提供的对象和接口,完成更高层次的数据访问组件的封装,从而实现更加具体的功能。文中详细阐述了在VisualC++6.0编程环境下利用ATL开发COM组件的方法,并给出了数据访问组件的部分实现代码。更多还原

【Abstract】 Component reuse is an important part of component technology,making full use of it will help us a lot in our development of application system and upgrade of software.This paper discusses the principle and reuse structure of COM and implements encapsulation of the advanced data access component,implementing the particular functions.The development of COM by using ATL(Active Template Library)is detailed described under Visual (C++)6.0 programming environment in this paper,before commentating part created codes of the data access component.更多还原
