基于Visual Basic的ASP组件的开发

Developing ASP Components Based on Visual Basic

组件是对数据和方法的简单封装，组件有自己的属性和方法，使用组件可以实现拖放式编程、快速的属性处理以及真正的面向对象的设计。组件技术日益成为软件开发新技术。本文详细介绍了动态网页开发中使用ASP组件的优势，ASP组件的特点。开发的工具以及一般开发流程。并以文件读取ASP组件为例，对Visual Basic中组件的开发作了具体阐述，并应用于Web应用程序。本文对了解ASP组件构成，以及利用组件进行三层应用程序开发有很好的借鉴作用。

Component, which is the simple encapsulation of data and method, has its own attribute and methodology. It can be used to achieve drag-and-drop programming, instant attribute manipulation and genuine object-oriented programming, Component technique is becoming the technique of nowadays in the discipline of software develop-ment. This passage detailedly introduces advantages and characteristics of ASP components as well as design tools and general design procedures in dynamic web construction. With examples of data-input ASP component, the components development of Visual Basic have been amply described and introduced into Web Application,The passage presents sufficent and good references for comprehending the component composition of ASP and their application to 3-layer-prograrn-development.
