经过前面系统分析和数据库设计,文章管理系统的基本设计环境已经建立起来了,按照管理信息系统设计的环节,现在已经进入了系统实施阶段。本系统拟采用Visual Studio.NET2003设计。使用Visual Studio.NET2003新建一个Web应用程序 ，命名为TheArticleSYS，具体步骤略。下面，我们按照数据信息积累分先后顺序详细介绍本系统的设计与编写。首先是后台管理部分，然后是前台浏览和检索部分。
14.3.1 Admin_Management.aspx的设计与编码
为了系统界面更加紧凑，我们把后台管理部分的文章分类管理功能模块和文章信息管理功能模块集成到Admin_Management.aspx窗体内，并提供了文章发布的入口。
Admin_Management.aspx窗体的前台HTML代码如下：
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="Admin_Management.aspx.vb" Inherits="TheArticleSYS.Admin_Management"%>
