小弟经常查看数据库里面的数据查看表数据，要用对sql server 要有企业管理器或查询分析器
对oracle 用 sql plus ， 来回切换真麻烦，于是编了一个数据库查看器
只针对 ms sql server 和 oracle 数据库，采用oledb连接数据库
本程序为VB程序，使用了
Microsoft Internet Controls 和 Microsoft Windows Common Controls 6.0的控件库
此外还引用了 Microsoft ActiveX Data Objects 2.5 Library ,
Microsoft OLE DB Service Component 1.0 Type Library 的引用
