第一步
新建vb工程 新建数据库
第二步
引入数据库环境：
ms activiteX data OBJECTS 2.8 LIBRARY
ms excel 11.0
引入显示控件:
常用的有三个
datagrid：可以直接从表格修改数据库数据 但是不能设置每行的颜色 推荐2st
flexgrid：可以显示数据库数据 只读的
hflexgrid：支持ado 可以设置每行显示数据的颜色 推荐1st
第三步：编写代码 将数据库数据筛选显示到表格控件里面
----------------------------------------------------------------------
下面给出我写的vb连接access 和excel的源代码
