vb连接access excel步骤 excel 导入access

第一步

新建vb工程 新建数据库

第二步

引入数据库环境：

ms activiteXdata 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
