vb连接access excel步骤 excel 导入access

前端之家收集整理的这篇文章主要介绍了vb连接access excel步骤 excel 导入access前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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
