Access导出到Excel提速之法

Visual Basic 导出到Excel 提速之法

Excel 是一个非常优秀的报表制作软件，用VBA可以控制其生成优秀的报表，本文通过添加查询语句的方法，即用Excel中的获取外部数据的功能将数据很快地从一个查询语句中捕获到EXCEL中,比起往每个CELL里写数据的方法提高许多倍。

将下文加入到一个模块中,屏幕中调用如下ExporToExcel("select * from table"则实现将其导出到EXCEL中

Public Function ExporToExcel(strOpen As String)

'*********************************************************

'* 名称：ExporToExcel
