轉:VB6中将数据导出到Excel提速之法
from : http://www.it86.cc/develop/2008/0410/28928.shtml
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。
在程序中引用Microsoft Excel 9.0 Object Library，将下文加入到一个模块中,窗体中调用如下ExporToExcel("select * from table")。则实现快速将数据导出到EXCEL中。
