一般是在ACCESS或是SQLSERVER中查寻，或是汇总，然后生成一个‘记录集’可以显示在GRID里，也可以将这个记录集导出到磁盘中。
下面可以导出Xls,DBF,DB,MDB(表）,这些功能是由ISAM数据库接口实现，为了导出各种版本的文件，我在MS网站了最新的JET4和MDAC6。前者到用于桌面数据库如ACCESS，FOXPRO的组件，后者是实现新版本ADO组件。分别在：
http://download.microsoft.com/download/access2000/SP/4.0/NT5/EN-US/Jet40SP5_W2K.exe
http://download.microsoft.com/download/dasdk/install/2.60.6526.3/WIN98Me/CN/mdac_typ.exe
这些是标准的SQL导出语句：
select * into [Excel 8.0;database=导出目录].导出表名 from 表
select * into [FoxPro 2.6;database=导出目录].导出表名 from 表
select * into [FoxPro 2.5;database=同上].导出表名 from 表
select * into [dBase III;database=同上].导出表名 from 表
select * into [Paradox 4.X;database=同上].导出表名 from 表
select * into [;database=C:\temp\xxx.mdb].导出表名 from 表
下面程序为实现用户自定议文件名用变量代替一部分。
