有很多方法都可将数据库中某个表的数据导出到电子表格中,例如通过创建Access.Application,可以利用Access本身的导出功能实现将表中的数据导出到电子表格中。但是这种方法会占用较多的系统资源,并且缺乏通用性。如果一个数据库没有导出的功能怎么办?下面的这段程序代码利用记录集实现导出的功能,这种做法的好处是显而易见的:你可以控制要导出的数据,而不用将整个表的内容都导出到电子表格中。为简单起见下面的程序代码仍将整个表的数据导出到电子表格中。如果你有兴趣的话,对下面的代码稍加改动就可做成更为通用的一个类或是一个控件。 首先在窗体上添加一个标签控件和一个命令按钮,然后在工程中添加对DAO引用。利用下面的程序代码就可将表中的数据导出到电子表格中。Option ExplicitPrivate Sub Command1_Click() Dim tempDB As Database Dim i As Integer ' 循环计数器 Dim j As Integer Dim rCount As Long ' 记录的个数 Dim xl As Object ' OLE自动化对象 Dim Sn As Recordset Screen.MousePointer = 11 Label1.Caption = "打开数据库..."
