'申明变量
Dim xlApp As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Set xlApp = CreateObject("Excel.Application")
'使用模板
Set xlBook = xlApp.Workbooks.Open(App.Path & "\普通.xls")
On Error GoTo 0
Set xlSheet = xlBook.Worksheets(1)
xlApp.Visible = False
xlSheet.Activate
'处理数据,填充Excel表
xlSheet.Cells(3, 4) = TextQuery.Text '产品名称
……
'//////////////
xlApp.Visible = True '显示表格
Set xlApp = Nothing '交还控制给Excel
Set xlBoook = Nothing
Set xlSheet = Nothing
到此，导出到Excel完成，在.NET中，只需改动少许即可运行，只是C#的语法有些区别
