你好，请教一下，像这种事件（导入
要排除其它列重复数据）的代码，写在哪里才是正确的。
Dim Book As New
XLS.Book("c:\test\订单.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("订单").StopRedraw()
Dim nms() As String = {"编号","产品","客户","雇员","单价","折扣","数量","日期"}
For
n
As
Integer = 1
To
Sheet.Rows.Count -1
Dim
bh
As
String = sheet(n,0).Text
Dim
dr
As
DataRow = DataTables("订单").Find("编号 = '" &
bh
& "'")
If dr Is Nothing Then
'如果不存在同编号的订单
dr = DataTables("订单").AddNew()
End If
For
m As Integer = 0 To nms.Length - 1
dr(nms(m)) = Sheet(n,m).Value
Next
Next
Tables("订单").ResumeRedraw()
