大师，在导入的时候一直会提示一个错误，

下面是导入的代码：

Dim dlg As New OpenFileDialog
dlg.Filter= "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog = DialogResult.Ok Then
    If FileSys.FileExists(dlg.FileName) Then
        Dim Book As New XLS.Book(dlg.FileName)
        Dim Sheet As XLS.Sheet = Book.Sheets(0)
        Tables("main").StopRedraw()
        \'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
        Dim nms() As String = {"jieshoujigou","changjia","songdanwei","xinghao","xuliehao","beijianid","guzhang"}
        \'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
        For n As Integer = 1 To Sheet.Rows.Count -1
            Dim bh As String = sheet(n,0).Text
            If DataTables("main").Find("xuliehao = \'" & bh & "\'") Is Nothing Then \'如果不存在同编号的订单
                Dim r As Row = Tables("main").AddNew()
                For m As Integer = 0 To nms.Length - 1
                    r(nms(m)) = Sheet(n,m).Value
                Next
            End If
        Next
        Tables("main").ResumeRedraw()
    End If
End If

错误提示：怎么修改一下代码？

 看看你Datacolchanging里面写了什么代码。

 这样调试一下 http://www.foxtable.com/help/topics/1485.htm
