表A为临时表，其中有一列编号，希望在excel报告中生成条形码，代码以下，会出现错误，请问如何处理？
Dim Book As New XLS.Book(ProjectPath & "Attachments\ReportLabel.xls")
Dim fl As String = ProjectPath & "Reports\LaberNo.xls"
For Each r As Row In Tables("表A").Rows '逐行生成报
Dim Bar As New BarCodeBuilder
Bar.Symbology = Barpro.Symbology.Code39
Bar.Code = r("编号")
Bar.BarRatio = 0.3
Bar.BarHeight = 8
bar.SaveImage(ProjectPath & "Images\myimg.wmf",300)
Book.Build() '生成细节区
Book.Save(fl) '保存工作簿
Next
Dim Proc As New Process '打开工作簿
Proc.File = fl
Proc.Start()
如图，生成的代码也是错误的，请问应该如何处理？
