主题：这个是什么意思？

代码如下，设计批量打印条码的时候出现的。

 

Dim doc As New PrintDoc
Dim img As prt.RenderImage
Dim Bar As New BarCodeBuilder
Bar.Symbology = Barpro.Symbology.Code128
Bar.BarRatio = 0.3
Bar.BarHeight = 8
bar.SaveImage(ProjectPath & "Images\BarCode.gif",300)
Doc.Stacking = prt.StackingRulesEnum.InlineLeftToRight
For Each r As Row In Tables("quhuojilu").Rows
    bar.Code = r("取货商品名")
    img = new prt.RenderImage
    img.Image =  bar.GetImage
    Doc.Body.Children.Add(img)
Next
Doc.Preview()

也许有的取货商品名列的值，不符合code128编码的规则。
