主题：[求助]如何对指定行或者当前表来打印二维码

这是产品二维码打印代码。但是这个打印是把所有状态为Published的都打印出来了。

正常情况打印应该为指定行或者当前表来打印。请问Tables("商务下单查询表").Filter="状态 = 'Published'"怎么改才符合要求。、

做成对指定行打印show_version，和批量打印当前表的show_version.

 

Tables("商务下单查询表").Filter="状态 = 'Published'"
Dim pdf As New PrintDoc
Dim rg As prt.RenderGraphics
Dim Bar As New BarCodeBuilder
Bar.Symbology = Barpro.Symbology.QRCode
pdf.Stacking = prt.StackingRulesEnum.InlineLeftToRight
For Each r As Row In Tables("商务下单查询表").Rows
    bar.Code = r("show_version")
    rg = new prt.RenderGraphics
    bar.DrawOnCanvas(rg.Graphics,0,0,1)
    rg.Style.Spacing.All = 3
    pdf.Body.Children.Add(rg)
Next
pdf.Preview()

不是很理解你的意思呢.

 你说的指定行是什么意思？是选中的行？还是现在表里看到的所有行？

需要做2个打印二维码的按钮。

一个是指定行二维码打印，指定行的意思是就是选中其中的一行。

第二个是批量打印二维码，意思是只针对当前表。

 第一个按钮

Dim pdf As New PrintDoc
Dim rg As prt.RenderGraphics
Dim Bar As New BarCodeBuilder
Bar.Symbology = Barpro.Symbology.QRCode
pdf.Stacking = prt.StackingRulesEnum.InlineLeftToRight
Dim r As Row = Tables("商务下单查询表").Current
    bar.Code = r("show_version")
    rg = new prt.RenderGraphics
    bar.DrawOnCanvas(rg.Graphics,0,0,1)
    rg.Style.Spacing.All = 3
    pdf.Body.Children.Add(rg)
pdf.Preview()

第二个按钮

Dim pdf As New PrintDoc
Dim rg As prt.RenderGraphics
Dim Bar As New BarCodeBuilder
Bar.Symbology = Barpro.Symbology.QRCode
pdf.Stacking = prt.StackingRulesEnum.InlineLeftToRight
For Each r As Row In Tables("商务下单查询表").Rows
    bar.Code = r("show_version")
    rg = new prt.RenderGraphics
    bar.DrawOnCanvas(rg.Graphics,0,0,1)
    rg.Style.Spacing.All = 3
    pdf.Body.Children.Add(rg)
Next
pdf.Preview()
