Vb.net 如何在Visual Basic中使用多个Windows窗体进行多页双面打印？

我正在设法将多个Windows窗体打印为报表。我有多个表格可以计算我们客户的退休福利，我正试图打印这些表格，以便我们的客户得到救济。此时，我在每个表单上都有一个PrintDocument组件，我可以将每个表单作为不同的文档打印在单独的页面上，但我试图实现的是，用一个打印按钮在一个PrintDocument文档中重复打印所有这些表单。单击另一个表单

给你举个例子。我有两个Windows窗体（FormAOW和FormBasisInfo），每个窗体都有一个PrintDocument组件。我已经绘制了文本、图像、图表等。按照打印文档1_PrintPage sub中的正确位置绘制。我想在第三个表单CloseReport中打印表单AOW和基本信息

我已有的代码没有双面打印：

基本信息：

Public Class Basisinfo


Private Sub Button2_Click(sender As Object, e As EventArgs) Handles ButtonPrinten.Click

    For teller = 1 To 30
        If inhoudlijst(teller, 0) = "" Then
            inhoudlijst(teller, 0) = "Basisinfo"
            inhoudlijst(teller, 1) = "True"
            PrintDocument1.DefaultPageSettings.Landscape = True
            PrintDocument1.DefaultPageSettings.PrinterSettings.Duplex = Printing.Duplex.Default
            printarray3(teller) = PrintDocument1
            Exit For
        End If
    Next
End Sub


Private Sub PrintDocument1_PrintPage(sender As Object, e As Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

    Dim stringFormatCenter As New StringFormat()
    stringFormatCenter.Alignment = StringAlignment.Center
    stringFormatCenter.LineAlignment = StringAlignment.Center

    Dim stringFormatFar As New StringFormat()
    stringFormatFar.Alignment = StringAlignment.Far
    stringFormatFar.LineAlignment = StringAlignment.Center

    Dim stringFormatNear As New StringFormat()
    stringFormatNear.Alignment = StringAlignment.Near
    stringFormatNear.LineAlignment = StringAlignment.Center


    'Alle TextBoxes met witte achtergrond
    For Each TextBox In {TextBox17, TextBox18, TextBox35, TextBox1, TextBox29, TextBox2, TextBox3, TextBox4, TextBox12, TextBox13, TextBox10, TextBox9, TextBox26, TextBox8, TextBox7, TextBox16, TextBox21, TextBox14, TextBox28, TextBox27, TextBox6, TextBox23, TextBox19, TextBox31, TextBox24, TextBox25, TextBox30, TextBox15, TextBox34, TextBox22, TextBox20, TextBox33, TextBox32}
        e.Graphics.DrawRectangle(Pens.Black, New Rectangle(TextBox.Left, TextBox.Top, TextBox.Width, TextBox.Height))
        e.Graphics.FillRectangle(Brushes.White, TextBox.Left, TextBox.Top, TextBox.Width, TextBox.Height)
    Next

    'Alle TextbBoxes met gele achtergrond
    For Each TextBox In {TextBox17, TextBox18, TextBox35, TextBox1, TextBox29}
        e.Graphics.FillRectangle(Brushes.LightYellow, TextBox.Left, TextBox.Top, TextBox.Width, TextBox.Height)
    Next


    'Textboxes Centered
    For Each TextBox In {TextBox17, TextBox18, TextBox35, TextBox1, TextBox29}
        e.Graphics.DrawString(TextBox.Text, TextBox.Font, Brushes.Blue, New Rectangle(TextBox.Left, TextBox.Top, TextBox.Width, TextBox.Height), stringFormatCenter)
    Next

    'Textboxes Near
    For Each TextBox In {TextBox2, TextBox3, TextBox4, TextBox12, TextBox13, TextBox10, TextBox9, TextBox26, TextBox8, TextBox7, TextBox16, TextBox21, TextBox14, TextBox28, TextBox27, TextBox6, TextBox23, TextBox19, TextBox31, TextBox24, TextBox25, TextBox30, TextBox15, TextBox34, TextBox22, TextBox20, TextBox33, TextBox32}
        e.Graphics.DrawString(TextBox.Text, TextBox.Font, Brushes.Blue, New Rectangle(TextBox.Left, TextBox.Top, TextBox.Width + 20, TextBox.Height), stringFormatNear)
    Next


    'Textboxes Far
    For Each TextBox In {}
        e.Graphics.DrawString(TextBox.Text, TextBox.Font, Brushes.Blue, New Rectangle(TextBox.Left, TextBox.Top, TextBox.Width, TextBox.Height), stringFormatFar)
    Next



    For Each c As Control In Me.Controls
        If c.GetType Is GetType(Label) Then
            e.Graphics.DrawString(c.Text, c.Font, Brushes.Black, c.Left, c.Top)
        End If
    Next
End Sub

AOW:

关闭报告：

Public Class CloseReport


Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

    PrintDocument1.DefaultPageSettings.Landscape = True
    PrintDialog1.Document = PrintDocument1
    If PrintDialog1.ShowDialog() = DialogResult.OK Then
        For teller = 1 To 30
            If IsNothing(printarray3(teller)) = False Then
                printen6(printarray3(teller))
            End If
        Next teller
    End If
End Sub
End Class

如果您想知道printen6函数的功能：

    PrintDocument.PrinterSettings.DefaultPageSettings.PrinterResolution.Kind = Printing.PrinterResolutionKind.High
    PrintDocument.PrinterSettings.DefaultPageSettings.Landscape = True
    PrintDocument.PrinterSettings.DefaultPageSettings.Margins = New Printing.Margins(0, 0, 0, 0)

    PrintDocument.DefaultPageSettings.PrinterSettings.Duplex = Printing.Duplex.Default


    PrintDocument.Print()

我正在考虑如何合并PrintDocument文件以实现双面打印，或者如何使用HasMorePages创建多个页面。我读过很多关于HasMorePages的文章，但这只提供了加载文本文件的代码

---

我希望你能帮助我，因为我真的被困在这件事上了。提前谢谢

对于那些对答案感兴趣的人来说：这是e.HasMorePages=True。。但唯一缺少的是一个（公共）的“页码”计数器，它可以在两种情况之间进行选择对于e.HasMorePages来说，到达子页面的末尾很重要。否则就没有效果了。请参阅下面的代码

有人能帮帮我吗？我在寻找一种不用读文本文件就能进行双面打印的方法。我需要打印表单上的控件，而不是文本文件阅读器。每个表单都有足够的控件放在正确的位置，以完全填充页面。控件是图表和组框的位图，还有文本框和标签。仍然没有找到解决我问题的方法。有人能帮我吗？有人能帮我吗？我在寻找一种不用读文本文件就能进行双面打印的方法。我需要打印表单上的控件，而不是文本文件阅读器。每个表单都有足够的控件放在正确的位置，以完全填充页面。控件是图表和组框的位图，还有文本框和标签。仍然没有找到解决我问题的方法。有人能帮我吗？
