打印多个页面

Question

我正在从VB5转换，并试图获得相当于VB.NET中的printer.NewPage。 我的代码如下，但它只是在单个页面上打印两行。 程序打印两页计算结果（数组等），它不读取和打印文件。 如何获得第二页？

Private Sub PrintGeneralReport() 

    Dim PrintPreviewSelected As Boolean = True 

    'Set the doc to print 
    Dim pDoc As New PrintDocument 
    pDoc.PrintController = New StandardPrintController 'turns off the printing page x of y dialog 

    'Get the printer to use 
    If Me.PrintDialog1.ShowDialog() = DialogResult.OK Then 
     pDoc.PrinterSettings.PrinterName = Me.PrintDialog1.PrinterSettings.PrinterName 
     'pDoc.DefaultPageSettings.Margins = New Margins(75, 50, 50, 50) 
     pDoc.DefaultPageSettings.Margins = New Margins(40, 10, 10, 10) 
     pDoc.OriginAtMargins = True 

    Else 
     pDoc = Nothing 
     Exit Sub 
    End If 

    ' Install the PrintPage event handler. 
    AddHandler pDoc.PrintPage, AddressOf PrintGenReport 

    If PrintPreviewSelected Then 
     ''print preview 
     PrintPreviewDialog1.Document = pDoc 
     PrintPreviewDialog1.UseAntiAlias = True 
     PrintPreviewDialog1.WindowState = FormWindowState.Maximized 
     PrintPreviewDialog1.ShowDialog() 
    Else 

     'just print 
     pDoc.Print() 
    End If 

    RemoveHandler pDoc.PrintPage, AddressOf PrintGenReport 

End Sub 

Private Sub PrintGenReport(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) 

    Dim fnt10 As Font = New Font("Courier New", 10, FontStyle.Regular) 
    e.Graphics.DrawString("Page 1", fnt10, Brushes.Black, 20, 100) 
    'ROARK1.Print_GeneralReportRK(Me, e) 
    e.HasMorePages = True 
    e.Graphics.DrawString("Page 2", fnt10, Brushes.Black, 20, 200) 
    'ROARK1.Print_MemberActions(e) 
    e.HasMorePages = False 
End Sub

试试这个：

Private PageNum As Integer = 1 

Private Sub PrintGenReport(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) 
    Dim fnt10 As Font = New Font("Courier New", 10, FontStyle.Regular) 
    e.Graphics.DrawString("Page " & PageNum.ToString(), fnt10, Brushes.Black, 20, 100 * PageNum) 

    e.HasMorePages = (PageNum < 2) 
    PageNum += 1 
End Sub 

注意PageNum变量在类级别定义。您还应该在PrintGeneralReport()方法中添加一行，以便在每个打印作业开始时将其重新设置为1。
