How do you set the Crystal Report Viewer Printer to Duplex

Question

Using the code below I can print in duplex mode, but this does not let me view a report before printing
How do I set the Printer in the Viewer Control Bar of the Crystal Report Viewer to Duplex Printing programmatically rather than having to manually select Duplex through the preferences option?
I have searched but the only example code I found produces errors in the code and will not run
Private myReport As ReportDocument
myReport = New ReportDocument()
myReport.PrintOptions.PaperSize = PaperSize.PaperA4
myReport.PrintOptions.PaperOrientation = PaperOrientation.Portrait
myReport.PrintOptions.PrinterDuplex = PrinterDuplex. Vertical
myReport.PrintToPrinter(3, False, 0, 0)
In my VB6 Project that I am converting to VB.NET when I added Report.PrinterDuplex = crPRDPVertical, this allowed me to view the report and then print with Duplex without having to set the Print Preferences manualy
I found 1386475 - How to set printer name and print job title at runtime using Report Application Server SDK for Visual Studio .NET
But this causes errors
Imports CrystalDecisions.ReportAppServer.ClientDoc
Imports CrystalDecisions.ReportAppServer.Controllers
Dim boReportClientDocument As ISCDReportClientDocument
Dim boPrintOutputController As PrintOutputController
Dim boPrintReportOptions As New PrintReportOptions

Hi David,
You can mix both engines, just declare them both with different report object names. Here's all of my references:
using System;
using System.IO;
using System.Xml;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.ReportDefModel;
using CrystalDecisions.ReportAppServer.CommonControls;
using CrystalDecisions.ReportAppServer.CommLayer;
using CrystalDecisions.ReportAppServer.CommonObjectModel;
using CrystalDecisions.ReportAppServer.ObjectFactory;
using System.Data.OleDb;
using CrystalDecisions.ReportAppServer.DataSetConversion;
using CrystalDecisions.ReportAppServer.DataDefModel;
using CrystalDecisions.ReportSource;
using CrystalDecisions.Windows.Forms;
using System.Data.SqlClient;
using System.Runtime.InteropServices;
    public class frmMain : System.Windows.Forms.Form
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc;
My file open dialog:
        private void btnOpenReport_Click(object sender, System.EventArgs e)
            rptClientDoc = new CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocument();
            openFileDialog.Filter = "Crystal Reports (*.rpt)|*.rpt|Crystal Reports Secure (*.rptr)|*.rptr";
            openFileDialog.FilterIndex = 1;
             if (openFileDialog.ShowDialog() == DialogResult.OK)
                  btnOpenReport.Enabled = false;
                  btnSaveRptAs.Enabled = false;
                  object rptName = openFileDialog.FileName;
                try
                    rpt.Load(rptName.ToString());
                    rptClientDoc = rpt.ReportClientDocument;
                catch (Exception ex)
                    MessageBox.Show("ERROR: " + ex.Message);
                    return;
                MessageBox.Show(rptClientDoc.MajorVersion.ToString() + "." + rptClientDoc.MinorVersion.ToString());
                    MessageBox.Show("Report opened.","RAS",MessageBoxButtons.OK,MessageBoxIcon.Information );
                    btnOpenReport.Enabled = true;
                    btnSaveRptAs.Enabled = true;
                //MessageBox.Show(rpt.RecordSelectionFormula, "my record: ", MessageBoxButtons.OK, MessageBoxIcon.Information);
                MessageBox.Show(rpt.ReportRequestStatus.NumberOfPages.ToString(), "Number of Pages: ", MessageBoxButtons.OK, MessageBoxIcon.Information);
As for the page number I use it off the Engine report object:
MessageBox.Show(rpt.ReportRequestStatus.NumberOfPages.ToString(), "Number of Pages: ", MessageBoxButtons.OK, MessageBoxIcon.Information);
And it works for me...
Thank you
Don
