Upgarding Crystal Reports for VB6 to C# 2010

Question

I am faced with upgrading crystal reports written for VB6 to be used by C# in VS2010 (Crystal Reports 13)
Please provide me with links to good working practise in making this upgrade. The back-end database is SQL Server 2005 and is accssed by stored procedures and a data layer. The data layer which was previously written in ADO/VB6 is now being re-written to ADO.NET/C#.

Hi Clive,
If you open those sample applications it will answer a lot of your questions for upgrading and how to open reports.
When you open a project created in VS .NET and upgrade CR .NET assemblies VS will simply prompt you if you want to upgrade the runtime. All assembly versions in .NET will show for example 13.0.2000.0, these never change, just the file version itself will change with patches. No rebuild required, although recommended just in case.
As for how to open a report it's pretty much the same as the RDC:
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 System.Threading;
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;
namespace Unmanaged_RAS10_CSharp_Printers
     /// <summary>
     /// Summary description for Form1.
     /// </summary>
     public class frmMain : System.Windows.Forms.Form
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc;
RPT is the Engine and can do basic API's and ISCDReportClientDocument is RAS and has all functionality available in API's, or as much as documented in the Help files.
This uses A dialog box to open reports:
          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";
            //openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
            openFileDialog.FilterIndex = 1;
            //rptClientDoc.MinorVersion();
               if (openFileDialog.ShowDialog() == DialogResult.OK)
                    btnOpenReport.Enabled = false;
                    btnSaveRptAs.Enabled = false;
                btnCloserpt.Enabled = false;
                    object rptName = openFileDialog.FileName;
                try
                    rpt.Load(rptName.ToString(), OpenReportMethod.OpenReportByTempCopy);
