Question

I have a form that allows a user to select what report they want to generate. They can also select criteria, select Print, Preview, export, etc. After the user makes their selections and clicks the “Generate” button, I have a class that creates the report object, loads the report, dataset, and then prints or exports the report. I created a separate form to preview the report. When I pass the report object to the preview form, I receive “Invalid Report Source.” The report prints and exports just fine, I just cannot preview the report. I do not want to duplicate the code in the preview form, I was hoping that I could just pass the report object. Snippets of my code are below. Any suggestions?

public static class CrystalReportUtilities
{
    private static ReportDocument goReport {get; set;}
    private static string gsReportName { get; set; }
    private static string gsSqlString { get; set; }
    private static object[,] goParameters { get; set; }

    public static void generateReport(parameters...)
    {
      goReport = loadReport();
...
      goReport.SetDataSource(DataTable);
...
      previewReport();


    private static void previewReport()
    {
        CrystalReportPrintPreviewForm loReportPreview = new CrystalReportPrintPreviewForm(goReport);
        loReportPreview.ShowDialog();
    }


public partial class CrystalReportPrintPreviewForm : Form
{
    private ReportDocument goReport;

    public CrystalReportPrintPreviewForm(ReportDocument poReport)
    {
        InitializeComponent();

        goReport = poReport;
    }

    private void crystalReportViewer1_Load(object sender, EventArgs e)
    {
        try
        {
            if (goReport != null)
            {
                crystalReportViewer1.ReportSource = goReport;  // Receive "Invalid Report Source"
            }
        }

Problem resolved. I am running on a Windows 7, 64 bit OS. I originally installed Crystal Reports for 64 bit Visual Studio 2010. It appears that you need both, the 64 bit and 32 bit version of the runtimes, with SP4.
