Unable to pass a int Parameter to a Crystal Report

Question

I have a simple Crystal Report with a single parameter, which should produce a single item on the report. I have listed the code below, as well as the Parameter settings in the report. When I try to print the report to the printer (The final line in the code snippet), I receive the following Exception;

CrystalDecisions.CrystalReports.Engine.ParameterFieldCurrentValueException was unhandled Message=Missing parameter values.

I have also tried the report using the ParameterFieldDefinitions and ParameterFieldDefinition objects, but I end up with the same results.

Any help would be greatly appreciated.

        ReportDocument loReport = new ReportDocument();

        loReport.Load(path+"InventoryItemsBarCodeLabel.rpt");

        SqlConnectionStringBuilder loConnectionString = new SqlConnectionStringBuilder(ConnectionUtilities.getConnectionString());

        ParameterValues currentParameterValues = new ParameterValues();
        ParameterDiscreteValue parameterDiscreteValue = new ParameterDiscreteValue();
        parameterDiscreteValue.Value = Convert.ToInt32(psMasterId);

        loReport.SetParameterValue("pnMasterId", parameterDiscreteValue.Value);
        loReport.SetDatabaseLogon(loConnectionString.UserID,
            loConnectionString.Password,
            loConnectionString.DataSource,
            loConnectionString.InitialCatalog);
        loReport.Refresh();
        loReport.PrintToPrinter(1, false, 1, 1);

Report Parameter: Name: pmMasterId, Type: Number, List of Values: Dynamic, Value = MasterId, Description = MasterId, Parameters = ?pnMasterId

Report Selection Record: {Inventory_Items.MasterId} = {?pnMasterId}

Answer 1

try to move SetDatabaseLogon() method before setting parameters; I believe it resets report document and any params previously passed.
