Hi guys,

I just migrated my C# WinForms application from VS2015 Professional to VS2019 Professional. Now when I run my Crystal Report (version SP26), a dialog box pops up informing that "The parameter is incorrect." My report worked perfectly on VS2015 and CrystalReports SP25.

Any ideas on what could be causing this error? Thanks a lot for your time and help. I really appreciate it!

Best regards,

JC :)

What I have tried:

Here's my code for the Form that contains the ReportViewer:

using CrystalDecisions.Shared;
using System;
using System.Windows.Forms;

namespace Bremington
{
    public partial class AniversariantesRV : Form
    {
        public AniversariantesRV()
        {
            InitializeComponent();
        }
        private void CrystalReportViewer1_Load(object sender, EventArgs e)
        {
            setReportParameters();
        }

        private void setReportParameters()
        {
            ParameterFields paramFields = new ParameterFields();

            ParameterField pfMes = new ParameterField();
            ParameterField pfUnidade = new ParameterField();

            pfMes.ParameterFieldName = "prmMes";
            pfUnidade.ParameterFieldName = "prmUnidade";

            ParameterDiscreteValue dvMes = new ParameterDiscreteValue();
            ParameterDiscreteValue dvUnidade = new ParameterDiscreteValue();

            dvMes.Value = Aniversariantes.varMes;
            dvUnidade.Value = Aniversariantes.varUnidade;

            pfMes.CurrentValues.Add(dvMes);
            pfUnidade.CurrentValues.Add(dvUnidade);

            paramFields.Add(pfMes);
            paramFields.Add(pfUnidade);

            crystalReportViewer1.ParameterFieldInfo = paramFields;
        }
    }
}

Go back to VS15 and try again. Need to learn about "different realities".

It seems the good people at CodeProject are getting a bit tired of all the Crystal Report problems. So if no one answers your question take a look at an alternative like FastReport, see: open-source-reporting-tools[^]

Hi, Rick. It was a Windows 10 issue. The problem was fixed after a brand new install.
Thanks for replying!
