How to remove Load Report Failed Error in Crystal Reports version 13.0?

Question

I am developing a simple app using Crystal Report (Version 13.0) and .NET Framework 4.0 as well as VS 2013. What i am doing is that i have a Crystal report viewer on the form which is supposed to show/load my report when button is clicked. My code to load a report is:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
namespace CystalReportsApp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                ReportDocument rpt = new ReportDocument();
                rpt.Load(@"e:<path>\CystalReportsApp\CystalReportsApp\CrystalReport1.rpt");
                crystalReportViewer1.ReportSource = rpt;
                crystalReportViewer1.Refresh();
            }
            catch (Exception ex)
            {

                throw;
            }
        }
    }
}

Problem i am getting is that whenever i click button, an exception occurs saying this:

CrystalDecisions.Shared.CrystalReportsException was unhandled
HResult=-2146232832

Solutions i have tried are:

1. Checked the path again and again.
2. Checking file permissions on the temp folder as well as on the folder where my report resides.
3. Checking stackoverflow for the answer but couldn't find an answer regarding my problem's details.

But all in vein. Can somebody please tell me as what's going behind the scene?

UPDATED Alongside this forum, i had also posted this question at SAP crystal reports' forum for which somebody answered as to just remove @ sign from the path. But as i remove @ sign, "Unrecognized escape sequence" errors come. Please help! Answer by SAP COMMUNITY NETWORK

Answer 1

Try :

Web

 rpt.Load(Server.MapPath("\\CystalReportsApp\\CrystalReport1.rpt"))

Windows

rpt.Load(@"e:\\users\\shahid sultan minhas\\documents\\visual studio 2013\\Projects\\CystalReportsApp\\CystalReportsApp\\CrystalReport1.rpt")

Answer 2

Your problem (like mine) may still be related to the path to the RPT file. In an .aspx Web Form, you might benefit from this syntax:

    <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
        <Report FileName="~/MyCrystalReport.rpt">
        </Report>
    </CR:CrystalReportSource>

By using a relative path, I was able to execute my report files after many hours of trial-and-error.

MySql.Data.MySqlClient.MySqlDataAdapter myAdapter1 = new MySql.Data.MySqlClient.MySqlDataAdapter(ds.Tables[0].Rows[0]["Query"].ToString(), conn);
                    myAdapter1.Fill(myData);
                    WaitSumCrystalReport3 myr = new WaitSumCrystalReport3();
                    myr.SetDataSource(myData);
                    if (myData.Tables[0].Rows.Count > 0)
                        myr.PrintToPrinter(1, true, 1, 10);
                    cmd.CommandText = "Update tbl_print set Status='1' where ID='" + ds.Tables[0].Rows[0]["ID"].ToString() + "'";
                cmd.Connection = conn;
                cmd.ExecuteNonQuery();
//disposing the crystal report object to clear the temp memroy.. otherwise memory is overflow occurs in future
                    myr.Dispose();
//above statement is used to dispose... it will work fine

Answer 7

In my case, I first got an error: Could not load file or assembly 'CrystalDecisions.ReportAppServer.ClientDoc', Version=xxx' . And then I find and add reference to the xxx version of CrystalDecisions.ReportAppServer.ClientDoc.dll , then run the program, a new error Load Report Failed occur.

After asking my colleague, I goto Project > Properties > Build , and uncheck the Prefer 32-bit checkbox , and restore to use the original version I use of CrystalDecisions.ReportAppServer.ClientDoc.dll , then I can successfully generate report.

Besides I have installed 64-bit version of Crystal Reports runtime engine .

For ASP.NET Web Project, goto

 Tools
  -> Options
   -> Projects and Solutions
    -> Web Projects
     -> Check "Use the 64 bit version of IIS Express for web sites and projects"`

Reference: How can I force IIS Express to run in 32 bit mode?
