C# program keep on running despite no error

Am working in a project where i should give a crystal reports RPT file as
input and get the properties of that report.
But am facing a problem in loading the report itself so i have used
isLoaded() function to check whether the report is loaded or not.
I have used the following code.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Web;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
namespace sampleretreival
{
public partial class Form1 : Form
{
public string flName;
public Form1()
{
InitializeComponent();
Retrieve.Enabled = false;
}
private void listBox1_SelectedIndexChanged(object sender,
EventArgs e)
{
if (lstFiles.SelectedItems.Count > 0)
{
Retrieve.Enabled = true;
}
else
{
Retrieve.Enabled = false;
}
}
private void Browse_Click(object sender, EventArgs e)
{
openFileDialog1 = new OpenFileDialog();
openFileDialog1.Multiselect = false;
openFileDialog1.Filter = "Crystal Report Files | *.rpt";
openFileDialog1.ShowDialog();
flName = openFileDialog1.FileName;
if (flName.Length != 0)
{
lstFiles.Items.Insert(0, flName);
Retrieve.Enabled = true;
}
else
{
MessageBox.Show("Please select the crystal report files
for analysis.", "SAMPLE", MessageBoxButtons.OK,
MessageBoxIcon.Information);
Browse.Focus();
}
}
private void Retrieve_Click(object sender, EventArgs e)
{
int a=1;
ReportDocument rpt = new ReportDocument();
rpt.Load(flName);
int count = 5;
if (rpt.IsLoaded)
{
MessageBox.Show(count.ToString());
}
else
{
MessageBox.Show(a.ToString());
}
}
}
}
After compiling I clicked the Browse button to select the report from the
disk. But when I click Retrieve button,program keep on running. Am not
getting any output or any error.
