the error is " a window handle is not created for the control"

My code is :


using System;
using System.IO;
using System.Data;
using System.Text;
using System.Drawing. Imaging;
using System.Drawing. Printing;
using System.Collecti ons.Generic;
using System.Windows. Forms;
using Microsoft.Repor ting.WinForms;

public class Demo : IDisposable
{
private int m_currentPageIn dex;
private IList<Stream> m_streams;

private DataTable LoadSalesData()
{
// Create a new DataSet and read sales data file
// data.xml into the first DataTable.
DataSet dataSet = new DataSet();
dataSet.ReadXml (@"..\..\data.x ml");
return dataSet.Tables[0];
}
// Routine to provide to the report renderer, in order to
// save an image for each page of the report.
private Stream CreateStream(st ring name,
string fileNameExtensi on, Encoding encoding,
string mimeType, bool willSeek)
{
Stream stream = new FileStream(@".. \..\" + name +
"." + fileNameExtensi on, FileMode.Create );
m_streams.Add(s tream);
return stream;
}
// Export the given report as an EMF (Enhanced Metafile) file.
private void Export(LocalRep ort report)
{
string deviceInfo =
"<DeviceInf o>" +
" <OutputFormat>E MF</OutputFormat>" +
" <PageWidth>8.5i n</PageWidth>" +

" <MarginRight>0. 25in</MarginRight>" +
" <MarginBottom>0 .25in</MarginBottom>" +
"</DeviceInfo>";
Warning[] warnings;
m_streams = new List<Stream>();
report.Render(" Image", deviceInfo, CreateStream, out warnings); foreach (Stream stream in m_streams)
stream.Position = 0;
}
// Handler for PrintPageEvents
private void PrintPage(objec t sender, PrintPageEventA rgs ev)
{
Metafile pageImage = new
Metafile(m_stre ams[m_currentPageIn dex]);
ev.Graphics.Dra wImage(pageImag e, ev.PageBounds);
m_currentPageIn dex++;
ev.HasMorePages = (m_currentPageI ndex < m_streams.Count );
}

private void Print()
{
const string printerName =
"Microsoft Office Document Image Writer";
if (m_streams == null || m_streams.Count == 0)
return;
PrintDocument printDoc = new PrintDocument() ;
printDoc.Printe rSettings.Print erName = printerName;
if (!printDoc.Prin terSettings.IsV alid)
{
string msg = String.Format(
"Can't find printer \"{0}\".", printerName);
MessageBox.Show (msg, "Print Error");
return;
}
printDoc.PrintP age += new PrintPageEventH andler(PrintPag e);
printDoc.Print( );
}
// Create a local report for Report.rdlc, load the data,
// export the report to an .emf file, and print it.
private void Run()
{
LocalReport report = new LocalReport();
report.ReportPa th = @"..\..\Report. rdlc";
report.DataSour ces.Add(
new ReportDataSourc e("Sales", LoadSalesData() ));
Export(report);
m_currentPageIn dex = 0;
Print();
}

public void Dispose()
{
if (m_streams != null)

m_streams = null;
}
}

}
