Error creating window handle

Hi,

My service fetching data from sqlserver database and create pdf using report viewer and then save that pdf on ftp server. I am not using any window form.

Steps:
1) craeting report viewer object in method like ReportViewer rptViewer = new ReportViewer();
2) Fetching data from database and fill dataset.
3) Set all report viewer properties.
4) Create ftp request.
5) write report viewer bytes data on the ftp server using ftp stream.
6) rptViewer.LocalReport.Refresh(); rptViewer.RefreshReport();
7) Clear and Dispose dataset object.
8) clear and Dispose report viewer object

After that same process for next record.

Thanks
