  Timeout when exporttoStream

  Nov 09, 2012 02:17 PM|LINK

  hi,

  Can anyone help me with this ?

  I have a webservice calling the .rpt crystal report

  _Result.StatementReport = (MemoryStream)document.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
                                      _Result.ReturnCode = 0;

  
  I need to transform it in stream to be able to get it in my client then export it to pdf.

  but When I to the ExportToStream I get this error

  System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Timeouts are not supported on this stream.
