Export to PDF throws a System.Overflow exception
Hi all,
I'm using VS2002, with VB.NET
I have a problem when trying to export a report to PDF. Let's see following code:
' 1. LoadReport
Report.Load(RutaTemporal)
' Set connection string
Report.Dictionary.Connections(0).ConnectionString = DAL.CnSQL
DSCabecera = Report.GetDataSource("TblCabecera")
DSDetalle = Report.GetDataSource("TblDetalle")
DSCabecera.Enabled = True
DSDetalle.Enabled = True
Report.Prepare()
Dim export As FastReport.Export.Pdf.PDFExport = New FastReport.Export.Pdf.PDFExport()
Dim ResultFile As MemoryStream = New MemoryStream()
Report.ShowPrepared() --> Just to check the report works; in the final version will be removed
Report.Export(export, ResultFile) --> Crashes
The report is shown perfectly when "ShowPrepared". But Export sentence crashes with message "System.Overflow".
Can someone help me?

Hi,
I've found the reason. In one of the Datasets used in report, in one row there were some columns with NULL values, alghought that columns weren't shown in the report.
I've modified the DataSet to prevent NULL values, and the error has dissapeared
