Suppress Exporting Crystal Report as PDF IF No Data

Hello,

I batch export several Crystal Reports as PDF using a VB.NET 2003 Windows application.  However, since I am exporting to PDF and not printing, I cannot suppress if there are no records anymore.  The property the report has to suppress printing if no data doesn't apply to exporting as PDF.  Therefore,  I end up with several PDFs that are blank because they did not have any records.

I'm using the ReportDocument (CR)  class and the CR.ExportOptions process to export.  Here's a sample of what I do after the report is ready to be exported.

Dim CR as New  ReportDocument
..
..' provide path to open the report and enter parameters here too.

With CrExportOptions
        ' Set the destination to a disk file
      .ExportDestinationType = ExportDestinationType.DiskFile
      ' Set the format to PDF
      .ExportFormatType = ExportFormatType.PortableDocFormat
      ' Set the destination options to DiskFileDestinationOptions object
      .DestinationOptions = CrDiskFileDestinationOptions
      .FormatOptions = CrFormatTypeOptions
End With
' Export the report to the PDF folder path
CR.Export()

Is there a way to stop the exporting process if the report is blank or has no records?   I was hoping to use something like size property, but I can't find it.

Any help would be tremendously appreciate it.
