Error code -2147190908 when exporting to a PDF document with barcode fonts

Hi,

I have a problem in a VB6 program when exporting a report to a PDF file.

The program uses the craxddrt.dll version 11.0.0.2220.

It exports the report like this:

crReport.ExportOptions.FormatType = crEFTPortableDocFormat

crReport.ExportOptions.DestinationType = crEDTDiskFile

crReport.ExportOptions.PDFExportAllPages = True

crReport.ExportOptions.DiskFileName = App.Path & "\" & strVon & ".pdf"

crReport.Export False

The Export function returns the error code -2147190908.

The report contains the barcode font IDAutomationHC39M and I think this causes the problem. Because when I remove the barcode field from the report the export works fine.

I did a little research but there are many reasons that cause the error code. The best hit is the following thread but it contains no satisfying answer.

Does anyone know if there are problems with fonts when exporting to a PDF file?
And if so, is there a solution?

Thanks and best regards
