Error while trying to convert .doc file to PDF/A-1b

Aspose.Words Product Family

Hi,

I'm facing a problem while trying to convert a MSWord .doc file to a PDF/A-1b using Aspose.Words.

I use this code:

Document doc = new Document(this.m_inputWordFileName);
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.Compliance = PdfCompliance.PdfA1b;
doc.Save(this.m_outputPdfFileName, pdfSaveOptions);

The framework gaves me the error (in french) "La référence d'objet n'est pas définie à une instance d'un objet", meaning null reference exception in english, with this stacktrace:

I'm currently using version 10.1.1.0 but I also tried latest version (11.1.0) and the problem still remains. I use the .net 3.5 client profile dlls and encountered this error on only one .doc file, all the others are correctly converted.

Hi Bertrand,


Thank you for inquiry. I am afraid, I could not reproduce this problem on my side. Could you please create a simple console application which reproduces the issue on your side and attach it here? We will take a closer look into what’s happening and provide you with some further feedback. I have attached output PDF file for your reference.

We'll investigate the issue at our end and guide you accordingly.

Hi Imran,

Please find here a zip archive containing a VS console project and the corresponding compiled binaries.

The error still occurs with this very simple code, using this .doc file.

Hi Bertrand,


Thanks for your inquiry. We tested your document on our environment and all works fine. We used windows server 2003, windows 7. It appears that your application is having a problem on your test environment. Please try it on another computer and tell me how you go.

Hi Bertrand,


Thanks for your inquiry. With Aspose.Words v11.1.0, I was unable to reproduce this exception on my side either. Could you please try rendering the Word document, you’re getting this exception with, to PDF on a different machine and let us know your findings (e.g. details about the development environment on that machine etc).

Thank you for your cooperation.

Hi Awais, Imran,

You were right, I managed to render the pdf correctly with the last version of the DLL. I think I made a mistake when trying to use it yesterday.

Everything works fine now, sorry for this waste of time, and thanks a lot for your great support !

Regards,

Bertrand
