Hi,

I am trying to create a word document  and then save it to pdf using the code below.  finalOuput is a string in wordml format.  This all works fine.  I have been trying to deploy to Microsoft Azure.  On this platform the wordDocument.PageCount returns an OutOfMemoryException as does wordDocument.SaveToPdf().  Is there anything in these properties/methods that needs access to the file system or require some form of special permissions?  Do you know of anything that would be causing them to throw this exception.

MemoryStream openStream = new MemoryStream(Encoding.UTF8.GetBytes(finalOutput));
Document wordDocument = new Document(openStream, null, loadFormat, null);
              
MemoryStream pdfStream = new MemoryStream();
wordDocument.SaveToPdf(0, wordDocument.PageCount, pdfStream, new Aspose.Words.Rendering.PdfOptions());

Best regards

David

Hi Alexey,

 

I was speaking to you today about a memory exception I was getting while trying to run aspose.words on windows azure.  I’ve created a very simple page that has the following code on the page_load.  I created a simple docx that has one line of text.  When I run the following i get the error below.  I thought i’d send this to you to see if it gives you any clues as to why it might be throwing the error.

 

Document doc = new Document(Server.MapPath("in.docx"));

Response.Write("page count: " + doc.PageCount);

 

 

System.OutOfMemoryException was unhandled by user code

Hi,

I was wondering if there was any more information about this issue as it is holding us up from using ASPOSE on projects even though we have bought a full license.

I have posted the same issue on the Windows Azure forums and got this answer.

"We feel it may be due to continuously memory being consumed up during access of the link. This can be fixed by disposing the Graphics object instance used in the code. Can you please give a try doing this and confirm us if this really helps?"

I don't know if this is any help but thought i'd get back to you with it anyway.

If you could let me know of any changes to the status of this defect.

Best regards
David

Hi David,

 

Thank you for additional information. Unfortunately, the issue is still unresolved.

Yesterday we have released new version of Aspsoe.Words. Did you try it? You can download Aspose.Words 6.4.0 from here:

 http://www.aspose.com/community/files/51/file-format-components/aspose.words-for-.net-and-java/entry180062.aspx

 

Best regards.

Hi Alexey,

I have just tried the latest version of Aspose.Words and it still doesnt work.  It throws exactly the same exception.  Do you have any idea of timescales on when this might be looked at as it's quite urgent for us.

Best regards
David

Hi David,

 

Thanks for your request. Unfortunately, I cannot provide you any estimate regarding this issue at the moment.

 

Best regards.

Hello,

I tried today to use Aspose.Words in my (migrated) Azure-application, but I've got also this Memory Exception by executing the Save-method (in System.drawing.graphics).

Please help!

Hello!

 

Thank you for reporting this.

 

Please be more specific in what action produced the exception. Are you also saving the document in PDF format? Please attach the source document and show the code fragment that manipulates the document using Aspose.Words.

 

Regards,

Thank you for the fast reply.

I made a testproject with one webform and one button.

By pressing this button, the next commands will be executed:

Document theDoc = new Document();
theDoc.Save("Test.pdf", SaveFormat.Pdf, SaveType.OpenInBrowser, Response);

The error is fired in line 2.

I've attachted the whole project.

 

Kind regards,

Marcel

Hello Marcel!

 

Wow, I’m working with Visual Studio 2005. Not a problem – already have recreated the project and got it run J

 

I cannot reproduce this on Windows XP. Let’s assume here’s really the same issue that David reported at the top of the thread. Would you please try calling Document.PageCount to ensure? I have no Windows Azure within easy reach. Document.PageCount should produce the exception even when called on an empty document. If you reproduce, please also post the stack trace here.

 

Thank you in advance.

I'm working with VS2008 with the Azure Toolkit July 2009 CTP.

When I run this project as an usual web-application, it runs good.
When I run this as an Azure application, the error comes up.

So, the only manner to raise this exception is to run this project as an Azure-application within VS 2008


Regards,
Marcel

Thank you. This is the same error. We’ll notify you when it is fixed.

To all who have problems with Aspose.Words on Azure:

1. Do you use the "Windows Azure" part of the Azure Services Platform?
2. Do you actually upload your application to Windows Azure and it fails there, in the cloud?
3. Do you need to register and get an invitation from Microsoft to use Windows Azure?

I register and apply for invitiation several times but I have never received one. Maybe someone can temporarily give me access to their Windows Azure account so I can try upload an application with Aspose.Words there and fix it once and for all.

You can send me a private message using this forum to contact me.
