SpireDocs hanging

[jblair@catic.com]

Hi,

We are using SpireDocs in an ASP.net application working with Word based documents, stored as byte arrays. If the document contains either a footnote or endnote, it causes the following code to hang:

pConvert.LoadFromStream(New MemoryStream(pFileDocument.FileData), Spire.Doc.FileFormat.Docx2013)

pConvert is of type Document.

Obviously in the environment we are deployed to (IIS website), we cannot have the application pool hung, spiking the CPU. It makes the entire machine unusable for other services and websites hosted by it.

We are running SpireDocs v6.0.52.4040

Please help!
Thx,
Jay

Thank-you for your response Jane. I have sent a very simple document that causes the problem to the email address you mentioned.

I look forward to hearing from you!

Hello Jay,

Thanks for your email.
Sorry I didn’t reproduce the issue on my side. Please make sure the byte data you fetched from the database is correct.
You could use the code

Code: Select all

System.IO.File.WriteAllBytes(@"c:\test.docx", pFileDocument.FileData);

to have a check.
If the issue still exists, please write back and give more detail on the project environment.

Hi Jane,
I have sent you a zip file containing a Visual Studio 2017 solution. It is just a console app that imports Spire.doc from nuget, and has 6 lines of code. It also contains the test.docx file, which I wrote from our ASP.Net application as you requested.

That test.docx looks fine in Word 2016. It has the endnote that is causing the problem.

All this project does is ready test.docx, and then call Document.LoadFromStream. It then hangs.

I figured if we could reproduce it in as simple an environment as possible that would make things much easier.

One thing I noticed:

If I replace the endnote in the doc with a footnote, or a new endnote, it works in this simple application (not the full ASP.Net application)

However, since this is a web based application meant to be used by any number of people, I cannot have it hanging and bringing down my entire web host.

What I really need is for spire.doc not to hang. Even if it throws an error, that is a much better scenario that we can handle.

Please let me know if you need anything else from me.
Thx,
Jay

Thanks for the update Jane.

Do you have any idea when this might be fixed?

We were hoping to go live with our web application this month, but I cannot with this issue.

Depending on when it might be fixed, we will need to decide if we have to pull Spire.docs out of the application and move in a different direction.

Any information would be greatly appreciated.
Thank-you!
Jay

Hi Jane,

Thx,

Excellent, again, thank-you!

Hello,

Glad to inform that your issue has been resolved and the hotfix (Spire.Doc Pack(hot fix) Version:6.0.77) is available now. Kindly note when writing the bytes, you need to use mem.ToArray() to get all the data rather than GetBuffer() for only the data in buffer area.

Code: Select all

string outputFile = @"output.pdf";
string inputFile = @"input.docx";
var bytes = System.IO.File.ReadAllBytes(inputFile);
var doc = new Document();
var mem = new MemoryStream();
doc.LoadFromStream(new MemoryStream(bytes), FileFormat.Docx2013);
doc.SaveToStream(mem, Spire.Doc.FileFormat.PDF);
File.WriteAllBytes(outputFile, mem.ToArray());
doc.Close();
