Hi,
We are having trouble to load stream (xlsx file) whith the spire lib´s

I have a code below
Code: Select all
      byte[] _file = System.IO.File.ReadAllBytes(@"D:\document.xlsx");
                Workbook workbook = new Workbook();
                workbook.LoadFromStream(new MemoryStream(_file));       // freezes here!

                WorksheetsCollection sheets = workbook.Worksheets;


The file (document.xlsx) is inside attach document.rar
A thread stays in method "workbook.LoadFromStream" forever, not throw any exception.

Hello,

Thanks for your post. After an initial test with the most new version(Spire.XLS Pack Hotfix Version:7.12.125), I was unable to reproduce the issue. Please update to this version and try again.

Best regards,

Simon,

Thanks for your repply. Sorry for my mistake but with this hotfix all works fine when I´m working with XLSX documents but my solution also works with DOCX e PPTX documents.
So when I used this hotfix over the last version of Spire.Office for .NET (Version:2.16.23)
I have a problem with PPTX when I try to instance Presentation object like this:

Code: Select all
Spire.Presentation.Presentation presentation = new Spire.Presentation.Presentation();


Below are the exception message:
Não foi possível carregar arquivo ou assembly 'Spire.Pdf, Version=3.9.480.14040, Culture=neutral, PublicKeyToken=663f351905198cb3' ou uma de suas dependências.A definição do manifesto do assembly localizado não corresponde à referência do assembly. (Exceção de HRESULT: 0x80131040)

I think Spire.Pdf (Spire.Office for .NET - Version:2.16.23) and Spire.Xml (your hotfix version) needs a diferent version for Spire.Pdf

Hello,

Thanks for your feedback. The Spire.XLS.dll v7.12.125 has not been merged into Spire.Office 2.16.23, that is why you will encounter the compatibility issue. The next version of Spire.Office will include the fix. Once it's available, we will let you know.

Best regards,
Simon

Simon,

Thanks for your answer, do you have a version from Spire.Presentation.dll that is compatibly with dependencies from Spire.Excel.dll new release (.125)? I´m processing a huge volume of documents and the current error with Spire.Excel.dll is crashing my application and so I can´t do anything to work around to avoid this (the crash are finalizing my application) and que processing queue is growing.

Thanks,

Alioth Latour

Simon,

Now I have the same freezing problem with another XLSX document.

Follows the file where the problem occurs.

The freeze problem occur when I tested this call in a application made specificaly to reproduce the problem (a little windows forms application), on another test with the same xlsx file in complete code of my program, using a multi thread setup, the LoadFromStream function doens´t freeze but after your return I get a crash in my application caused by Spire (I think that this occur in a background thread used internaly by Spire, because I can´t catch this exception with a normal try/catch or with a global exception manner).
