Issues GroupDocs.Viewer for .Net- Version 2.2

  1. Issue: Possible Encoding Problem? I have *.msg Files that every line containing a special-character is truncated



    2. Issue: Performance Problem? I have *.eml Files with a size of 9KB. The Viewer need 20 sec. to display. Server ist not overloaded and has enough Memory (128GB). Sometimes leads to Issue 3



    3. Issue: Random exceptions: [DirectoryNotFoundException: Ein Teil des Pfades “C:\inetpub\wwwroot\HiperCom2014\Web\Temp\temp\Cache\f9cb3535-aff8-47f5-8aff-54ff4748d5a3.eml” konnte nicht gefunden werden.]

Hi,


I’m sorry to hear that you have such issues. You use a very old version of the Viewer library - please migrate to the latest Viewer if possible. If you can’t migrate to the Viewer 3.0 for various reasons please at least update your library up to 2.19 version.

If you will have any issues or need help with migration - please create a new forum thread and mark it with 3.0 in the subject.

Best regards.

Thank for your post.

This is what is guessed…



2 questions:

- We have Version 2.2 is it a downgrade to 2.19?

- Costs for a 1 year subscription to Version 3.0



Best regards

Hi Iganz,


Sorry but could you please specify a full version of the library that you use is it 2.2.0?
Price information you can find here.

Best regards.

Hi Pavel



Yes, it’s 2.2.0



Regards

Hi again,


Thank you. In such case your version is a seventeen versions behind of the 2.19 version.

Best regards.

Ok, i see. Thank you.



Am I entitled to upgrade to 2.19?



Regards

Ignaz

Hi Ignaz,


Yes, you can update your library up to 2.19.0 version, but since we have released a 3.0 version which have nothing with the 2.x version - its totally rebuilded and reconfigured the 2.x versions will not be released any more. Since that the best way is to migrate to the 3.0 version. For how to migrate you check our documentation .

Also could you please share with me example of your files with which you have these issues.

Best regards.

Hi Pavel



Thank you for your help.

I want first try to upgrade to 2.19 since it seems to me the least effort.



Is there a way to provide me this Version?



Best regards

Ignaz

Hi Ignaz,


Sure, you can download it here

Best regards.

Hi Pavel



Thank. you. I’ll try it and then give feedback.



Regards

Ignaz

Hi Ignaz,


I will wait for your feedback.

Thank you.

Hi Pavel



It looks more or less like the same.

Besides there is warning showing of an Evaluation Version.

I will do some more testing and get back to you with more detailed feedbacks.



Regards

Ignaz

Hi Ignaz,


Thank you for the information. Please share with me your code and files examples that I can reproduce the issue on my side.

Also make sure that in the run time your application uses the new version of the library - you can check it with such code line:
<%= typeof(Groupdocs.Web.UI.Viewer).Assembly.GetName().Version.ToString() %>

if the version will not be a 2.19 then clean the cache and rebuild the application.

Best regards.

Hi Pavel



The Version showed is: 2.19.0.10089

It works most of the time but I still got random exceptions:

Hi Pavel



The code is simple. I attached it.



Regards

Ignaz

Hi Ignaz,


Thank you for this information. Could you please share with me example of your code and files that you try to view when you get this error.

Thank you.

Hi again,


Thank you for the example code. Could you please also share with me code of the Viewer initialization, if possible you can share example project which I can run and debug on my side and help you to resolve the issue.

Thank you.

Hi Pavel



The init is done in the Global.asax:





Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)

’ Wird beim Start der Anwendung ausgelöst

Viewer.EnableFileListRequestHandling(True)

Viewer.SetLicensePath(Server.MapPath("~" & cConfiguration.GetBaseUrl() & “GroupDocs.Viewer.for.NET.lic”))

End Sub





Regards

Ignaz

Hi again,


In the initialize code you have missed SetRootStoragePasth. Please use this example:

Viewer.SetRootStoragePath(<path to the directory where you will store your documents and the Viewer’s image cache>);

Best regards.
