thread aborted error on save

[Bert Sirkin]

I'm starting with a Word template and populating it with data. I am then saving the files to the temp folder, and opening it in the browser. I really don't need to save a physical file, but can't seem to send a stream to the browser.

I create the word document with this:

     Dim document As New WordDocument("c:\mypath\myfile.dotx")

after populating the document with data, I execute this line (per https://help.syncfusion.com/file-formats/docio/loading-and-saving-document?cs-save-lang=1&cs-lang=vb ):

     document.Save("c:\mypath\myNewFileName.docx", FormatType.Docx, response, HttpContentDisposition.InBrowser)

and get a thread-aborted error. 

How can I stream the document to the client browser without creating a thread-aborted error?

Using the code below, I run into 2 major issues (although a document is sent to the browser):

1) When the "document.Save" is called, it generates a runtime error (thread aborted); and

2) If I trap the error and ignore it, I get a prompt to open the document. If I try to open it, I get a dialog indicating: "We're sorry. We can't open Sample.docx because we found a problem with its contents. The file is corrupt and can't be opened.". 

If I click OK, I get another dialog indicating: 

If I click "Yes", it opens.

Here is the "hello-world" code:

--------------------------------------------------

Imports Syncfusion.DocIO

Imports Syncfusion.DocIO.DLS

Public Sub CreatDoc()

            Dim sTemplateDoc As String = Server.MapPath("~/Template/TemplateTest.dotx")
            Dim document As WordDocument = New WordDocument(sTemplateDoc, FormatType.Docx)
            document.Save("Sample.docx", FormatType.Docx, HttpContext.Current.Response, HttpContentDisposition.Attachment)
            document.Close()

End Sub

--------------------------------------------------

What do I need to do to avoid the "thread-aborted" and "corrupt file" errors??

It's VERY easy to reproduce. I've attached a complete project - you'll just need to add references to the Syncfusion files (Syncfusion.Docio.Base), as I had to remove them to keep the ZIP file under the 30mb max.

Hi Bert,

Thank you for your update.

We can reproduce the reported thread aborted exception in our end, and we suspect it to be a defect. We will validate this issue and update you with more details on 8^th June 2020.

Please let us know if you have any other questions.

Hi Bert,

Thank you for your patience.

On further checking the reported issue, we have used HttpResponse.End Method in the saving of word document in Asp.Net MVC platform. This method Sends all currently buffered output to the client, stops execution of the page, and raises the EndRequest event. And also, this method tries to raise a ThreadAbortException exception. So, we suggest you to avoid using try and catch statement while save and returing the word document in MVC platform.

Please refer the below link to know more about the same.
https://docs.microsoft.com/en-us/dotnet/api/system.web.httpresponse.end?view=netframework-4.8

Please let us know if you have any other questions.

I'm not sure this applies to me, as I'm not running the Asp.Net MVC platform- my project is am ASP.NET Webforms project.

I eliminated the Try/Catch, but it still generates an error.

[Manikandan Ravichandran]

Hi Bert,

Thank you for your update.

This is applicable or both MVC and WebForms applications which are returns the output to client. After removing the try catch statement form the sample, the exception not received by catch block and directly sent to client browse and its working fine in our end.

Please find the modified sample from below link.

I'am using the last version of syncfusion export Component. I use Asp.Net WebForms and my frameword is 4.72. I use the following call:

FlatGridLotacao.DataSource = dtLotacao;

FlatGridLotacao.DataBind();

exp.Export(FlatGridLotacao.Model, FlatGridLotacao.DataSource, "Relatório Usuários Por Departamento de Lotação.xlsx", ExcelVersion.Excel2010, true, true, "flat-lime");

System.Threading.ThreadAbortException: 'Thread was being aborted.' is the error that I getting.

   em System.Threading.Thread.AbortInternal()

   em System.Threading.Thread.Abort(Object stateInfo)
