Spire.doc Word to HTML

[svendelboe]

Hi, I get a strange error during converting to HTML

using (MemoryStream memoryStream = new MemoryStream())
{
using (MemoryStream outStream = new MemoryStream())
{
memoryStream.Write(templateContent, 0, templateContent.Length);
Document document = new Document();
document.HtmlExportOptions.ImageEmbedded = false;
document.LoadFromStream(memoryStream, FileFormat.Docx);
document.SaveToStream(outStream, FileFormat.Html); <----Line throw error
}
}

System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+.
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
at spr⍰.ᜀ(Image A_0, String A_1, Int32 A_2, Int32 A_3, Boolean A_4, ImageFormat A_5)

Hello,

Thanks for your inquiry. After an initial test, I was unable to reproduce the issue on my side. To help us investigate further, please share us with your Word file? You could attach it here or send to support@e-iceblue.com.

I have 2 MVC applications which run on the same IIS server. One application has no problems with this code, where another one has. Both applications reading the same word document. When I am reading error I can se that it happends her
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
It look like spire.doc tries to save something to the fysical location, because method takes as parameter filename. So it could be problem with service user rights? Where does spire.doc saves data?

Hello,

Please tell us if the two applications will both save the Word document to Html stream and one of them has no problem.

One of my application is for testing and another for production. They both works with the same data, but each application runs under own user. Documents are the same and are at the same location. Application should load the word document from drive convet it to html and show in a view to user. So they both loading it to memorystream. Basicly to be sure I copied whole test folder to production, so the code is 100% the same. But the error comes only in production and no problem in test.

Hello,

Sorry for the late reply. Actually, the images in the document will be saved under a relative path while setting ImageEmbedded = false, it seems that the path is not correct or you don't have the write permission under the path. Please set the saving path of the images and try again.

Code: Select all

                    Document document = new Document();
                    document.LoadFromStream(memoryStream, FileFormat.Docx);
                    document.HtmlExportOptions.ImageEmbedded = false;
                    document.HtmlExportOptions.ImagesPath = @"C:\";
                    document.SaveToStream(outStream, FileFormat.Html);
