Document doc = new Document(“C:/Projects/FileUpload/Temp/0a682f2a-3449-4c51-a493-3ef38d251d6c.html”, new HtmlLoadOptions());

doc.Save(@“c:\temp\test4.pdf”);

The problem seems to be related with the regional setting of the system

When decimal symbol becomes ‘,’ instead of ‘.’ or digit grouping symbol ‘.’ of ‘,’ the aspose pdf lib throw an useless empty error!

See No conversion defined 1,2.

This can’t be right?

Hi Andy,

Thanks for using our API’s.

I have tested the scenario using Aspose.Pdf for .NET 11.7.0 in Visual Studio 2010 project with .NET Framework 4.0 running over Windows 7 (x64) with Regional Settings as English (United States) and I am unable to notice any issue. Can you please share some details regarding your working environment i.e. Operating Systems detail, Regional Language settings etc, so that we can again try replicating the issue in our environment.

We are sorry for this inconvenience.

[C#]

HtmlLoadOptions htmlLoadOptions = new HtmlLoadOptions();
htmlLoadOptions.PageInfo.Margin.Bottom = 10;
htmlLoadOptions.PageInfo.Margin.Top = 20;
//see html file in solution
Document doc = new Document(@"C:\0a682f2a-3449-4c51-a493-3ef38d251d6c.html", new HtmlLoadOptions());
doc.Save(@“C:\0a682f2a-3449-4c51-a493-3ef38d251d6c.pdf”);

Hi,
I've tested with version 11.7.0 and had the same problem.
Just goto regional settings, set format to english (united states), goto additional.

Switch Decimal symbol from . -> ,
Switch Digit grouping symbol from , -> .

Save settings and try running code above.
Save.

My operating system:
Windows 10, .Net framework 4.5

Hi Andy,


Thanks for sharing the details.

I have tested the scenario using Aspose.Pdf for .NET 11.7. 0 in VisualStudio 2015 project with .NET Framework 4.5 running over Windows 10 (x64) and I am unable to notice any issue. Before performing the conversion, I have set regional language settings and custom formatting as per your earlier shared image but still I am unable to reproduce it. If possible, please share some sample project, so that we can again try replicating the issue in our environment. We are sorry for this inconvenience.

That’s strange, we’ve tested the same scenario on some different pc’s (same setup windows 10 and 7, 64 bit) and after the regional setting additional change, they all encounterd the same problem. Just switch decimal symbol from ‘dot’ to ‘comma’ and digit grouping symbol from comma to ‘dot’.


Thx
