Value can not be null Parameter name: image, Azure RichText

[Hélio]

hello, I'm using Stimulsoft report published in azure,

I have a problem when using a report containing the RichText component to load the same error happens:

[ArgumentNullException: Value can not be null.
Parameter name: image] System.Drawing.Graphics.DrawImage ..

Erro.png (82.71 KiB) Viewed 2388 times

report Error.png (41.11 KiB) Viewed 2388 times

I wonder if anyone can help, it looks like a bug in the report engine.

Is there any minimum requirement so you can use richtext in azure?

thank you

Hello.

Please, try to run next code:

Code: Select all

            rep.Load(...);
            rep.Render(false);
            try
            {
                MemoryStream ms = new MemoryStream();
                rep.ExportDocument(StiExportFormat.HtmlTable, ms);
            }
            catch
            {
                StiReport rep2 = rep.CompiledReport != null ? rep.CompiledReport : rep;
                //check rep2.ReportRenderingMessages
            }

Inside the catch check the ReportRenderingMessages and send them to us.

Thank you.

Hello, the problem continues, the value of report.ReportRenderingMessages property is null. In the execution after the Render(false) or in the catch block.

Thank you

Hello.

If we right understand you issue, the report works before publishing it on Azure, then it don't work.
We have made some changes in the code from our previous post. Please, check the ReportRenderingMessages.

If there is still null, could you send us a sample project for analysis.

Thank you.

Hello, I made the change as it was past and the ReportRenderingMessages property is with the following error:

RichText1 A generic error occurred in GDI +


thank you

Hello.

Sorry, but we couldn't build your project. There are missed assemblies.
Could you send us more simple project which reproduces the issue?

Thank you.

Hi, I'm sending a new project with my problem.

To run it, you must re-add the reference to these three dll:

Stimulsoft.Base.dll
Stimulsoft.Report.dll
Stimulsoft.Report.Mvc.dll

And must also recompile all solution, so that the nuget restore the project packages.

Now just run the site.

Recalling that the error only happens published in Azure.

Hello, Helio.

We use Metafile to draw RichText. Unfortunately, it's impossible to create Metafile on Azure Websites because it runs not in Full Trust environment.

Unfortunately it's impossible to use RichText components in your project.
To avoid such error you should set the StiOptions.Engine.FullTrust option to false.

Thank you.
