Best Answer

Note: The (SSRS Font Encoder) has been released since this issue was resolved that offers an easier method of generating barcodes in SSRS without the assembly, config file edits or other components.


You may definitely use the C# code and bundle it in your application and current dll as you have a Developer License.

Dear Ben

I saw this folder after the setup

My license is Code 128 Font Advantage Package

For this case, Can I use bundle Encoding Code128Auto in my CustomAssembly (My custom Assembly is C# and Can run fine without error) is Illegal or not?

Output encoding is the same as .NETAsemmbly Encode (Code.clsIDAutomationBarcode.Code128) or not.

Unfortunately, I am not sure what is going wrong. The config files look okay. You may want to consider streaming the Code 128 barcode using the ASPX Barcode Generator instead of using the font and encoder. At this time, I cannot test or duplicate the setup.

Dear Ben

I sent an email.

BI Report Project comes with VS2013 Shell integrated

Web App, Create in VS2015 (Copy RDL from report project to put inside WebApp Project)

This is not a solution that we can directly support. However, send your RSPreviewPolicy.config to us: Contact Us and we can look at the file.

I created by Business Intelligence Report Project
extension file is .RDL with barcode fonts Code128Auto and the .NET Assembly
but I use to render it by localReport.Render like RDLC (Run Without Report Service Server and deploy to Web Server not install Report Server and Visual Studio)

FrontEnd HTML5 + Angular Call WeAPI --> genereate PDF by localReport.Render
All feature in RDL work fine, only IDAutomation cannot (My Custom Assembly work fine)

https://code.msdn.microsoft.com/ASPNET-MVC5-AngularJS-1f18da53


and Already config RSPreviewPolicy.config

https://www.idautomation.com/font-encoders/dotnet-assembly/sql-server-reporting-services-tutorial.html

you can see for Preview Report on the top post

What type of report is created using the barcode fonts and the .NET Assembly? RDL or RDLC? If creating an RDL and the issue is the RSPreviewPolicy.config, verify that Full Trust is given to additional CodeGroups. For now, our solution is available here.
