Testing Barcodes & QR Codes in Dynamics 365 Business Central SaaS

MY QUESTION TO MICROSOFT

“I would need to understand (and to have some examples if possible) what is the best solution to use Barcode in MSDYN365 SaaS since it is not possible to install fonts on MSDYN365 SaaS to date by, In this case I would need the GS1-128 barcode font”

Example with barcode font GS1-128 (ex EAN-18)

Barcode in RDLC and Word Layout Reports

We would need to use both RDLC and Word Layout reports if possible (for WL I tried to use fonts embedded in DOCX but I did not print them, system in SaaS replace the embedded fonts barcode during printing)

I have seen these solutions \ workarounds in the forums\internet

Barcode Font in Business Central
Barcode implemented through API and without .Net Variables.

OFFICIAL ANSWER FROM MICROSOFT

.NET Azure Function or wait for Spring 2019

“Standard barcode font are not available in Dynamics 365 Business Central SaaS, the solution proposed in the blogs looks quite possible.”

Basically these could be:

Find out in the market a service – if exists – where you send a string and it returns the barcode image (encapsulated in a JSON array, or in another flavor)
Create a .NET Azure Function that takes a string and return the barcode image

#1 – BARCODE WITH “JSONMethods” and “RESTWebService”

From GITHUB Microsoft AL Question: “What is the Best Practice for creating 2D/3D Barcodes in Extensions without .NET? Currently we create an Image which will be Stream as Blob to RDLC Report Layout.”

https://github.com/Microsoft/AL/issues/744

“JSONMethods” and “RESTWebService”

Original AL Code taken from Kaufmann (GitHub), few modified for compatibly to Business Central C SaaS October’s release (area, captions, permissions etc.)

https://github.com/ajkauffmann/ALWebServiceExamples

Free Barcode generator http://www.barcodes4.me/

I Added a RDLC report to test barcode reading

Elements

Barcode Tables
Barcode Pages
Barcode RDLC Report
Codeunits for JSONMethods and RESTWebService
Permissions Sets

On “Barcode” Page

Click on “Generate Barcode” button

Barcode picture will be generated

RDLC Report

Report “Barcode List” print Barcode Pictures for reading testing

TEC-IT.COM

With “Long Barcodes”, you can have some reading error; in this case, you can use this other Free Barcode generator by “Tec-it.com”.

Example creation of GS1-12 font On-Demand

https://barcode.tec-it.com/en/EANUCC128?data=122RS_BarGS1128

Example of Direct Download from generated link

https://barcode.tec-it.com/barcode.ashx?data=122RS_BarGS1128&code=EANUCC128&translate-esc=on&dpi=96&dataseparator=&download=true

TEST WITH Tec-it.com AND WORD LAYOUT REPORT

Change “Arguments.URL” in “InitArgument” Local Procedure in this way:

local procedure InitArguments(var Arguments: Record RESTWebServiceArguments temporary; Barcode: Record Barcode)

var

BaseURL: Text;

TypeHelper: Codeunit “Type Helper”;

begin

BaseURL := ‘https://barcode.tec-it.com/barcode’;

Arguments.URL := ‘https://barcode.tec-it.com/barcode.ashx?data=’ + TypeHelper.UrlEncode(Barcode.Value) +

‘&code=Code128&multiplebarcodes=false&translate-esc=false&unit=Fit&dpi=96&imagetype=Png’;

Arguments.RestMethod := Arguments.RestMethod::get;

end;

Font dimensions: you can define dimensions (DPI, WIDTH, HEIGHT) in this way:

Create a new Word Layout for report

BARCODE – WORD LAYOUT REPORT – DESIGN MODE

Launch the Word Layout Report

RESULTS

Printed from Dynamics 365 Business Central SaaS

Example of “Production Order Report” in Word Layout with Barcode

ASPOSE.BarCode

Another great resource is ASPOSE.COM

https://www.nuget.org/packages/Aspose.BarCode/

This Technology Based on Entity Framework

#2 – BARCODE AND QRCODE WITH AZURE FUNCTIONS (FUNCTIONS APPS)

2A – TESTING “AZURE FUNCTIONS”

What are Azure Functions?

“Azure Function (Function App) is one elegant way of replacing your .NET interoperability code with something else is by using Azure Functions”, as defined by Microsoft (updated definition): Azure Functions is a serverless event driven experience that extends the existing Azure App Service platform. These nano-services can scale based on demand and you pay only for the resources you consume.”

Azure Functions in Dynamics NAV and Dynamics 365 Business Central

Great Demo “How-to” Call Azure Functions on Dynamics NAV\Business Central on Vjeko Post http://vjeko.com/invoking-azure-functions-al/

Azure Functions is a serverless event driven experience that extends the existing Azure App Service platform. These nano-services can scale based on demand and you pay only for the resources you consume.”

SCENARIO: “Create a .NET Azure Function (Azure App) that takes a string and return the Barcode or QR Code images”
