This code sample uses the open source QRCoder .net assembly (
github.com/codebude/QRCoder
). I created a wrapper assembly for that using SnapDevelop, and then a demo project in PowerBuilder 2019 R3 showing how it's used.
Update 07/04/2023: Updated to include sample built with PowerBuilder/SnapDevelop 2022

The code should work fine when deployed to another machine. If it's not working for you then you probably missed one of the dependencies. This is a wrapper DLL, so you no only have to deploy this DLL, but the DLL it wraps as well.

Hi Fabrizio, it also happens to me that the application (32 or 64) works correctly on a computer with the environment installed. If I bring everything (exe, pbd, xml, dll etc.) to another PC without the environment installed it no longer works, in fact the application works but the QRCODEs are not generated

The examples uploaded to the site are both compiled for .Net Standard 2.0. I believe that means .Net Framework 4.7.1.
The most recent version of the library I'm wrapping is .Net 6, so if you wanted to upgrade the component you would need to move to that.

Bruce,
What is the minimum version of .NET (framework, runtime, both) required?
Thanks,
Andy

Hello Bruce
thank you for your information about how to set ECC.
I have seen and tried in SnapDeveloper to build a wrapper with a parameter for the ECC Level but... I had not success.
I have seen that now ECC is set to Q level, that is... the QR Code can get corrupted at 25% before the code isn't readable any longer. I think it is a good setting... but sometimes it is requested a different value.
When you will have time to add the ECC parameter to your wrapper it will be fantastic. Thank you again.

Ciao Fabricio! Grazie per aver condiviso l'esempio.
Alla fine ha funzionato, ho dovuto modificare il percorso dell'assembly e installare windowsdesktop-runtime-6.0.27-win-x86.exe
Pensavo che Run Packager includesse tutto il necessario per far funzionare Assamblys.
A seconda che la PB APP sia compilata in x86 o x64, viene installato il runtime corrispondente. Nel mio caso l'applicazione รจ stata compilata in x86. Grazie per aver condiviso la tua conoscenza ed esperienza.
Grazie Mille!

Hello,
I have a complete example in this page :
fabrizioviscardi.it/powerbuilder-scripts...libreria-qrcoder.php
it's in italian language but i think you can translate easily. In every case there are two versions to download.
