Olan - 

Have you determined how you're going to generate QR Codes?

I found a reference in another Q&A post about a DLL named Quricol that contains methods that are easily callable from a PB application, much like you would call a Windows API function. It can create a .bmp or .png file in any of the 40 versions and four error correction levels, based on the amount and datatype of the information to be encoded.

   https://github.com/perevoznyk/quricol/releases/tag/v2.1

I've created an example app that uses the Quricol dll to create a QR Code graphics file and display it in a DataWindow. If you or anyone else is interested in examining it, reply and I'll make it available.

Hi, Olan -

Today's Trivia Tidbit: "QR" stands for "Quick Response".

To build upon Armeen's quick response to your question, have you looked in CodeXchange? Here's a link to a submission from Bruce Armstrong that uses PB 2019 R3:

   https://community.appeon.com/index.php/codeexchange/powerbuilder/284-qr-code-generator

I am somewhat reluctant to suggest links to Wikipedia, but their article on QR Codes is pretty robust. https://en.wikipedia.org/wiki/QR_code and there are many other tutorials on the subject of QR Codes to be found on the web.

Finally, I know this doesn't address your immediate need, but QR Code generation is on the product roadmap for PB 2022 (I'm surprised Armeen didn't mention this). I do not know if it will be included in the initial release or in a later release.

Hi Olan,

Check out https://www.pb.miguell.work/code/code-samples

QR Code images. Used for:https://community.appeon.com/index.php/qna/q-a/qr-code-in-powerbuilder and https://community.appeon.com/index.php/qna/q-a/qrcode-images-don-t-show-on-a-picture-control-depending-on-the-format

This is one of multiple ways to read and generate QR Codes.

• I've used a C# assembly. Powerbuilder 2019 Sample App
• combined with Visual Studio solution for Assembly

** Update ** 

In a rare and unprovoked case of sanity and common sense, I have simply attached the zip file containing the Quricol Example PB application and accompanying MS Word document to this post. I will continue to make the same zip file accessible on the below link to my Google Drive, however.

** End of Update **

Here's a link to a publicly-accessible folder within my Google Drive:

   https://drive.google.com/drive/folders/1LlncaTHnsP53v7NqhwdQVbUHrAmDbHHK?usp=sharing

A zip file in this folder contains the QuricolExample PB application and a Word document that helps explain how to use the application and some tips to explain key points regarding the application's code.

Reply/comment to this post if you experience any issues and I'll try to help.

Don’t know if there is a better way, but one idea is to get a free open source library and integrate into your app.  There are many such generators for .NET.  Here is just one example: https://www.nuget.org/packages/QRCoder/ 

PB 2019 R3 and newer has a fairly robust .NET DLL importer.  For older PB versions you could creat a COM wrapper.

Hello,

DISCLAIMER:  The attached software is developed using Windev 22.    As with any other software, this software is also comes with no warranty / guarantee to work as intended.  Use it at your own risk. 

One can use this software by calling the exe file from PB application (Topwizprogeramming's Run and Wait program is very useful to call this exe), to
1.   Print Barcode
2    To capture images via attached Webcam

How to Print Barocde.   
Call the exe with the following parameters.
Elifa4Capture.exe ls_command ls_outputfile ls_value_to_barocde ls_barcode_type
ls_command -> BARCODE ( hardcoded to make the program to print barcode )
ls_outputfile -> Barcode will be stored as an image in the output file mentioned.  Include full path name.
ls_value_to_barcode -> This value will be converted to barcode
ls_barcode_type ->  Allowed values (QRCODE / EAN 128 / EAN 13 / CODE 39 / CODE 93 / CODE 128 / CODE 11 /BAR CODE / PDF417 / DATAMATRIX /  Aztec)

How to Capture Images
Call the exe with the following parameters.
Elifa4Capture.exe ls_command ls_outputfile
ls_command -> CAPTURE
ls_outputfile -> image will be saved in this file name (only jpg is supported as of now)

Hope this tool will be useful.
Let me know about your thoughts.

Happiness Always
