I made a simple app that scans a barcode and uses the value of it to look up an Id in a database table. What I want to do now is store barcode versions of all those Ids so that I can display them using a different app.
Basically, imagine that you choose an object in a table using one app and it displays a barcode that corresponds to the object's Id. The scanning app then scans the barcode (from the screen) and finds the object using the Id.
I'm not familiar with working with barcodes, how would I go about generating, storing and displaying them? We're talking potentially 50 000 objects so I'd rather not do it one by one on some website. Is there a way to generate a barcode using a value directly in the app? Like Click on Object -> Get ObjectId -> Build Barcode based on ObjectId -> Display Barcode

Hi hammerhead,
About how to use Barcode control, this blog could be your reference, please check it at here:
https://powerapps.microsoft.com/en-us/blog/make-barcode-scanning-apps-in-minutes/
About your scenario that generating a barcode using an value directly in the app, not sure how is the ObjectId looking like, may you consider to use functions Left, Mid and Right to extract the left, middle, or right portion of a string of text.
Please check the functions about Left, Mid, Right at here:

Please try it on your side and feel free reply if you need more help.
Best regards,
Mabel Mao
