Hello,
I'm trying to use the new Barcode Reader to output the scan to a text box.
I have tried following the solution here but i can't get it to work https://powerusers.microsoft.com/t5/Building-Power-Apps/Barcode-Reader-no-output-value-to-text-box/m-p/2092469#M522995
If someone could kindly share how I can click scan, then the barcode scanned to appear in the text box.
Thanks
Hello, @jap11 , the barcode scanner control has a property called OnScan, use this formula in there:
Set(glbVarScan, BarcodeReader1.Barcodes)
Then your your Label Text property, put the glbVarScan
I am primarily available on weekdays from 6-10 PM CT and 5-10 PM CT on weekends.

Hello @AhmedSalih - thanks for responding!
I'm still getting an error message when trying this?
Is there still something I'm doing wrong?
@jap11, is this a Teams PowerApp?
@jap11, use this in the Text property: First(glbVarScan).Value
@AhmedSalih thank you, that's worked!
@jap11, Glad it did 🙂
@AhmedSalih Apologies - one thing I've noticed is that if i scan a barcode and it outputs to the text box, if i leave the screen and return back, the last scanned code still appears.
Is there anyway to reset this so the field is empty again if i leave the screen.
@jap11, try to use the Last function instead of the First: Last(glbVarScan).Value
@AhmedSalih unfortunately it still displays the last scanned value.
@jap11
, after I gave it a thought, and with the new way yhat barcode control now works, you will need to use collection: In the OnScan: Collect( colScannedItems, {ScannedItem: First(BarcodeReader1.Barcodes).Value, ScannedTime: Now()} )
In the Text: First(SortByColumns(colScannedItems,"ScannedTime",SortOrder.Descending)).ScannedItem
