Barcode Reader - no output value to text box

[Cal3]

Hi All,

I'm trying to create a simple asset registry, part of this is has a barcode scanner function to make life easier.  The problem is that I can't for the life of me figure out how to get the value scanned to output to a text box.  Also apologies in advance this is my first powerapp.  I've set the following:

Scan Button: OnScan = Set(varScans, BarcodeReader1.Value) - however with this when I put in .Value it doesn't recognise it.

Text Bxo: Default = varScans - But doesn't recognise it.

I'm probably wrong on multiple levels here but any help would be appreciated.  Thanks.

Thanks for your suggestion.  I'm still getting the same error.  Everything I look at has "barcodescanner" where as I have barcodereader1 when I add the item.  I'm not sure if that would make a difference here.

@Cal3 ,

Values have changed - you need

Set(varScans, BarcodeReader1.Barcodes)

[Cal3]

@WarrenBelz I was thinking that as well.  Thanks.  Would you know how I get this to show up in the text box?

@Cal3 ,

You can actually put this

Set(varScans, Self.Barcodes)

which produces a Table with two fields - Value being the barcode and Type being the type of barcode scanned. As multiple codes can be present, to get a Text value, you can either (for a single code) scanned

Set(
   varScans,
   First(Self.Barcodes).Value
)

or for multiple barcodes

Set(
   varScans,
   Concat(
      Self.Barcodes,
      Value,
      ", "
   )
)

@WarrenBelz thank you so much, that worked, I've been at this for so many days thinking that I could figure this out.  Finally caved in and asked the question and bang... the community provides.  Thanks again.

Hi ,

If a screen has two barcode reader and two data card ,how can I write their formula?

Button BarcodeReader1:OnScan=Set(varScans,Concat(Self.Barcodes,Value,ThisItem.'Inspected by'))

DataCardValue48:Default=varScans

Button BarcodeReader2:OnScan=Set(varScans,Concat(Self.Barcodes,Value,ThisItem.'D/O / P/O'))

DataCardValue49:Default=varScans

When I selected a button BarcodeReader1 to scan the item, a result was come out in two of data card.

@Tan_Jia_Ying ,

You need two variables.

I'm Sorry. What is it?
