Drop Meaningless Characters from BarCode Reader

Posted on by bgeorge76

I have an app that I've been working on enhancing with the ability to use the Barcode Reader to read product numbers and enter them in to a text input field. I have the basics of this function working by assigning the following:

barCoilID: OnScan.Set(varCoilID, First(barCoilID.Barcodes).Value)
TextInput: Default.If(varCoilID = "", Parent.Default, varCoilID) (the text input will only accept numbers)

This works as intended however, our computer system puts a leading "s" in the barcode, which means nothing to our users. The product ID as a format of ######. I can use a Right(varCoilID, 6) in the Default property but I've found a few products that only have 5 digits. It's rare for that to happen, but I want to take as much error out of this as possible.

Does anyone know a way to just drop the "s" from the scan without using a Right Function? I've tried using a Substitute function (Substitute(varCoilID, "s", "") in both the OnScan and Default properties and it doesn't seem to work. Any ideas would be greatly appreciated.

Hi @bgeorge76,

The Substitute function should work - please keep in mind that this is case sensitive and will remove all occurrences within the scanned value.

//Barcode reader OnScan Set( varCoilID, Substitute( First(Self.Barcodes).Value, //Make sure this is the correct case "s", "" ) )

Alternatively you could use the following when s can occur multiple times but only the first one needs to be removed.

Set( varCoilID, With( { wBarCode: First(Self.Barcodes).Value }, Right( wBarCode, //Should s always occur as a prefix, replace the Find() function with 1 Len(wBarCode) - Find("s", wBarCode) ) ) )

If this solves your question, would you be so kind as to accept it as a solution & give it a thumbs up.

Thanks!

Both of those looked promising, but neither worked. Both returned errors of unexpected values.

@bgeorge76 my apologies, I had 1 closing bracket too many.

I adjusted my initial comment accordingly. Would it be possible to try again?

I just found the same thing. Tried both routines and got the same error that s##### could not be converted to a number.

@bgeorge76 I am unfortunately not able to recreate that error. Where does this error exactly occur since we don't do any numeric conversions in the code mentioned above?

Nevermind, I found the issue. It was a case sensitive error on my part. The barcode was returning a uppercase S, not a lowercase and I overlooked it. Your first example works perfectly. Thank you so much!

That indeed explains the error, thanks for the update!

Glad I was able to help! 😊
