Bug with Barcodes? (2D DATA_MATRIX Type)

Posted on by Community Power Pla... Microsoft Employee

Hi,

I'm scanning a GS1 DATAMATRIX type Barcode and encountered a problem/bug.

Variables:
Barcode Scanner - BarcodeScanner

Label - Barcode Scanner Result

While using the Label, and populating the text as "BarcodeScanner.Value", it appears correctly.

Ex. 2D barcode value on the product box, 011234567891123456789. When in the Label, appears as 011234567891123456789

It's a 1:1 match.

However, when I use the function Mid(), it displays, the incorrect values.

Ex. Mid(BarcodeScanner.Value,3,14) It should show 12345678911234. Instead shows, 11234567891123.

Is there a fix for this?

Thank you,

are you sure there are no (non-printing) spaces? (check the length of the string with Len(yourstring) )

@KoenJanssensPD

You're right, there is a blank value in there.

How do I go about removing it?
I try to substitute the null values, and doesn't work =Substitute(BarcodeScanner.Value,Char(0)&Char(9)&Char(10)&Char(12)&Char(13)&Char(32)&Char(127)&Char(173)&Char(160),"")

How do I identify the non-printing value from the result of the scan?

You can try something like the following code. It uses a regex to keep only numbers:
Concat(Filter(Split(TextInput1.Text,""),IsMatch(Result,"^[0-9]")),Result)
