Scan and Record Multiple Barcodes

[Anonymous]

Hi,

I'm creating an app where I would like to scan and record multiple barcodes. I need to be able to exit the barcode scanner in between scans as the barcodes won't necessarily be scanned continuously. Basically I need to scan a barcode, record to multiline text input then have the ability to scan additonal barcodes and have them record to the same multiline text input. 

Thank you

Pretty straightforward and I just tested to verify.  Drop your scanner button onto your app and change the OnScan code to be similar to the following:

Set(gScanData,gScanData & Char(10) & BarcodeScanner1.Value)

You can optionally drop in an If() to check if gScanData is empty so you don't get a Line Break at the beginning of course.

Then add a MultiLine Text field and set the Default to be gScanData.

This works but since the first one variable is blank, I get a blank line first and then each barcode. Is there a way to remove that?

Probably along the lines of modifying it to use IsEmpty or IsBlank on gScanValue before the assignment.  Similar to:

If(!IsEmpty(gScanValue),Set(gScanData, BarcodeScanner1.Value),Set(gScanData,gScanData & Char(10) & BarcodeScanner1.Value))
