How to capture whole Barcode value on Winform without using TextChanged event?

Question

When a barcode is scanned on form1, I make a call to database to get the item for this barcode and open form2 with pre-populated data.

If I use text changed event t

Answer 1

This is a result of the scanner in WedgeMode. basically it acts as a keyboard and every character scanned creates a text changed event.

There are many solves.

You could use an api supplied by the company you bought the scanner off, instead of wedgemode

However, a simple solve is to put a prefix and suffix (like the ascii codes, STX and ETX ) on the scanner (there are usually settings for this supplied by the scanner), that way you know when you have complete bar-code data.

When you see a valid barcode, then you make one event, not an event for each character scanned.
