Spawn Event when Barcode is Scanned

Im making an inventory application using c#. The application needs to be driven by the Barcode scanner ie. every time a barcode is scanned, I need an event to be spawned to take the necessary action. I am using a USB barcode scanner. I have tried using a TextChanged event in a text box, but this spawns an event for each character in the string, rather than one for the whole string.开发者_JAVA技巧 Any ideas would be appreciated.

Depending on the scanner, you should be able to have it append a new line character after each scan. Then you can have a KeyPress event that waits for a newline before consuming the barcode.
