On-Screen barcode & QRCode Decoder

Details:

Occasionally when browsing the web I'd come across a QR Code or barcode and wonder what it said. Last fall (2008) I found Google's ZXing project which aims to solve this very problem. I wrote up a quick program (using their libraries) that would take a screen shot of your desktop and tell you what any detected codes say.

The program is written in Java. You shouldn't need anything other than a basic install of Java 1.6. Once you have it downloaded to your system you should run it with java -jar /path/to/file/DecodeFromScreen2.jar. This will instantly take a screenshot and tell you what it finds. For maximal utility I recommend making a shortcut to it somewhere easy to find.
