问题 I'm looking at writing a USB barcode scanner interface to a web application (offline app). By this I mean that the scanner will be on the client machine not server. So I was wondering what the best design would be. I know I could write an ActiveX object or native plugin into some browser but this is not ideal, does anyone know if chrome extensions (in javascript) or firefox jetpack would support this kind of functionality. Any ideas? I would appreciate any leads to follow. Thanks All Guido

问题 I'm trying to implement Google Visions scanner into an app im working on. By default its a full screen activity and barcodes are tracked over the entire screen. However, I need a fullscreen camera but with a limited scanning window.

I have changed the graphic overlay so it will only display in the middle

The barcodes will just be treated as if the user had entered some text. I am not sure if the scanners will be set up to append an enter or a tab or nothing on the end, so I don't want to make an assumption on that basis. The application is a Java/Swing application. I have looked at keybindings/action maps and the like, but

问题 I posted couple other questions in regards to Zxing please DONT mark it duplicate just because they are about Zxing.. So, in my Xamarin iOS app, I am using Zxing to detect the barcode. I am using https://github.com/Redth/ZXing.Net.Mobile/tree/master/Samples/iOS as example. I am using a subview to scan for barcodes.

问题 I am using ZBar iPhone SDK in one of my projects (iOS SDK 5.1 ,XCode 4.4.1 and device running iOS 5.5.1). I am using the embedded scanner from the examples provided in the SDk itself. Now the issue which I am facing is that I successfully scan a bar code and move to another view controller ( using navigation controller).
