barcode

问题 since I know this side most of my questions have been answered be using the search. But this seems to be a special one. I am new to Google Android development, so I want to learn by doing. I want to create an app, that scans barcodes and displays a list of possible products. I am using ZXing (got this from here! ;)) to scan the barcdes. Works perfect.

问题 I have a web page with one input text for the barcode content and a select for the barcode type. So using the database, it is possible to generate the barcode in the good format. A normal final user don't know which barcode as which type, but the barcode reader knows and can send this type as a keyboard input. The problem is that I don't know how to change from the input to the select. If I use, the \t , it prints a tabulation in the input instead of switching from a input to the other. If I

问题 I need to scan a barcode with ASCII 29 (group separator) into an HTML input field, and replace all the group separators with |. The following JavaScript function works when I first scan the barcode into Notepad++ and then copy it to the input field, but not when the barcode is scanned directly into the input field. What's the problem? var barcode = document.getElementById('barcode').value; barcode = barcode.replace(new RegExp(String.fromCharCode(29), 'g'), '|'); alert(barcode); 回答1: On my

问题 I am using AVFoundation and AVCaptureMetadataOutput to scan a QR barcode in iOS7, I present a view controller which allows the user to scan a barcode. It is working fine, ie. a barcode is being scanned and I can output the barcode string to console. But it keeps scanning over and over again, see screen shot. What I want it to do is scan the barcode just the once and then dismissViewController. Here is my code for the delegate method: - (void)captureOutput:(AVCaptureOutput *)captureOutput

问题 I'm currently writing an application for Windows Mobile which needs to be able to pick up key value pairs from 1D barcodes (configuration settings). The less barcodes need to be scanned, the better. Sample input: ------------------------------ | Key | Value | ------------------------------ | 12 | Söme UTF-8 Strîng | | 9 | & another string | ------------------------------ I thought of the following algorithm: 1. Concat the key value pairs and encode the values with Base64 So we would get

问题 I am looking at CIDetectorTypeQRCode. How can I detect other types of barcodes? I can read other barcode types via AVMetadataObjectType, however I want to do the same with CIDetector. I am trying to achieve real time highlighting of the barcode. Trying for a sort of zoom in effect before my AVCaptureMetadataOutputObjectsDelegate achieves a full lock and read of the code. 回答1: CIDetector has only following types to detect, So we can't use it to detect another type of barcodes.
