问题 I am newbie to iPhone application. But recently I saw a post asking for Barcode Reader for 3G iPhones. And people(including me) have referred to zxing which works on 3GS or later and if you want to make an appication for 3G then better you buy it from QuickMark or RedLaser to get 3g scanning. So I planned something and need several information from you all There are lots available on appStore. One of them is pic2shop(Which is a free application). But what I want to know is: What exactly is it

问题 I have implemented ZXing to my iOS-app, however I am questioning it's maintainability as not long ago it was announced that ZXing to iOS is retiring: Retiring C++, Objective C code I've also read that there might be compatibility issues with the newer phones iPhone 5S.. Also running Xcode's static code analysis on the Zxing-library reveals memory errors, I'm not sure if these errors are false positive or not, but they make me doubt Zxing even more. Further, the performance of Zxing compared

问题 I have a bar-code scanner which is connecting through RS232 serial port. I need to write a program to connect this device with the PC and transmit data. I already wrote some basic methods to initialize a communication link and tried to test by sending a BEEP command to the device but it is not beeping as expected. So I think there is something wrong with my source code. Please somebody help me complete the source code. Below is the written source code 01)DeviceRS232.h #ifndef DEVICERS232_H

问题 I am trying to enable a PHP website to recognize barcode input. I will load a web page in a browser, the focus (cursor) is set to recieve input into the text box. I will be having a barcode reader/scanner plugged into the PC and will scan the barcodes one-by-one using the scanner. Would the information from the barcode can be put into the text box of the web page ? The important question is that how can I read the output from the scanner using PHP ? Please advise. 回答1: Had a similar problem.

问题 I am using the ZXing by the following code ContinuousCaptureActivity, and the zxing using (by default) the back camera to scan, how to make it scan using the front camera ? 回答1: set extra SCAN_CAMERA_ID to the ID of the camera you want usually 1 for the front one. for example intent.putExtra("SCAN_CAMERA_ID", 1); 来源： https://stackoverflow.com/questions/40141833/how-to-make-the-zxing-scan-using-the-front-camera-not-the-back-camera-in-android

问题 I’m building an app for paying parking tickets. The problem is that we have a specific type of barcode that AVFoundation can’t read. I tried to found other frameworks to replace the AVFoundation, but turns out all of them use AVFoundation underneath. The only framework I found capable of reading it is the ZBar, but we’re not planning to use it since it hasn’t been updated for 6 years. Do you guys have any idea why it isn’t working?

问题 I'm messing around with a Honeywell 4600 barcode scanner in python, configured as a serial device. All is well and I can read barcodes with it, but I would like to test the serial trigger option instead of pressing the trigger all the time. The manual is very brief on this feature and only states "SYN T CR" has to be written to the device to activate the serial trigger ser.write('SYN T CR') does not seem to do much. Can someone point me in the right direction? Thank you! 回答1: This happens
