barcode-scanner

问题 I am trying to implement a barcode scanner using Angular 4, using this plugin - https://github.com/isonet/angular-barcode-scanner. In my scanner.component.ts page I have; import { Component, OnInit} from '@angular/core'; import 'angular-barcode-scanner'; ... In my app.module.ts file; .... import { BarcodeScanner} from 'angular-barcode-scanner'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, FormsModule, HttpModule, RouterModule.forRoot(routes), LoginModule, SignupModule

问题 I'm followed this IBM Worklight article instructions - link. On Eclipse - when I try to run BarcodeScannerSampleBarcodeScannerSampleAppAndroid - I get message box with title - "Android Launch" , that says: "Your projects contains error". At Markers window I get this Error: The container 'Android Dependencies' references non existing library 'D:\Users\MyUser\workspaceNew\CaptureActivity\bin\captureactivity.jar' BarcodeScannerSampleBarcodeScannerSampleAppAndroid Build path Build Path Problem

问题 I am using a Microsoft.NET text box in Windows Forms 2.0 using C# for data from a USB based Bar code scanner. The user does not want the text box to accept inputs from keyboard. How can i apply a filter such that only inputs from the USB are accepted and the keyboard disabled during this session ? Thanks. Comment added one hour after: I got some thing on this and this which i need to study. To those of you who want to know why this redundancy, the user also wants an option to configure the

问题 As Peter Duniho points out in a comment here, I was fixated on a red herring when I should have been focusing on something else altogether. When I use Symbol.Barcode.Reader and Symbol.Barcode.ReaderData in one form, they work fine. I use them as I document here. However, when I go from one form that uses the barcode scanning code to another one that also does, all Dallas breaks loose. I get the following exception in the second form, on startup: Symbol.Exceptions.OperationFailureException:

问题 Essentially, I'm looking for a 1D bar-code scanner that I can program, either through provided software or some sort of programming language, that will read a bar-code and format the resulting string. I have already tried the Datalogic Gryphon GD 4130 scanner and it didn't work well with what we needed it to do, and I thought the software they provided was hard to use. Price isn't an issue either. So any recommendations would be great. 回答1: The Honeywell Voyager 9520/40 line worked well for

问题 I have issues with .NET CF 3.5 application on Windows Mobile 6.5 on Motorola MC55 device. We have around 150 devices which run a barcode scanning application written in C# Compact Framework 3.5. The application is for barcode scanning and communication with SOAP WebService through WIFI/GPRS. Every day around 10-15 devices go corrupted (file system errors) and need to be flashed again. Motorola support claims it is a fault of our application. For us this is not an argument. What can be source

问题 I have a Motorola DS4208 barcode scanner that I have been using in combination with a program. The problem is I want to prefix the scans with some character so that the program knows an item was scanned by the scanner. I've tried following the user guide's instructions but instead of prefixing a character, the scanner prefixed a carriage return. 回答1: are you referring to the scanner product reference guide, you should be able to scan a series of barcodes to configure the scanner with a prefix

问题 Our application presently uses the Motorola/Symbol DS6707 Digital Image Scanner for both image capture and barcode scanning. We communicate with the scanner via the Moto SNAPI driver. Since this is specific to the Motorola/Symbol scanner, I am considering a rewrite using a more generic interface, such as OPOS. This is in a C/C++ application. We also have a Honeywell imaging scanner in house that we are testing with. This model (Xenon 1900) also an supports both imaging and the barcode

问题 Is there a way to read from a USB barcode reader in one interface & at the same time use the keyboard & mouse to write data in a diffrent interface application? My application is running as web application. Also can it work under unix? 回答1: Under Linux it's easy; configure Xorg such that the reader is not a core input device, then use the event subsystem to read the input events directly from the reader. 来源： https://stackoverflow.com/questions/4764274/need-barcode-keyboard-to-work-separately

问题 I have a problem with the barcode scanner plugin (I'm not a genius and I don't know well how to programm a web-app.). I use phonegap and cordova and I've tried to do a web-app that scan a barcode after a click on a link. I've installed the plugin, before with this command line: cordova plugin add cordova-plugin-barcodescanner and I write this js code: function scan(){ cordova.plugins.barcodeScanner.scan( function (result) { alert("We got a barcode\n" + "Result: " + result.text + "\n" +
