Detect when input box filled by keyboard and when by barcode scanner.

How I can programmatically detect when text input filled by typing on keyboard and when it filled automatically by bar-code scanner? Well a barcode won't fire any key events so you could do something like: $('#my_field').on({ keypress: function() { typed_into = true; }, change: function() { if (typed_into) { alert('type'); typed_into = false; //reset type listener } else { alert('not type'); } } }); Depending on when you want to evaluate this, you may want to do this check not on change but on submit, or whatever.

问题 I am writing a barcode reader app but I am unable to detect linear type barcodes, ie code 128. I have no issues with Qr codes, EAN13 types and ISBN types. My code is pretty straightforward: func metadataOutput(_ output: AVCaptureMetadataOutput, didOutput metadataObjects: [AVMetadataObject], from connection: AVCaptureConnection) { if metadataObjects.count != 0 { if let object = metadataObjects[0] as? AVMetadataMachineReadableCodeObject { if object.type == AVMetadataObject.ObjectType.qr { if

问题 I developed a BarcodeScanner app with ZXING library. for that I downloaded the complete library and added it to my proj and called an Intent with URI:"com.myproject.vinscan.client.android.SCAN". but later I found that, instead of downloading and including all packages of ZXING into our proj, we can just use the URI for Inetnt as "com.google.zxing.client.android.SCAN". My doubt is, how is it working without the libraries. It is working even in offline mode(without WIFI/GPRS). are the libraries

How to distinguish between multiple input devices in C#

半城伤御伤魂 提交于 2019-11-26 20:22:07
I have a barcode scanner (which acts like a keyboard) and of course I have a keyboard too hooked up to a computer. The software is accepting input from both the scanner and the keyboard. I need to accept only the scanner's input. The code is written in C#. Is there a way to "disable" input from the keyboard and only accept input from the scanner? Note: Keyboard is part of a laptop...so it cannot be unplugged. Also, I tried putting the following code protected override Boolean ProcessDialogKey(System.Windows.Forms.Keys keyData) { return true; } But then along with ignoring the keystrokes from

问题 Is there a way to read from a USB barcode reader while ignoring the keyboard and not knowing the PID or VID of the USB scanner? I know that there is a way of differentiating between USB scanner input and keyboard input by using the VID and or PID of the USB scanner; this was done using code from http://nicholas.piasecki.name/blog/2009/02/distinguishing-barcode-scanners-from-the-keyboard-in-winforms/ But is there another solution to differentiate between keyboard and USB scanner without
