to distinguish it from normal textboxes, and have a help text associated and available at all time that improves clarity. Give it a different color, border, size etc. a watermark in the textbox ("Don't type, scan!" or something in that order). I am including as an option as it is simple and if made correct also effective (there's no right answer of what is correct unfortunately).Īpproached could include f.ex. Usability improvements: make it visually very clear that bar-codes must be entered with a scanner and not typed. This way you can first buffer input, measure time and if within a set time-out value, inject the line into the textbox. (you can detect pasting by overriding the ctrl + v as in the next option).Ĭombine option 2 but instead of measure in the textbox tap into the ProcessCmdKey() function (by overriding it) and measure there if textbox has focus. You can turn this feature on or off in the Camera settings.
SEND ANYWHERE QR SCANNER CODE
You now have the most conveniently placed QR code reader on your device. A popup will appear just tap this to get deep linked in or to visit a URL.
Find a QR code you would like to scan and point the camera towards the QR code. In addition the checksum of the barcode (if you use one that contains that) can be used to do an extra validation in addition to time measurement. Open your Samsung One UI device's stock camera app. If timed-out just reject/clear the input. Send Anywhere: Easy, quick, and unlimited file sharing Features Transfer any file type without altering the original All you need is a one-time 6-digit key for an easy file transfer Wi-Fi Direct: transfer without using data or the Internet Easy link sharing via all Social Media and Messenger Apps Reinforced file. Measuring the time used in the textbox by counting key-presses (use CR+LF as a measure point as these are sent by the scanner as well) can give you one method to distinguish if a human is typing (unless there is one typing fast as f) or the content was injected. Barcode-scanners inject a sequence (line) pretty fast compared to typing.
SEND ANYWHERE QR SCANNER SERIAL
One connected to a serial port (or emulated one via USB as serial-ports are not so common anymore) gives you full control on where the input comes from.Ĭount number of chars typed by time. As most barcode-scanners emulate keyboard strokes there is no way to directly distinguish a barcode scanner input from a keyboard input (see next option) without going low-level (see last update). Get a barcode-scanner that is connected to a serial-port (raw serial device read by a COM port).
