I want to do QR Scanner in webform VB.NET. I want to do like this press a button to open the camera then scan the QR Code. I found one package call QRCoder can generate the QR Code. My problem is I did not find the way to decode the QR. Does anyone know how to do it? Thanks in advance.
You need to scan the QRCode in your front-end, not the back-end. You can use this library to scan a QR Code and send to your back-end.

I'm curious to know if you can store information like First Name, Last Name, Username, that sort of thing on a QR code alongside a code/script that when the QR code is scanned the script runs and automatically fills in those fields on an app. If so are there any suggestions on how I can achieve this.
First, thank you for taking the time to read and help.
We have a third party barcode scanner on an android device. The device reads the barcode and sends the data back as keyboard input. I have been looking for a way to just capture all text input, but I haven't been able to find a global text input listener.
Does anyone know a way I can do this without forcing the user to click into the input box (ideally I would just capture and never present the input to the user), and then scanning the barcode?
Thank you!
What you want is to capture the raw keyboard events. It's the same as getting input from an external usb/bluetooth keyboard. You are correct that this won't work without a native module to capture those system-level events.
This react native library can do the trick:

I am creating a system that when the user uses the barcode scanner, it will automatically fill into a specific field.
Example: The cursor is in the textfield4, when I click the barcode scanner, the input should be placed in textfield1.
Thanks in advance for the help.
I have downloaded the SDK but I'm having a compatibility issue. I am using symbol barcode scanner LS2208. The SDK Provided by motorola isn't working.
I tried catching the time of input when enter is pressed. 1st scan is good, after that it leaves out the 1st few characters behind.
i wrote a (visual basic.net-2008) desktop app that allows ham radio operators to enter a call,
such as WA0H, and the program gives the ham's location (springfield, mo.).
you can download the program free from my website .. www.wa0h.com
i want the program to display the ham's location on a google map using google's api-v3.
i have created an (html/javascript) webpage, where you enter the location in a form box,
click a (find) button, and the app displays the map ok, including a marker pin on the map.
??? how do i run the (webpage) from inside my (vb.net) program ???
my vb.net program needs to:
1 .. pass the address to the webpage
2 .. click the webpage (find) button
according to the google maps (developers) website, they want questions posted to stackoverflow.
thanks for your time.
1-First you need to create pin on the map
i suggest using Google Static Maps API as in hear : https://developers.google.com/maps/documentation/static-maps/intro#quick_example
for the example use this
https://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=600x300&maptype=roadmap&markers=color:blue%7Clabel:S%7C40.702147,-74.015794&key=YOUR_API_KEY
then you get something like this
https://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=600x300&maptype=roadmap&markers=color:blue%7Clabel:S%7C40.702147,-74.015794&key=AIzaSyDnw6k3UjE2qZ5nLnI8cKghaEEdCXV0PUI&signature=5xiF2jgoXwFonsjew0PmtZdSTHU=
2-you need to open this page using web browser.
to use "WebBrowser" inside of toolbox, drag and drop it then set ScriptErrorsSuppressed to true
to set webbrowser url you can use webbrowser1.navigate("your url as string")
