Web Forms :: How To Read QR Code Value From Scanner
May 7, 2015
I need to build a webform app that can generate cards for customers. Each card will have a unique QR code or barcode on it so customer can scan it to check-in and check-out when they come into the store. To generate QR code, I found this article on our website and I think it will work with the “generating card” step: [URL] ....
So a new customer come in, we will enter customer’s info and save it to a SQL server DB, get the ID returned after inserted that record and use it to generate the QR code and print out the card.
My question is on the “reading card” step: let’s assume a customer has a card and they come to the store, what happened after they scanned it? I mean how the scanner works? People say that the scanner acts like a keyboard, is that true and how?
Basically I want to make the “scan action” to act like a button click event (or enter key pressed) so I can put my logic code in, something like this:
That’s it, I just want to save check-in and check-out time now. Is it possible and how to archive, what scanner should I buy?

BARCODE_NUM,LASTNAME, FIRSTNAME. Below is a dummy example when students scan their Student_ID into barcode reader. I get the following data from the barcode reader.
" %C9887688767876^Smith/John^5656656556565?;C9887688767876=3434354450000? " When the user scan their Student ID into TextBox1, i want to only display BARCODE_NUM which is C9887688767876 from the example. Also When the user scan their Student ID into TextBox2 , i want to only display LASTNAME which is Smith from the example. When the user scan their Student ID into TextBox3, i want to only display FIRSTNAME which is John from the example.

Solution: I end up creatting a WCF that accepts a get/post request, then place JQuery within the html page that retrieves the value and hands it off to the web service
I have a html page like below where I will be doing posting to a web site for registrations and my credentials are not suppose to show on the client side.
My question is how/what is the best way of reading the values from code behind or web service or any other way ?
now i need to develope the application to display the images when ever the files are scanning in the scanner machine. i want to display the images directly from the scanner.
I am having an issue with one of my projects where I get the HTML source code from the page. I usually use the URL string and a Get method to get the source code like below:
[Code]....
The problem is that the page I am working with currently actually does a page redirect using a javascript function on the page like so:
[Code]....
I have been trying to figure out how to read in the the first page's HTML source code, post that HTML source back so it redirects, and then get the second page's HTML source code.
I have a txt file, in which read only property is true. When I try to write some text in that file through the vb coding, it's through the error. I have shown the code below.
Dim fs As FileStream = File.OpenWrite(HttpContext.Current.Server.MapPath("Include/CacheKeyFile.txt")) Dim sw As New StreamWriter(fs) sw.Write("Menu setup updated by " & value & " on " & DateTime.Now.ToString()) sw.Close() fs.Close()
I found the cause of the error. If we set the Write access property to false, we can open the file and write it without showing the error messages.
I need to remove the Read only property for a file through the vb. Net code. Is it possible? Can we set the read only for txt file before open and write operation?
I am creating a web application using c#. I need to access the values available in a barcode scanner and display it in the web page. The user has a Barcode scanner, which contains the Student Id's. The Barcode scanner is connected to the user machine. Is it possible to access the scanner and access the student id available in the scanner and display it in the aspx page. After retrieving the values and displaying it in page, the students id's available in the scanner has to be deleted.
I have a textbox on an asp.net page. I use a barcode scanner to get the barcode number into that textbox. I need to then automaticaly fire an event directly after the text box recieves that input. the only event that is exposed is the TextChanged event which doesnt achieve what i need. I am using c# for the code behind.
is this c# code intended to read local client files?System.IO.FileStream content = System.IO.File.Open("c: est.txt", System.IO.FileMode.Open);It gives me error FILE NOT FOUND
