Output barcode screenshot (QR Code 2D symbology barcode type):

QR Code symbology. QR Code initially was used for tracking parts in vehicle manufacturing, but now QR Codes used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (known as mobile tagging).

Important: you can also use BarCode Windows Forms or Web ImageControl instead. To use the Windows Formscontrol in Visual Studio please open Toolbox and open “Bytescout Software” tab and drag-n-drop “BarCode” control into your WinForms or ASP.NET application (in design mode)

The video tutorial how to make QR Code:

Visual Basic:

Imports Bytescout.BarCode

Module Module1

Sub Main()
‘ Create new barcode
Dim barcode As New Barcode()

‘ Set symbology
barcode.Symbology = SymbologyType.QRCode

‘ Set value
barcode.Value = “this is a test string”

‘ Save barcode to image
barcode.SaveImage(“result.png”)

‘ Show image in default image viewer
Process.Start(“result.png”)
End Sub

End Module

Visual C#:

using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;

using Bytescout.BarCode;

namespace Sample
{
class Program
{
static void Main(string[] args)
{
// Create new barcode
Barcode barcode = new Barcode();

// Set symbology
barcode.Symbology = SymbologyType.QRCode;

// Set value
