ASP.NET QR Code Barcode Introduction
QR-Code is a matrix / 2D (two-dimensional) symbology developed by Denso Wave. It is also known as Quick Response Code, Denso Barcode, QRCode, JIS X 0510, ISO/IEC 18004.
Compatibility: Barcode for ASP.NET control dll is compatible with ISO/IEC 18004 (Second Edition 2006-09-01) bar code symbology specification for QR Code printing. Thus QR Code images generated are readable for all scanners / barcode recognition tools.
Encoding: QR-Code bar code is widely used for its versatility in data encoding, which include: numeric and alphanumeric characters (A-Z, a-z, 0-9), Kanji characters (JIS X 0510), and byte data (default is ISO/IEC 8859-1).
QR Code bar code can encode multiple types of data, including numeric and alphanumeric characters (A-Z, a-z, 0-9), Kanji characters (JIS X 0510), and byte data (default is ISO/IEC 8859-1, including characters from English, German, French, Italian, Spanish, Portuguese, etc.)
To know more, please refer to .NET QR-Code Introduction.

How to Stream QR-Code Bar Codes in ASP.NET Web Applications?
BarcodeLib QR Code ASP.NET generator supports streaming QR-Code images in ASP.NET in two ways.
  1. Create QR Code through Buildin ASP.NET Barcode Application.
    • Download & unzip the trial, and copy barcode folder and its contents to your IIS folder, eg. C:\inetpub
    • Create a new virtual directory in your IIS named "barcode", and connect it to the above "barcode" folder pasted in inetpub.
    • Restart your Microsoft IIS and navigate to: http://YourDomain:Port/barcode/qrcode.aspx?Data=0123456789&ModuleSize=3&LeftMargin=12&RightMargin=12&TopMargin=12&BottomMargin=12
      Here is the generated QR Code barcode image:

      To make further adjustment for the QR Code image, please view web stream URL parameters for QR Code here: .NET QR-Code Generator Property Settings
    • If you want to insert this QR Code image in your aspx or html page, please pass the url to IMG tag or src value.
      <img src=http://YourDomain:Port/barcode/qrcode.aspx?Data=0123456789&ModuleSize=3&LeftMargin=12&RightMargin=12&TopMargin=12&BottomMargin=12 />
      This method will not generate any barcode images in your IIS server side.
  2. Create QR Code through ASP.NET web form controller.
    • Intall ASP.NET barcode controller to your .NET project by adding reference.
    • Add barcode library to your Visual Studio toolbox.
    • Open barcode in your unzipped trial package, and copy files "qrcode.aspx", "qrcode.aspx.cs" to the aspx page where you will be generating QR Code images.
    • Now drag QRCodeASPNET to your ASP.NET web site, and change QR code settings if necessary in the Properties window.
    • Run the project to view the generated QR Code barcode on your aspx page.
