Matrix QR Code Barcode Introduction
QR Code, also named as Denso Barcode, QRCode, Quick Response Code, JIS X0510 & ISO/IE18004, is a widely-used two-dimensional barcode symbololgy with fast readability and large storage capacity.
QR Code Encodable Character Set
- Numeric: 0 - 9
- AlphaNumeric: 0 - 9, upper case letters A - Z, and punctuation characters (space, $ % * + - . / :)
- Byte data: (ISO/IEC 8859-1) encoding characters at 8 bits per character
- Kanji Characters
QR Code Barcode Generation in ASP.NET Using VB
With this Barcode Generator Control, you can generate QR Code barcode image in ASP.NET websites. QR Code barcode generation can be realized by dragging and dropping the control to Toolbox in your Visual Studio, compiling VB barcoding sample code, or through your IIS. For detailed operations, you may refer to this guide for barcode generation using VB class in ASP.NET. QR Code Barcode Generation in .NET WinForms Using VB
There are two ways for generating QR Code barcode image in .NET Windows Forms applications. One way is to directly drag the barcoding control to a Windows Form in your Visual Studio and change barcode settings through the Properties panel. The other way is using VB programming. Here is a tutorial for creating barcodes using VB class in .NET WinForms. QR Code Barcode Generation in Crystal Reports Using VB
Developers can create QR Code barcode images in Crystal Reports through this barcode component. It is easy to create QR Code barcode through VB encoding and no barcode fonts or third party tools are required. To get more information, you can view the developer guide for VB barcode generation in Crystal Reports. QR Code Barcode Generation in RDLC Reports Using VB
This .NET Barcode Generator supports QR Code barcode generation in RDLC Reports. The generated barcode image is entirely compatible with latest barcode standards. You can also change QR Code barcode image properties through VB demo code. Please view this VB barcode generation guide in RDLC Reports for more details. QR Code Barcode Generation Using VB.NET Demo Code
You can generate QR Code barcode image using the following VB demo code in .NET applications. According to your needs, you may make some adjustment to the QR Code parameters. Before using the demo code, you need to add reference from the trial package to your project. VB Sample code
Dim qrcode As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode
qrcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode
'QR Code Version options, V1-V40 supported.
qrcode.QRCodeVersion = KeepAutomation.Barcode.QRCodeVersion.V10
'QR Code Version Error Correction Level, 4 modes (H, L, M, Q) supported.
qrcode.QRCodeECL = KeepAutomation.Barcode.QRCodeECL.H
'QR Code data mode, supporting AlphaNumeric, Auto, Byte, Customer, Kanji, Numeric
qrcode.QRCodeDataMode = KeepAutomation.Barcode.QRCodeDataMode.Auto
'Set QR Code valid input: All ASCII characters, including 0-9, A-Z, a-z, special characters. Length: variable.
qrcode.CodeToEncode = "vbQRCode"
'QR Code unit of measure: pixel, cm and inch
qrcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel
'QR Code image resolution in dpi
qrcode.DPI = 72
'QR Code Size-related Settings
'QR Code bar module width (X dimention)
qrcode.X = 2
'QR Code bar module height (Y dimention), Y=X
qrcode.Y = 2
'Image margin size, minimum value is 4X on all four sides according to specification.
qrcode.LeftMargin = 8
qrcode.RightMargin = 8
qrcode.TopMargin = 8
qrcode.BottomMargin = 8
'Generate Data Matrix in Png, Jpeg, Gif, Bmp, Tiff image formats.
qrcode.ImageFormat = Drawing.Imaging.ImageFormat.Png
