Barcode Program in C#,Vb.Net

You can use a barcode generator for C#.Net and VB.Net called ka.barcode for .net suite.You can search it in google to get it,and here i can give you some sample codes,when you find that programming,you can use thiese codes to test it.

C# Sample code

BarCode qrcode = new BarCode();
qrcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode;

//Select a QR Code supported data mode according to your code:
//AlphaNumeric: for 0 - 9, upper case letters A - Z, and nine punctuation characters space, $ % * + - . / :
//Byte data: for (ISO/IEC 8859-1) encoding characters at 8 bits per character
//Kanji Characters (JIS)
//Numeric: for digits 0 - 9
qrcode.QRCodeDataMode = QRCodeDataMode.Auto;

//Input your QR Code encoding data:
qrcode.CodeToEncode = "C#QRCodeGenerator";

// Unit of measure, pixel, cm and inch supported.
qrcode.BarcodeUnit = BarcodeUnit.Pixel;
// QR Code image resolution in dpi
qrcode.DPI = 72;
// QR Code bar module width (X dimention)
qrcode.X = 3;
// QR Code bar module height (Y dimention), Y=X
qrcode.Y = 3;

// QR Code image left margin size, the minimum value is 4X.
qrcode.LeftMargin = 12;
// Image right margin size, minimum value is 4X.
qrcode.RightMargin = 12;
// Image top margin size, minimum value is 4X.
qrcode.TopMargin = 12;
// Image bottom margin size, minimum value is 4X.
qrcode.BottomMargin = 12;

// QR Code orientation, 90, 180, 270 degrees supported.
qrcode.Orientation = KeepAutomation.Barcode.Orientation.Degree0;

// QR Code barcode version, valid from V1-V40
qrcode.QRCodeVersion = QRCodeVersion.V5;

// QR Code barcode Error Correction Lever, supporting H, L, M, Q.
qrcode.QRCodeECL = QRCodeECL.H;

// QR Code image formats, supporting Png, Jpeg, Gif, Tiff, Bmp, etc.
qrcode.ImageFormat = ImageFormat.Png;

// Generate QR Code barcodes in image format GIF
qrcode.generateBarcodeToImageFile("C://barcode-qrcode-csharp.png");

/* Create QR Code barcodes in Stream object
qrcode.generateBarcodeToStream(".NET System.IO.Stream Object");

Draw & Print QR Code barcodes to Graphics object
qrcode.generateBarcodeToGraphics(".NET System.Drawing.Graphics Object");

Generate QR Code barcodes & write to byte[]
byte[] barcodeInBytes = qrcode.generateBarcodeToByteArray();

Generate QR Code barcodes & encode to System.Drawing.Bitmap object
Bitmap barcodeInBitmap = qrcode.generateBarcodeToBitmap();
*/
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
qrcode.generateBarcodeToImageFile("C://qrcode_4_vb.png")

hi all,

I found this when I was engaged in my project with barcode generating and reading.It provides C# and also VB.NET solution.And what impressed me most is that the provider of the library offers excellent service for an 100% free product.You can even request customized demo from their support forum.

regards

Hi, last year I did a project to create barcodes in C#. It's actually built for .NET, so it might support VB.NET as well. You can check out if this meets your requirements. 

that is can be found on this site,where you can see the barcode C# control,which i used for inserting code 39,and vb.net SDK library ,you may check it.

I used to work at a company which created an application that contains reading and writing barcodes. They used a commercial library for implementing reading and writing many types of barcode. I know they support C# and VB.NET.
