Sample VB.NET Coding to Generate Barcode Images in ASP.NET Project

We use the example of VB.NET generation code to create Data Matrix in ASP.NET web. To create other barcode image, just change the barcode symbols accordingly and modify relevant barcode properties.

Dim DataMatrix As Terrek.Barcode.DotNET.DotNETControl = New Terrek.Barcode.DotNET.DotNETControl
DataMatrix.Symbol = Terrek.Barcode.BarcodeSymbol.DataMatrix
'Data Matrix valid character set, including standard ASCII and extended ASCII
DataMatrix.BarcodeData = "DataMatrix"
'Data Matrix data mode, including Auto, ASCII, C40, Text, X12, Edifact and Base256
DataMatrix.DataMatrixDataMode = Terrek.Barcode.DataMatrixDataMode.Auto
'Data Matrix format mode, ranging from 8*8 to 144*144
DataMatrix.FormatMode = Terrek.Barcode.DataMatrixFormatMode.Format_36X36
'Data Matrix resize and UOM setting
DataMatrix.ImageResize = True
DataMatrix.MeasuringUnit = Terrek.Barcode.MeasuringUnit.PIXEL
'Data Matrix use "~" to encode ACSII special character, set to true to encode those special characters
DataMatrix.Tilde = False
'Data Matrix structured append function, set true to apply structured append function
DataMatrix.StructuredAppend = False
'Data Matrix module width
DataMatrix.BarWidth = 2
'Data Matrix entire image width and height
DataMatrix.ImageWidth = 100
DataMatrix.ImageHeight = 100
' Data Matrix margin size of left, right, top and bottom
DataMatrix.MarginL = 6
DataMatrix.MarginR = 6
DataMatrix.MarginT = 6
DataMatrix.MarginB = 6
' Specify Data Matrix image
DataMatrix.DotsPerInch = 96
DataMatrix.Rotation = Terrek.Barcode.Rotation.Degree0
DataMatrix.BarcodeFormat = System.Drawing.Imaging.ImageFormat.Jpeg
DataMatrix.SaveAsImage("C:\DataMatrix.jpeg")
' Specify Data Matrix image color
DataMatrix.ImageColor = Color.White
DataMatrix.BarColor = Color.Black
