Creating Code-39 barcode in VB.NET class example:

	Dim barcode As Linear = New Linear
	
	' Code 39 Barcode Basic Settings
	barcode.Type = BarcodeType.CODE39
	
	'   Code39 Valid data char set:
	'        0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Digits)
	'        A - Z (Uppercase letters)
	'        - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus) 
	
	'   Code39 extension Valid data char set:
	'        All ASCII 128 characters
	' Code39 encodes upper case chars only, for lower case chars, use Code 39 extension
	barcode.Data = "ONBARCODE"
	
	barcode.AddCheckSum = True
	
	'  Set the ProcessTilde property to true, if you want use the tilde character "~" 
	'  to specify special characters in the input data. Default is false.
	'
	'  1) 1-byte character: ~0dd/~1dd/~2dd (character value from 000 ~ 255); ASCII character '~' is presented by ~126
	'         Strings from "~256" to "~299" are unused
	barcode.ProcessTilde = False
	
	' Code 39 Wide Narrow bar Ratio
	' Valid value is from 2.0 to 3.0 inclusive.
	barcode.N = 3.0F
	' The space between 2 characters in code 39; This a multiple of X; The default is 1.;
	' Valid value is from 1.0 (inclusive) to 5.3 (exclusive)
	barcode.I = 1.0F
	barcode.ShowStartStopInText = False
	
	' Barcode Size Related Settings
	barcode.UOM = UnitOfMeasure.PIXEL
	barcode.X = 1
	barcode.Y = 80
	barcode.LeftMargin = 0
	barcode.RightMargin = 0
	barcode.TopMargin = 0
	barcode.BottomMargin = 0
	barcode.Resolution = 96
	barcode.Rotate = Rotate.Rotate0
	
	' Barcode Text Settings
	barcode.ShowText = True
	barcode.TextFont = New Drawing.Font("Arial", 9.0F, Drawing.FontStyle.Regular)
	barcode.TextMargin = 6
	
	' Image format setting
	barcode.Format = Drawing.Imaging.ImageFormat.Gif()
	
	barcode.drawBarcode("c:/code-39.gif")
