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

	Dim barcode As QRCode = New QRCode
	
	' QRCode Barcode Basic Settings
	
	'   QRCode Valid data char set:
	'        numeric data (digits 0 - 9);  
	'        alphanumeric data (digits 0 - 9; upper case letters A -Z; nine other characters: space, $ % * + - . / : );
	'        byte data (default: ISO/IEC 8859-1);
	'        Kanji(characters)
	barcode.Data = "112233445566"
	
	barcode.DataMode = QRCodeDataMode.AlphaNumeric
	barcode.Version = QRCodeVersion.V1
	barcode.ECL = QRCodeECL.L
	
	'  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
	'       modified to FS, GS, RS and US respectively.
	'  2) 2-byte character (Unicode): ~6ddddd (character value from 00000 ~ 65535)
	'         Strings from "~665536" to "~699999" are unused
	'  3) for GS1 AI Code: 
	'         ~ai2: AI with 2 digits
	'         ~ai3: AI with 3 digits
	'         ~ai4: AI with 4 digits
	'         ~ai5: AI with 5 digits
	'         ~ai6: AI with 6 digits
	'         ~ai7: AI with 7 digits
	'  4) ECI: ~7dddddd (valid value of dddddd from 000000 to 999999)
	'  5) SJIS: from ~9ddddd (Shift JIS 0x8140 ~ 0x9FFC and 0xE040 ~ 0xEBBF)
	barcode.ProcessTilde = True
	
	' Barcode Size Related Settings
	barcode.UOM = UnitOfMeasure.PIXEL
	barcode.X = 3
	barcode.LeftMargin = 0
	barcode.RightMargin = 0
	barcode.TopMargin = 0
	barcode.BottomMargin = 0
	barcode.Resolution = 96
	barcode.Rotate = Rotate.Rotate0
	
	' Image format setting
	barcode.ImageFormat = Drawing.Imaging.ImageFormat.Gif()
	
	barcode.drawBarcode("c:/qr-code.gif")
