Implement

1. When the barcode control dll is added to reference, you can programmatically input the Visual C# syntax for barcode printing. Here is a C# example for you, please copy to your project for a barcode printing test.

     Dim barcode As BarcodeLib.Barcode. Linear

     barcode = New BarcodeLib.Barcode. Linear()
     barcode.Type = BarcodeType.CODE39
     barcode.Data = "CODE39"
     barcode.UOM = BarcodeLib.Barcode.UnitOfMeasure.PIXEL
     barcode.Rotate = BarcodeLib.Barcode.RotateOrientation.BottomFacingDown

     barcode.BarWidth = 1
     barcode.BarHeight = 80

     barcode.LeftMargin = 5
     barcode.RightMargin = 5
     barcode.TopMargin = 5
     barcode.BottomMargin = 5
	
     ' Save barcode image into your system
     barcode.drawBarcode("c:/qrcode-vbnet.png")

     ' Generate barcode output to byte array
     byte[] barcodeInBytes = barcode.drawBarcodeAsBytes()

     ' Generate barcode to Graphics object
     Graphics graphics = ...
     barcode.drawBarcode(Graphics)

     ' Generate barcode and output to HttpResponse object
     HttpResponse response = ...
     barcode.drawBarcode(response) 

     ' Generate barcode and output to Stream object
     Stream stream = ...
     barcode.drawBarcode(stream)
