VB.NET ISSN Generator Data Encoding Tutorial

sample source code to input valid data and generate linear ISSN images in VB.NET

VB.NET ISSN Barcode Encoder is a quality linear barcode encoding SDK built for VB.NET developers who need integrating the ISSN barcode printing into their .NET projects. It supports the .NET 2.0, 3.0, 3.5, 4.0. The VB.NET ISSN Barcode Generator is capable of encoding ISSN barcode symbologies in ASP.NET Web projects, .NET WinForms apps as well as .NET reporting services (SSRS) projects using the Visual Basic .NET. It is simple to encode valid digits into the ISSN barcode symbology by Visual Basic .NET.

ISSN Valid Character Set

The ISSN, also known as International Standard Serial Number, is the acronym of International Standard Serial Numbering, which is used to mark serial publications like magazines, newspapers, or electronic periodical publications, etc.

An ISSN barcode is a fixed length barcode with 8-digit encoded. The first seven digits are the real ISSN number, and the last digit is the check digit calculated by Modulo 11. The ISSN barcode only encodes numeric characters from 0 through 9:

ISSN Character Set: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Encode data into ISSN using VB.NET

Sample for encoding data into ISSN with VB.NET

Dim barcode As Linear = New Linear

barcode.Type = BarcodeType.ISSN

barcode.Data = "123456789"

barcode.UOM = UnitOfMeasure.PIXEL

barcode.X = 2

barcode.Y = 70

barcode.LeftMargin = 2

barcode.RightMargin = 2

barcode.TopMargin = 2

barcode.BottomMargin = 2

barcode.Resolution = 100

barcode.Rotate = Rotate.Rotate0

ISSN Barcode Symbol Components

The above sample vb.net code displays the way of encoding data into an ISSN barcodes. After the numeric string "123456789" being encoded into the ISSN barcode images, it exports the following ISSN symbol:



The "ISSN 1234-5679" is the title for ISSN barcode symbology. In the ISSN barcode image, the number "1234567" is the real ISSN number, and the last digit "9" is the check digit. The digits, displayed under the ISSN symbol in the above image, include the following information from the left to the right:

1. Publication type, the first three digits "977" in the above ISSN image.

2. ISSN number, the fourth digit to the tenth digit "1234567" in the above

3. Edition variant, the numeric "89" in the above ISSN image

4. Checksum digit (Modulo 11), the "8" in the barcode symbol.
