Postnet barcode. This symbology usually gets printed by U.S. Post Office on envelopes. Postnet symbology allows only numeric values to be encoded. The bar code itself can encode either a standard 5-digit Zip Code, a Zip+4 code, or a full 11-point delivery point code.
Important: you can also use BarCode Windows Forms or Web ImageControl instead. To use the Windows Formscontrol in Visual Studio please open Toolbox and open “Bytescout Software” tab and drag-n-drop “BarCode” control into your WinForms or ASP.NET application (in design mode)
Visual Basic:
Imports Bytescout.BarCode
Module Module1
Sub Main()
‘ Create new barcode
Dim barcode As New Barcode()
‘ Set symbology
barcode.Symbology = SymbologyType.Postnet
‘ Set value
barcode.Value = “12345123412”
‘ Save barcode to image
barcode.SaveImage(“result.png”)
‘ Show image in default image viewer
Process.Start(“result.png”)
End Sub
End Module
