Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It was designed to be accurately read even when printed on dot-matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007.
This symbology is used by U.S. blood banks, photo labs, and on FedEx airbills. Because Codabar is self-checking, it does not define a check digit. This symbology starts and finishes with one of four possible characters A, B, C, or D.

Codabar Barcode for .NET, ASP.NET supports 16 letters.

1. Add Reference BarcodeLib.Barcode.dll to your .NET project (ASP.NET website, Forms, any .NET project)
   In your .NET class.
   

   BarcodeLib.Barcode.Linear.Linear barcode = BarcodeLib.Barcode.Linear.Linear();
   barcode.Data = "your barcode data";
   // other barcode settings.

* Please set properties UOB and Resolution, before you set any image size related properties like barWidth, margin.

In Windows Controller, just call method SaveAsImage(string filename). e.g. SaveAsImage("C:\barcode.gif");

• Set the Type property to BarcodeType.CODABAR
• Set the Data property with the value to encode. Type is string. Please do not include codabar start and stop chars in this property.
• Setting up barcode image size:
  • Set property UOM (Unit of Measure) for properties BarWidth, BarHeight, LeftMargin and TopMargin.
    Default is UnitOfMeasure.Pixel (0). Valid values are UnitOfMeasure.Pixel (0), UnitOfMeasure.CM (1), UnitOfMeasure.Inch (2).
  • Set the BarWidth (for bar cell width) and BarHeight (for bar cell height) properties. Both types are float.
  • Set the LeftMargin and TopMargin properties, and types are both float.
  • Set the Resolution property (Value is expressed in DPI - Dots per inch). This property is not working in Windows Controller, we will use end user's windows resultion.
• Setting up text style in barcode image:
  • Set the ShowText properties. If this value is true, barcode data will be displayed with the barcode.
  • Set the TextFont property. The font used to display text in barcode image.
