.NET Code 128 Generator - Barcode Code-128 Introduction

Code 128, also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, is a very high-density barcode symbology. (A special version of it called GS1-128 is used extensively world wide in shipping and packaging industries.) It is used for alphanumeric or numeric-only barcodes.

.NET Code 128 Generation - Code-128 Valid Data Scope

.NET Code 128 Generator encodes:
  • all 128 characters of ASCII
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.
How to Generate & Print Code-128 in Visual Studio C# or VB.NET Class?

Generating barcode Code-128 in C# Class example (C# Code 128 Generator Complete Demo Source Code):
   Linear code128 = new Linear();
code128.Type = BarcodeType.CODE128;
code128.Data = "0123456789";
code128.X = 1;
code128.Y = 60;

// Generate Code-128 and encode barcode to gif format
code128.Format = System.Drawing.Imaging.ImageFormat.Gif;
code128.drawBarcode("C://csharp-code128.gif");

// Print Code 128 C# Bitmap object
Bitmap code128Bitmap = code128.drawBarcode();
Generating barcode Code-128 in VB.NET Class example (VB.NET Code 128 Generator Complete Demo Source Code):

  • Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  • Restart IIS, navigate to http://YourDomain:Port/barcode/linear.aspx?DATA=CODE128&TYPE=7.
  • To create barcode Code 128 image in html or aspx pages, you can insert a image tag (img) into your page.
    For example, <img src="http://YourDomain:Port/barcode/linear.aspx?DATA=CODE128&TYPE=7" />
