.NET Code 128 Generator - Barcode Code-128 Introduction

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.

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 = ImageFormat.Gif;
	        code128.drawBarcode("c#-code128.gif");
	        
	        // Print Code-39 128 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)

	        Dim code128 As OnBarcode.Barcode.Linear
	        code128 = New OnBarcode.Barcode.Linear()
	        code128.Type = OnBarcode.Barcode.BarcodeType.CODE128
	        code128.Data = "0123456789"
	        code128.X = 1
	        code128.Y = 60
	        
	        // Generate Code-128 and encode barcode to png format
	        code128.Format = ImageFormat.Png
	        code128.drawBarcode("vbnet-code128.png")
	        
	        // Print Code-128 to vb.net Bitmap object
	        Dim code128Bitmap As Bitmap
	        code128Bitmap = code128.drawBarcode();

• 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=0123456789&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=0123456789&TYPE=7" />
  
  

Creating barcode Code-128 in C# Class example

	        code128.ShowText = true;
	        
	        // Create Code-128 and encode barcode to Jpeg format
	        code128.Format = ImageFormat.Jpeg;
	        code128.drawBarcode("C://csharp-code128.jpg");
