.NET UPC-A Barcode Introduction
UPC-A is also known as Universal Product Code version A, UPC-A Supplement 5/Five-digit Add-On, UPC-A Supplement 2/Two-digit Add-On, UPC-A+5, UPC-A+2, UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12 .
The "UPC-A bar code" is by far the most common and well-known symbology, at least in the United States. An UPC-A bar code is the bar code you will find on virtually every consumer good on the shelves of your local supermarket, as well as books, magazines, and newspapers. It is commonly called simply a "UPC bar code" or "UPC Symbol." This isn't entirely accurate since there are a number of other UPC formats (UPC-E, UPC 2-Digit Supplement, UPC 5-Digit Supplement).
Sample of a UPC-A Barcode
The value to encode by UPC-A has the following structure:
1 digit for Number System (0: regular UPC codes, 1: reserved, 2: random weight items marked at the store, 3: National Drug Code and National Health Related Items code, 4: no format restrictions, for in-store use on non-food items, 5: for use on coupons, 6: reserved, 7: regular UPC codes, 8: reserved, 9: reserved)
5 digits for Manufacturer (Company) Code or prefix. This number is assigned by the Uniform Code Council (UCC)

1 digit for checksum
Add-On or Supplement code

How to Generate UPC-A Barcode Image in IIS without Visual Studio .NET?
Under downloaded trial package, copy barcode folder to your IIS folder, e.g. C:\Inetpub.
Create a new virtual directory in IIS, named barcode, and link to the above "barcode" folder.
Restart IIS.
To test your installation, open your web browser and navigate to: http://YourDomain:Port/barcode/linear.aspx?Type=28&Data=12345678901
To create barcode image in your aspx or html page, you need pass the url to IMG tag src value. For example: <img src="http://YourDomain:port/barcode/linear.aspx?Type=28&Data=12345678901" /> Using this method, it will not generate any barcode images in your IIS server side.
How to Generate UPC-A Barcode Image through ASP.NET Web Form Control?
Add Reference BarcodeLib.Barcode.ASP.NET.dll to your project. Do not copy the dll to the bin directory, Visual Studio will do so, during project compilation time.
