.NET ITF-14 Barcode Introduction
ITF-14 is also known as UPC Shipping Container Symbol ITF-14, ITF14, Case Code, UPC Case Code, EAN/UCC-14, EAN-14, UCC-14, DUN-14, GTIN-14.
The ITF-14 or UPC Shipping Container Symbol is used to mark cartons, cases, or pallets that contain products which have a UPC or EAN product identification number. The short-hand name for the symbol is "ITF-14", which is an acronym for "Interleaved 2 of 5" (the Barcode Symbology used) and 14 digits (the length of the container symbol).
The ITF-14 symbol has the following structure:
1 digit for Packaging indicator
2 digits for UPC numbering system or EAN prefix
5 digits for Manufacturer identification number
5 digits for Item identification number
1 digit for Checksum which is automatically calculated by Java Barcode
The value to encode passed to Java Barcode must be 13 digits only because the 14th digit (the checksum) is automatically calculated by Java Barcode.

How to Generate ITF-14 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=18&Data=3011234500010
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=18&Data=3011234500010" /> Using this method, it will not generate any barcode images in your IIS server side.
How to Generate ITF-14 Barcode Image through ASP.NET Web Form Control?
Install .NET Barcode Controller to your ASP.NET project.
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.
Add barcode library to your Visual Studio Toolbox.
Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
Right click Toolbox, click menu Choose Items...
Goto .NET Framework Components tab.
If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.ASP.NET.dll file.
Then sort "Namespace" column, you will find 4 components from BarcodeLib.Barcode.
Check component LinearASPNET, and its namespace is BarcodeLib.Barcode.
Click "OK" button, you will find four components under "General": LinearASPNET.
Go to "barcode" folder in the trial package, copy file "linear.aspx" to the same folder as your aspx page, which will generate barcodes.
You can drag LinearASPNET on your aspx page in design view, change barcode setting through properties window.
Run the project, you will find barcode images generated in your aspx pages.
How to Generate ITF-14 Barcode Image through .NET Windows Form Control in C# or VB.NET?
Add Reference BarcodeLib.Barcode.WinFroms.dll to your project. Do not copy the dll to the bin directory, Visual Studio will do so, during project compilation time.
In your .NET windows project, right click mouse over Refereces in your Solution Explorer window. Then click menu "Add Reference ...".
Add BarcodeLib.Barcode.WinFroms.dll to your project.
Add barcode library to your Visual Studio Toolbox.
Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
Right click Toolbox, click menu Choose Items...
Goto .NET Framework Components tab.
If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.WinFroms.dll file.
Then sort "Namespace" column, you will find 4 components from BarcodeLib.Barcode.
Check component LinearWinForm, and its namespace is BarcodeLib.Barcode.
Click "OK" button, you will find the control under "Common Controls": LinearWinForm.
Now you can see the component displayed on Toolbox. You can drag LinearWinForm on your form, change barcode setting through properties widnow.
How to Generate ITF-14 Barcode Image in .NET class?
Add Reference BarcodeLib.Barcode.ASP.NET.dll or BarcodeLib.Barcode.WinFroms.dll to your .NET project (ASP.NET website, Forms, any .NET project). In your .NET class:
BarcodeLib.Barcode.Linear barcode = new BarcodeLib.Barcode.Linear(); barcode.Type = BarcodeType.ITF14;
// should be 13 digits barcode.Data = "3011234500001";
// generate barcode and output to Bitmap object Bitmap barcodeInBitmap = barcode.drawBarcode();
// generate barcode and output to HttpResponse object HttpResponse response = ...; barcode.drawBarcode(response);
// generate barcode and output to Stream object Stream stream = ...; barcode.drawBarcode(stream);
