The UCC/EAN-128 Symbology is a
subset of the more general Code 128 Symbology.
UCC/EAN-128 was developed to provide a worldwide format and standard for exchanging
common data between companies. While other bar codes simply encode data with no respect for
what the data represents, UCC/EAN-128 encodes data and encodes what that data represents.
UCC/EAN-128 has a list of Application Identifiers (AI). The
Application Identifier is a 2, 3, or 4-digit number that identifies the type of
data which follows. By convention, the Application Identifier is enclosed in
parentheses when printed below the barcode (the parentheses are only for visual
clarity, and are not encoded in the barcode).
Sample of a UCC/EAN-128 Barcode
How to encode UCC/EAN-128 values using Barcode Library
Introduction
UCC/EAN 128 encodes the so called Element Strings which are composed of an Application Identifier (AI)
plus a data field.
Each AI identifies the meaning and format of the data following it.
Note that the AI has parentheses around it in the human readable text,
but the parentheses are not encoded in the barcode.
Encode AI Code
In Barcode Library, developer mush put AI(dddd) around AI code, for the above sample image, you must
set Data property = 'AI(21)d12345777AI(21)12345678'.
In Barcode Library, you can use CH(ddd) format to encode ASCII data, for example CH(100) = d.
So for the above sample image, you can also
set Data property = 'AI(21)CH(100)12345777AI(21)12345678'.
Copy folder barcode from your downloaded package, to your IIS folder, e.g. C:\Inetpub.
Create a new virtual directory, named barcode.
Restart IIS.
Test your installation, goto http://YourDomain:port/barcode/linear.aspx?Type=EAN128&Data=12345678
To create barcode image in your ASP.NET application, you can pass the url to IMG tag src value.
For example, <img src="http://YourDomain:port/barcode/linear.aspx?Type=EAN128&Data=12345678" />
Add Reference BarcodeLib.Barcode.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.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.
Check component LinearWinForm, and its namespace is BarcodeLib.Barcode.Linear
If no component found, click Browse... button and select BarcodeLib.Barcode.dll file.
Now you can see the component displayed on Toolbox. You can drag LinearWinForm on your form, change barcode setting through properties widnow.
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.// save barcode image into your system
barcode.drawBarcode("c:/barcode.gif");
Above code written in C# 2005
* Please set properties UOB and Resolution, before you set any image size related properties like barWidth, margin.
Set the Data property with the value to encode. Type is string.
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.
Set the Format property for barcode image type. Value can be "gif", "jpg", "png", and "bmp", default is "png".
Set BearerBars property, if you want to draw borders around barcode image. Value can be BearerBar.None (no bear bars), BearerBar.Frame (top, bottom, left, right borders drawn), BearerBar.TopBottom (only top, bottom's are drawn).
Set Rotate property, if you want to rotate barcode image.
Value can be 0 (RotateOrientation.BottomFacingDown),
1 (RotateOrientation.BottomFacingLeft),
2 (RotateOrientation.BottomFacingUp),
3 (RotateOrientation.BottomFacingRight)
