GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.

 

.NET EAN 128/GS1 128 Generator supports:

• all 128 characters of ASCII
• values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

 

In C#

        Linear barcode = new Linear();
        barcode.Type = BarcodeType.CODE39;
        barcode.Data = "0123456789";
        barcode.drawBarcode("C://code39.gif");

In VB.NET

        Dim barcode As OnBarcode.Barcode.Linear
        barcode = New OnBarcode.Barcode.Linear()
        barcode.Type = OnBarcode.Barcode.BarcodeType.CODE39
        barcode.Data = "0123456789"
        barcode.drawBarcode("C://code39-in-vbnet.gif")

 

• 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=4
  
  
• To create barcode 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=4" />
  
  

 

In C#

        Linear barcode = new Linear();
        barcode.Type = BarcodeType.CODE39;
        barcode.Data = "0123456789";
        barcode.drawBarcode("C://code39.gif");

In VB.NET

        Dim barcode As OnBarcode.Barcode.Linear
        barcode = New OnBarcode.Barcode.Linear()
        barcode.Type = OnBarcode.Barcode.BarcodeType.CODE39
        barcode.Data = "0123456789"
        barcode.drawBarcode("C://code39-in-vbnet.gif")

 

Using C#, please call one of the following methods to draw barcode in the memory

        public void drawBarcode(Graphics graphics);

        public void drawBarcode(string filename);

        public Bitmap drawBarcode();

        public void drawBarcode(Stream fileStream);

Using VB.NET, please call one of the following methods to draw barcode in the memory

        Public Sub drawBarcode(ByRef graphics As Graphics)

        Public Sub drawBarcode(ByVal filename As String)

        Public Function drawBarcode() As Bitmap

        Public Sub drawBarcode(ByRef fileStream As Stream)
