Generating Barcode Codabar in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing Codabar and 30+ other linear & 2D bar codes for C#, VB.NET & ASP.NET applications.

OnBarcode develops several .NET Barcode Generation components for different .NET development environments:

Barcode Generation in ASP.NET - Creating barcodes in ASP.NET Web applications
Barcode Generation in Windows Forms - Printing barcodes in C#, VB.NET Windows Forms applications
Barcode Generation in Reporting Service - Drawing barcodes in Microsoft Reporting Service 2005 & 2008

 

Barcode Codabar Introduction

Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It is also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.

 

.NET Codabar Generation - Codabar Valid Data Scope

.NET Codabar Generator encodes 16 letters:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
• - (Dash), $ (Dollar), : (Colon), / (Slash), . (Point), + (Plus)

 

Generating barcode Codabar in C# Class example

	        Linear codabar = new Linear();
	        codabar.Type = BarcodeType.CODABAR;
	        codabar.Data = "0123456789";
	        codabar.X = 1;
	        codabar.Y = 60;
	        
	        // Generate Codabar and encode barcode to gif format
	        codabar.Format = ImageFormat.Gif;
	        codabar.drawBarcode("c#-codabar.gif");
	        
	        // Print Codabar to C# Bitmap object
	        Bitmap codabarBitmap = codabar.drawBarcode();

Generating barcode Codabar in VB.NET Class example

	        Dim codabar As OnBarcode.Barcode.Linear
	        codabar = New OnBarcode.Barcode.Linear()
	        codabar.Type = OnBarcode.Barcode.BarcodeType.CODABAR
	        codabar.Data = "0123456789"
	        codabar.X = 1
	        codabar.Y = 60
	        
	        // Generate Codabar and encode barcode to png format
	        codabar.Format = ImageFormat.Png
	        codabar.drawBarcode("vbnet-codabar.png")
	        
	        // Print Codabar to vb.net Bitmap object
	        Dim codabarBitmap As Bitmap
	        codabarBitmap = codabar.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=0
  
  
• To create barcode Codabar 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=0" />
  
  

 

Creating barcode Codabar in C# Class example

        Linear codabar = new Linear();
        codabar.Type = BarcodeType.CODABAR;
        codabar.Data = "0123456789";
        codabar.drawBarcode("C://barcode-codabar-csharp.gif");

Generating barcode Codabar in VB.NET Class example

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

 

To draw & print barcode Codabar to C# objects:

        public void drawBarcode(Graphics graphics);

        public void drawBarcode(string filename);

        public Bitmap drawBarcode();

        public void drawBarcode(Stream fileStream);

To draw & print barcode Codabar to VB.NET objects:

        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)

 

1. Add OnBarcode.Barcode.WinForms.dll to .net project reference
   
   
2. Add .NET Barcode to .NET Visual Studio Toolbox
   
   
   1. Right click .NET Visual Studio Toolbox, select menu Choose Items...
      
      
   2. In "Choose Toolbox Items" form, click button "Browse...", and select dll OnBarcode.Barcode.WinForms.dll
      
      
   3. After selection, you will find four items under "Components" section: LinearWinForm, DataMatrixWinForm, PDF417WinForm, and QRCodeWinForm.
