Generating barcode UPC-A in C# Class example (C# UPC-A Generator Complete Demo Source Code)

	        Linear upca = new Linear();
	        upca.Type = BarcodeType.UPCA;
	        upca.Data = "12345678912";
	        upca.X = 1;
	        upca.Y = 60;
	        
	        // Generate UPC-A and encode barcode to gif format
	        upca.Format = ImageFormat.Gif;
	        upca.drawBarcode("c#-upca.gif");
	        
	        // Print UPC-A to C# Bitmap object
	        Bitmap upcaBitmap = upca.drawBarcode();

Generating barcode UPC-A in VB.NET Class example (VB.NET UPC-A Generator Complete Demo Source Code)

	         Dim upca As OnBarcode.Barcode.Linear
	        upca = New OnBarcode.Barcode.Linear()
	        upca.Type = OnBarcode.Barcode.BarcodeType.UPCA
	        upca.Data = "12345678912"
	        upca.X = 1
	        upca.Y = 60
	        
	        // Generate UPC-A and encode barcode to png format
	        upca.Format = ImageFormat.Png
	        upca.drawBarcode("vbnet-upca.png")
	        
	        // Print UPC-A to vb.net Bitmap object
	        Dim upcaBitmap As Bitmap
	        upcaBitmap = upca.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=12345678912&TYPE=36
  
  
• To create barcode UPC-A 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=12345678912&TYPE=36" />
  
  

Creating barcode UPC-A image in C# Class example

	        Linear upca = new Linear();
	        upca.Type = BarcodeType.UPCA;
	        upca.Data = "12345678912";
	        upca.X = 1;
	        upca.Y = 60;
	        
	        // Create UPC-A and encode barcode to Jpeg format
	        upca.Format = ImageFormat.Jpeg;
	        upca.drawBarcode("C://csharp-upca.jpg");

Creating barcode UPC-A image in VB.NET Class example

	        upca.X = 1
	        upca.Y = 60
	        
	        // Create UPC-A and encode barcode to Jpeg format
	        upca.Format = ImageFormat.Jpeg
	        upca.drawBarcode("C://vbnet-upca.jpg")

To draw & print barcode UPC-A 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 UPC-A 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)
