Generating barcode POSTNET in C# Class example (C# POSTNET Generator Complete Demo Source Code)

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

Generating barcode POSTNET in VB.NET Class example (VB.NET POSTNET Generator Complete Demo Source Code)

	        Dim postnet As OnBarcode.Barcode.Linear
	        postnet = New OnBarcode.Barcode.Linear()
	        postnet.Type = OnBarcode.Barcode.BarcodeType.POSTNET
	        postnet.Data = "0123456789"
	        postnet.X = 1
	        postnet.Y = 60
	        
	        // Generate Postnet and encode barcode to png format
	        postnet.Format = ImageFormat.Png
	        postnet.drawBarcode("vbnet-postnet.png")
	        
	        // Print Postnet to vb.net Bitmap object
	        Dim postnetBitmap As Bitmap
	        postnetBitmap = postnet.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=4
  
  
• To create barcode Postnet 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" />
  
  

Creating barcode Postnet in C# Class example

        Linear postnet = new Linear();
        postnet.Type = BarcodeType.POSTNET;
        postnet.Data = "0123456789";
        postnet.drawBarcode("C://postnet.gif");
