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 = "01234567899";
upca.X = 1;
upca.Y = 60;

// Generate UPC-A and encode barcode to gif format

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 = "01234567899"
upca.X = 1
upca.Y = 60

' Generate UPC-A and encode barcode to png format
upca.Format = System.Drawing.Imaging.ImageFormat.Png
upca.drawBarcode("C://vbnet-upca.png")

How to Create & Draw UPC-A Image in ASP.NET aspx or Html Pages Without ASP.NET Barcode Controller?
Top
  • 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" />
