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" />
