To use BarcodeWebControl in a web application created without Visual Studio, you need to do two things:

1. First, you need to copy the Bytescout.BarCode.dll file to the bin subdirectory of your web application's virtual directory as registered with IIS. If you don't have a separate web application, you can copy it to C:\Inetpub\wwwroot\bin.
2. Next, you do need to modify the Web.config file in your application's virtual directory (or C:\Inetpub\wwwroot\ if you don't have a separate application), by adding,

   	Copy Code
   <httpHandlers> <add verb="*" path="BarcodeHandler.aspx" type="Bytescout.BarCode.BarcodeHandler, Bytescout.BarCode"/> </httpHandlers>

   inside <system.web> section.

Note that there's no actual file called BarcodeHandler.aspx, but you can reference it within your application as a URL and you don't need to specify any path.

	Copy Code
<img src="BarcodeHandler.aspx?symbology=Code128&value=DATA" />

For a full list of parameter names see the table below.

To use BarcodeWebControl in a web application created within Visual Studio, you need:

1. Add new web.config file if you don't have one.
2. Set up an HttpHandler in an ASP.NET web application by adding <httpHandler> section as written above.
3. Dag and drop BarcodeWebImage from toolbox to your web page. This will add the references to Bytescout.BarCode.dll to your project. You can fine tune added control appearance by means of Windows Forms designer.

Below is a table of BarcodeHandler.aspx parameters:
