Add reference and namespaces

First you have to add reference to Barcode.dll to your project. See MSDN how to. Then add all namespaces you need:

Copy
// C#

using Limilabs.Barcode;
using System.Drawing.Imaging;
Render barcode

Copy
// C#

using Limilabs.Barcode;
using System.Drawing.Imaging;

BaseBarcode barcode = BarcodeFactory.GetBarcode(Symbology.EAN13);

barcode.Number = "123456789012";
barcode.ChecksumAdd = true;

// Render barcode:
this.pictureBox1.Image = barcode.Render();

// You can also save it to file:
barcode.Save("c:\\barcode.gif", ImageFormat.Gif);
ASP.NET control

  1. Create new ASP.NET project

  2. Add new web.config file if you don't have one.

  3. Set up an HttpHandler in an ASP.NET web application, add the following code to your web.config file:

    • Register an HTTP handler for IIS 6.0:

      Copy
      <configuration>
  <system.web>
    <httpHandlers>
      <add verb="*" path="Barcode.axd"
        type="Limilabs.Web.BarcodeHttpHandler" />
    </httpHandlers>
  </system.web>
</configuration>

    • Register an HTTP handler for IIS 7.0 and IIS 8.0 running in Integrated Mode:

      Copy
      <configuration>
  <system.webServer>
    <handlers>
      <add name="BarcodeHttpHandler" verb="*"
        path="Barcode.axd"
        type="Limilabs.Web.BarcodeHttpHandler, Barcode"
        resourceType="Unspecified" />
    </handlers>
  </system.webServer>
</configuration>

    • Register an HTTP handler for IIS 7.0 and IIS 8.0 running in Classic mode:

      Copy
      <configuration>
  <system.web>
    <httpHandlers>
      <add verb="*" path="Barcode.axd" type="Limilabs.Web.BarcodeHttpHandler, Barcode" />
    </httpHandlers>
  </system.web>
  <system.webServer>
    <add name="BarcodeHttpHandler" verb="*"
      path="Barcode.axd"
      Modules="IsapiModule"
      scriptProcessor="FrameworkPath\aspnet_isapi.dll"
      resourceType="File" />
  </system.webServer>
</configuration>

      ...remember to replace FrameworkPath with the correct path to the Aspnet_isapi.dll file.

    • If you are using VS2003 use the following:

      Copy
      <httpHandlers>
    <add
      verb="*"
      path="Barcode.axd"
      type="Limilabs.Web.BarcodeHttpHandler, Barcode"  />
</httpHandlers>
