Now that we have the User Control created, we have to compile it to a DLL. Use this syntax to create a DLL:

csc /t:library rtfcontrol.cs

The HTML page
Next we have to create the HTML page that the users will visit. Simple enough, all we have to add is an <object> tag at the location where we want the user control to appear. Here is a sample HTML page:

Código:

<html>
  <body>
   <center>
     <object id="rtfcontrol" height="472" width="488"
         classid="http://127.0.0.1/RtfControl.dll#devhood.rtfcontrol">
     </object>
   </center>
  </body>
</html>
