make yourself a dll that either inherits a specific control, or inherits UserControl if it is a composite control.
upload the dll to your website
then in your html page
and that is it, minus security settings that may need to be set on the client including setting the website as a trusted site..Code:<object id="abutton" classid="http://yoursiteaddress/button.dll#namespace.classame">
<param name="Text" value="Test">
</object>
