Thanks for suggestions,
It seems that this sample creats the .rtf format, what I am looking is to be able to display an HTML page that is an aggregate of several HTML documents that are dynamically contcatenated into a one page (as if it is some kind of a report). When user selects one of the buttons on a panel on the left, the panel on the right that hosts the HTML page should be able to scroll to the correct portion of the HTML report. It seems that I might be able to do this using the Browser ActiveX control.

Yeh that'll work, but you get a real heavy duty axWebBrowser control ..
kinda like killing a fly with a hammer .. but if you must use that .. here
is sample code to render a "text" to a webbrowser control -

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using mshtml;

namespace WindowsApplication2
{
       public class Form1 : System.Windows.Forms.Form
       {
               private AxSHDocVw.AxWebBrowser browser;
               private System.ComponentModel.Container components = null;

               public Form1()
               {
                       InitializeComponent();
                       string url = "about:blank";
                       object o = System.Reflection.Missing.Value;
                       browser.Navigate ( url,ref o,ref o,ref o,ref o);

AxSHDocVw.DWebBrowserEvents2_StatusTextChangeEventHandler handler =
                         new
AxSHDocVw.DWebBrowserEvents2_StatusTextChangeEventHandler
                         (this.browser_StatusTextChange);
                       browser.StatusTextChange += handler;
               }

               private void browser_StatusTextChange
                       (object sender,
AxSHDocVw.DWebBrowserEvents2_StatusTextChangeEvent e)
               {

                       mshtml.HTMLDocument doc =
(mshtml.HTMLDocument)this.browser.Document;
                       doc.body.innerHTML = "<H1>foo</H1>";
               }

               {
                       if( disposing )
                       {

                               {
                                       components.Dispose();
                               }
