Please add a HelpProvider to your form and try something like the following code:

private const string sHTMLHelpFileName_ShowWithNavigationPane = "CHM-example_ShowWithNavigationPane.chm";    
private void btnHelpTopic2_Click(object sender, EventArgs e)
{
helpProvider1.HelpNamespace = Application.StartupPath + @"\" + sHTMLHelpFileName_ShowWithNavigationPane;
Help.ShowHelp(this, helpProvider1.HelpNamespace, @"start.htm");
}

The help CHM help file was added to the project in a subfolder e.g. \hlp. For download I provide a C# VS2008 Project including the code above and the help files with different help viewer windows (different CHM files for show case only).

Please think of #_Toc417986991 as a internal bookmark generated by CHM Processor Software.
