When using a HTML help file, you will obviously want to be able to display certain pages or sections. This code shows you how to display a topic in the help file by specifying the filename

Public Sub HTMLShowTopic(strTopic As String)

  ' Force the Help window to load a specific topic.
  ' The Help window will synchronize the
  ' Contents display automatically
  htmlHelpTopic hwnd, SetHTMLHelpStrings(), HH_DISPLAY_TOPIC, strTopic

End Sub

To call it, use this code:

HTMLShowTopic "html est_topic_1.htm"
