OpenHelp()

Syntax

OpenHelp(Filename$, Topic$)

Open and display a help window. The Filename$ parameter is the name of either the .chm or .hlp file to be opened. The Topic$ parameter is the internal name of the page to display, if the Topic$ parameter is not a NULL string (i.e. Topic$<>""), the OpenHelp function will display the specified page. This is very useful for online and/or contextual help.

Example:

  OpenHelp("help.chm", "index.htm")
  OpenHelp("help.chm", "print.txt")

On Microsoft Windows, there are two different help file formats which are supported: The ".hlp" format (which is the old) and the ".chm" format (which is the new).
