You can use HtmlHelp API function:

#define HH_DISPLAY_TOPIC 0
#define HH_HELP_CONTEXT 15

Declare integer HtmlHelp in "HHCtrl.ocx" As HtmlHelpI;
   integer hwndCaller, string pszFile, ;
   integer uCommand, integer dwData
Declare integer HtmlHelp in "HHCtrl.ocx" As HtmlHelpS;
   integer hwndCaller, string pszFile, ;
   integer uCommand, String dwData
Declare integer GetDesktopWindow in win32api

* display default topic
HtmlHelpI(GetDesktopWindow(), "MyHelp.chm", HH_DISPLAY_TOPIC, 0)
* display topic by file name
HtmlHelpS(GetDesktopWindow(), "MyHelp.chm", HH_DISPLAY_TOPIC, "page2.htm")
* display topic by context ID
HtmlHelpI(GetDesktopWindow(), "MyHelp.chm", HH_HELP_CONTEXT, ContextID)

KB article Q247241 contains a VFP sample for this function.
