HH_DISPLAY_TOPIC command

Opens a help topic in a specified help window.

If a window type is not specified, a default window type is used. If the window type or default window type is open, the help topic replaces the current topic in the window.

Specifies a compiled help (.chm) file, or a specific topic within a compiled help file. To specify a defined window type, insert a greater-than (>) character followed by the name of the window type.	Specifies NULL or a pointer to a topic within a compiled help file.

Example

HWND hwnd =

   HtmlHelp(

             GetDesktopWindow(),

             "c:\\help.chm::/intro.htm>mainwin",

             HH_DISPLAY_TOPIC,

             NULL) ;

Return value

The handle (hwnd) of the help window.

Comments

• For backward compatibility with WinHelp(), HH_DISPLAY_TOPIC and HH_HELP_FINDER provide the same functionality.
• A default help window contains only the Topic pane and is not a three-pane Help Viewer.
