This module exports the HTML Help structures and functions
from the hhctrl.ocx, distributed with MS HTML HELP Workshop.
The HTML Help application programming interface (API) enables a Windows
program to create a help window that displays a help topic.
The Windows program has complete control over the type, style,
and position of the help window.
The fundamental feature of the HTML Help API is the help window.
Through the API commands, you can create a help window that hosts
a Microsoft Internet Explorer DLL (Shdocvw.dll) and displays an HTML
file that you specify. The help window is owned by the window you specify.
As an owned window, a help window automatically stays on top of its
owner and closes when the owner is closed.
You define the styles, coordinates, captions, and display state of the
help window. This level of control allows you to embed the help window
in a non-OLE activated Windows program.
In addition to creating help windows, the HTML Help API commands also
enable you to provide:
Context-sensitive help.
Keyword lookups.
Interaction between a Windows program and a compiled help (.chm) file.
Control over the Navigation pane in the standard HTML Help Viewer.
