Description

IExtendedHelpViewer extends ICustomHelpViewer by adding support for Topic IDs and Context IDs. 

A topic ID is a short string that uniquely identifies each topic provided by a Help Viewer. A topic ID provides a simple way for an application to display a specific Help topic without searching for it. 

A context ID is an integer value that uniquely identifies each Help topic. Context IDs support context-sensitive Help by providing a value that associates forms and controls with their help topics. A form or control can be associated a topic simply by setting its HelpContext property.
