Description

ISpecialWinHelpViewer supports Help requests that cannot be easily generalized, and should only be handled by the Microsoft Windows Help engine or a closely compatible application. 

ISpecialWinHelpViewer consists of a single method, CallWinHelp, which should pass the Help request to the Help engine with as little manipulation as possible. An application needs to provide only one Viewer that implements ISpecialWinHelpViewer. If more than one Viewer is registered that implements ISpecialWinHelpViewer, only the first Viewer ever receives calls to CallWinHelp.
