HTMLHELP_DYNAMIC_LINK_EXPLICIT

When both HTMLHELP_DYNAMIC_LINK and HTMLHELP_DYNAMIC_LINK_EXPLICIT are defined the LoadHtmlHelp and UnloadHtmlHelp function are available to control precisely when the HTML Help library is loaded and unloaded. When HTMLHELP_DYNAMIC_LINK_EXPLICIT is defined the HTML Help library is not automatically loaded at module initialization, you'll have to call LoadHtmlHelp explicitly. UnloadHtmlHelp is still automatically called at module finalization but you can manually call it at any time to explicitly unload the HTML Help library. The HtmlHelpLoaded function can be used to test whether the HTML Help API was loaded succesfully. See About Dynamic Linking for more background information.
