HTMLHELP_DYNAMIC_LINK
When this directive is defined the HTML Help interface unit is compiled using explicit dynamic linking. See About Dynamic Linking for more information on what this encompasses. When HTMLHELP_DYNAMIC_LINK_EXPLICIT is not defined then the HTML Help library is automatically loaded in the modules initialization section and unloaded in the modules finalization section using LoadLibrary and FreeLibrary respectively. The function HtmlHelpLoaded is available to test whether the HTML Help library (hhctrl.ocx) was succesfully loaded.
