MORE INFORMATION
The user is guided through the steps of a task when an application displays
a sequence of instructions using training card help. A training card
typically consists of text that explains a particular step and authorable
buttons associated with TCard macros that allow the user to tell the
application what to do next.
The training card instance of Windows Help is initiated by an application
calling the WinHelp function and specifying the HELP_TCARD command in
combination with another command such as HELP_CONTEXT. Subsequently, when
the user clicks an authorable button in the training card, clicks a hot
spot assigned to the TCard macro, or closes the training card, Windows Help
notifies the application by sending it a WM_TCARD message.
