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.
