Using Training Card Help
Training cards provide a more interactive approach to the Windows help system and help the user perform complex tasks by leading them through the process. An application initiates training card help by combining the HELP_TCARD flag with another command in a call to WinHelp. Windows Help will display the requested topic, which normally will contain one or more authorable buttons that the user can select. When the user selects one of these buttons, or carries out some other action, Windows help sends a WM_TCARD message to the application, indicating the user's action. See the example under the WM_TCARD message later in this chapter for an example of an application using training card help.
