Applies to: ~>3.0
THelpContext = -MaxLongInt..MaxLongInt;
property HelpContext: THelpContext;
Set the HelpContext property to the context number of the relevant topic in the help file specified by the HelpFile property. When a non-zero help context number is specified a help button is displayed in the dialogue box which calls context sensitive help with the given help context when pressed.
If OnHelp is not handled and a help button is pressed, a request is made to the Application object to pass the help context along to the currently registered help system.
