Description
Retrieves the Help context of a member of the ActiveX control.
Use GetHelpContext to retrieve the Help context of a member of the ActiveX control.
Member is the name of a property, method, or event of the ActiveX control. To retrieve the help context of the ActiveX control itself, set Member to nil (Delphi) or NULL (C++).
HelpCtx is a variable in which the Help context identifier of Member is to be stored.
HelpFile is a variable in which the name of the Help file containing HelpCtx is to be stored.
The information about the ActiveX control is retrieved from its ITypeInfo interfaces. For more information, search for ITypeInfo in the Microsoft Developer Network library.
GetHelpContext returns false if Member is not found; otherwise, GetHelpContext returns true.
