IExtendedHelpViewer.DisplayHelpByContext Method

Use Context ID to display topic.

Pascal
procedure DisplayHelpByContext(const ContextID: Integer; const HelpFileName: string);
C++
__fastcall DisplayHelpByContext(const int ContextID, const AnsiString HelpFileName);

The RTL Help System calls DisplayHelpByContext to have the Viewer handle a context-based Help request. ContextID is the topic's Context ID. HelpFileName is the name of the file containing the topic. Note that some Help engines require the file name to be fully qualified.
