When an accessibility client (such as a screen reader) requires help
information from a Control, it raises the
QueryAccessibilityHelp event, to allow you to
provide custom help information. This class encapsulates the data for
this event.
You should set the HelpNamespace (the URI of the
help file), the HelpKeyword (the topic ID within
that file, as a string), and the HelpString (the
What's This? help information) for the control on
which help is requested.
