I think the simple answer is that you can't use RTTI - have a look at
TypInfo.pas if you've got the source.
Interestingly, this was touched on in a recent EXE Online article
(http://www.exe.co.uk/articles/articlepull.asp?page=aug99/delphi.html).
But what can you find out with IDispatch: GetTypeInfo, GetTypeInfoCount,
GetIDsOfNames...?
