Thank You very much Mr. Chandler,
 It has been very kind of you ... I'm sorry that I used your working email 
address to request Your help,
I'd already searched that site, I think it's a very good one even if they do 
not consider BCB :-( ... too much VC++ oriented :-( , but it's free and for 
a student that means so much :-) .. I did not consider that project, and the 
ones about OLE drag & drop used the MFC.
I'll try to implement TBasicEnumFORMATETC class.
Anyway I already found a good FREE component with SOURCE CODE at Delphi 
Super page http://bdn.borland.com/homepages/dsp/index.htm
exactly http://delphi.icm.edu.pl/ftp/d30free/dragdrop.exe  Copyright � 
1997-99 Angus Johnson & Anders Melander, of course it's written in delphi 
(why do our cousins always have all the components they need?) and it would 
take sometime to translate (for learning) but the component can be installed 
fine into BCB 6 too ...
It would be great to have such a component for BCB users too ( I mean 
something written in BCB from which to learn) so if my studies give me some 
rest I'll try to follow your way and create a basic BCB drag & drop 
component.
 Thank You so much again,
Beast regards,
Stefano B.
