The same as he would do for any other COM object. There are tools in  
Delphi for building automatically the needed Delphi declarations  
(interfases, classes, methods, constants... similar to what makepy does  
for Python).
All OLE types work fine. (Variants are a bit hard to process, yes, but it  
can be done)

Sorry, I try to stay away of VB as far as possible :)
