Visual Solutions Pack / RAD Pack

Has anyone used the Formula One spreadsheet control that comes with
these packs ?

I am having no luck with Borland / Visual Tools - Both say it is not
down to them to support the product and basically wash their hands of
it.

What I need is to know how to use the external DLL calls.  The
reference manual is geared towards VB - very little mention of
Delphi.  Does anyone have a set of declarations for this control or a
sample program demonstrating the use of the external calls ?

Any help greatly appreciated
