newbie question - making a COM client in BCB

This is the problem - I have some 3rd party DLL's which contain COM
objects with which I have to interface.
They provided a sample MFC program, but I've always liked BCB.

Frankly, the question is - where the heck do I start? Anyone know of
any sample BCB problems? My ignorence of this stuff is pretty total and
I need a handle to get me started.

thanks for any help,
