[quote="masonwheeler"]I read somewhere that Borland C++ Builder comes with the Delphi compiler included, allowing developers to use Object Pascal code in their C++ Builder projects. Does it work the other way too? If there's a library that's written in C++ that I'd like to use in my project, but I'd like to compile it directly into the executable and gain the benefits of smart-]

Afaik, yes, but only BCB in exactly the corresponding version (so not any C++ or even any BCB), and only when the C++ is specially crafted so that the interface doesn't use elements Delphi doesn't know (templates, operators maybe) and the classes are marked with the pureclass directive.

Which often for non trivial cases means: No. (since rework is too complicated and/or creates a separate codebase)

IIRC Rudy Velthuis homepage had some info on how to do this.
