I can't answer your direct question about the FB API. However, I would like to suggest that you take a look at IBPP, a really good C++ wrapper around the raw API (http://www.ibpp.org). It handles a lot of gruesome API details from you and makes database access much easier. There are also several good component sets for use within C++ Builder if you want a higher-level interface: you might check out the list available at http://www.ibphoenix.com/main.nfs?a=ibphoenix&page=ibp_dev_comps.
