Here’s a cool site that has a lot of reference information for Delphi.
This web site provides help and reference for the fundamentals of the Delphi© language. It is gives an introduction to the Delphi Object Oriented Language for newcomers, and provides a ready reference for experienced programmers.
It limits itself to a broad base of the language in order to keep things simple and manageable. The approach taken is to present the most useable basics of Delphi in as accessible a manner as possible.
