Back in 2000, there was a company called Quote.com that published a product called QFeed. Since I preferred Borland Delphi and they only had a C++ DLL or an OCX, I decided to write a Delphi binding.
QFeed has since been acquired by Linn Software Partners. You should visit the QFeed home page to see what they've done with it; I have no idea.
This is legacy code and almost certainly no longer works with the current QFeed product. It's here only because I hate to throw away what I consider good code, even if it is obsolete.
