Delphi ContinuumClient API

Ross Hemingway

HHS Software

This API and component set is built to work with the QDP (QFeed) API. It allows Delphi (and BCB) programmers to link their apps directly to the ContinuumClient.dll, and make function calls like an MSVC program can. It includes Types and objects in pascal to cover all the original MSVC classes. All constants are defined too.

Your compiled app does not require any additional file (activex, etc.) and all 134 functions are covered. How it works is to link the CC.dll file directly (static). The API takes the function parameters, pushes them onto stack or registers in the same manner as the MSVC++ standard. Then awaits the return, and corrects the return value for any type differences in the languages. Sinks are done by making a replica of the MSVC++ class and passing it to the CC.dll. In short we use assembler to trick the CC.dll into thinking it's talking with one of its own kind.

You get all source codes, a demo app commented throughout, various extra help files. Note: requires Delphi 4 or higher - can be imported into BCB as well.
