We have been using the Delphi programming language and integrated development environment for over 20 years. Before that, we used Pascal and Turbo Pascal. While we currently use several client-side and server-side development environments to power PhysiologyWeb, our favorite Windows development environment continues to be Delphi. Over the years, friends and users of PhysiologyWeb have asked us to share code with them. Therefore, we decided to share some of the codes we believe are useful and also are not so easy to find online. We hope these will be useful to you. If you find errors, encounter unhandled errors/exceptions, or have suggestions, please let us know.
