Fearless Cross-Platform Development with Delphi

By: David Cornelius

Overview of this book

Delphi is a strongly typed, event-driven programming language with a rich ecosystem of frameworks and support tools. It comes with an extensive set of web and database libraries for rapid application development on desktop, mobile, and internet-enabled devices. This book will help you keep up with the latest IDE features and provide a sound foundation of project management and recent language enhancements to take your productivity to the next level. You’ll discover how simple it is to support popular mobile device features such as sensors, cameras, and GPS. The book will help you feel comfortable working with FireMonkey and styles and incorporating 3D user interfaces in new ways. As you advance, you’ll be able to build cross-platform solutions that not only look native but also take advantage of a wide array of device capabilities. You’ll also learn how to use embedded databases, such as SQLite and InterBase ToGo, synchronizing them with your own custom backend servers or modules using the powerful RAD Server engine. The book concludes by sharing tips for testing and deploying your end-to-end application suite for a smooth user experience. By the end of this book, you’ll be able to deliver modern enterprise applications using Delphi confidently.

In fact, it's pretty simple to get one up and running—just follow these steps to bring the data modules from our console app into a new service app:

  1. Create a new Windows Service application (navigate to File | New | Other from the menu, and then expand Delphi and Windows).
  2. Answer "Yes" to enable the Visual Component Library framework.
  3. Add the two data modules we created for the server: udmParksDB and udmTCPParksServer.
  4. Add the logging units of LoggerPro, LoggerPro.FileAppender, and uMyParksLogging (these are the same ones from the previous server project except for the console logging unit).
