Delphi Programming Projects

Overview of this book

Delphi is a cross-platform programming language and software development kit that supports rapid application development for Microsoft Windows, Apple Mac OS X, Android, and iOS. With the help of seven practical projects, this book will guide you through the best practices, Delphi Run-Time Library (RTL) resources, and design patterns. Whether you use the Visual Component Library (VCL) or FireMonkey (FMX) framework, these design patterns will be implemented in the same way in Delphi, using Object Pascal. In the first few chapters, you will explore advanced features that will help you build rich applications using the same code base for both mobile and desktop projects. In addition to this, you’ll learn how to implement microservice architecture in Delphi. As you get familiar with the various aspects of Delphi, you will no longer need to maintain source code for similar projects, program business rules on screens, or fill your forms with data access components. By the end of this book, you will have gained an understanding of the principles of clean code and become proficient in building robust and scalable applications in Delphi.

Creating app tethering applications

In an increasingly competitive world, having a positive differential puts us ahead. Imagine being able to extend your desktop applications and control them remotely. It may be possible, for example, to develop an application that advances the slides of a PowerPoint presentation to you on your phone, without the need for any specific hardware.

If we think about it a little, extending an application leads us to building new solutions without the end customer wasting time (after all, time is money, oh yeah!).

Imagine a remote control; now, imagine your cell phone as a remote control for your notebook. We can think of some useful commands, as follows:

  • Computer, open the browser on site x.
  • Computer, turn off Windows sound.
  • Computer, turn off the monitor.
  • Computer, play a song.
  • Computer, send me the sales report from my store.
  • Computer, make a backup...
