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.

Summary

At the beginning of this chapter, you learned the basic concept of tethering technology and how easy it is to implement in Delphi.

This chapter was done in stages; we first created the desktop application, which we called the server, although it is important to remember that in app tethering, there is no concept of a client and server, since all of the objects can be clients and servers at the same time.

We were able to connect Windows and Android clients automatically, thanks to the TTetheringManager group property. Using the same group and the same passwords, the AutoConnect() procedure could then be used without problems.

Note that there is a difference between creating a resources in TTetheringAppProfile of the type Shared and the type Mirror, with Shared always being the origin of the information, and Mirror being where we want the effect.

It is necessary for the...
