Delphi Cookbook - Third Edition

By: Daniele Spinetti, Daniele Teti

Overview of this book

Delphi is a cross-platform integrated development environment (IDE) that supports rapid application development on different platforms, saving you the pain of wandering amid GUI widget details or having to tackle inter-platform incompatibilities. Delphi Cookbook begins with the basics of Delphi and gets you acquainted with JSON format strings, XSLT transformations, Unicode encodings, and various types of streams. You’ll then move on to more advanced topics such as developing higher-order functions and using enumerators and run-time type information (RTTI). As you make your way through the chapters, you’ll understand Delphi RTL functions, use FireMonkey in a VCL application, and cover topics such as multithreading, using aparallel programming library and deploying Delphi on a server. You’ll take a look at the new feature of WebBroker Apache modules, join the mobile revolution with FireMonkey, and learn to build data-driven mobile user interfaces using the FireDAC database access framework. This book will also show you how to integrate your apps with Internet of Things (IoT). By the end of the book, you will have become proficient in Delphi by exploring its different aspects such as building cross-platforms and mobile applications, designing server-side programs, and integrating these programs with IoT.

Using app tethering to create a companion app

App tethering is one of the main features introduced in RAD Studio XE6 and since then it has been improved in security and functionality. App tethering allows you to connect applications to exchange in a so-called serverless mode. In other words, it gives your applications the ability to interact with other applications running either on the same machine or on a remote machine without using a server because the applications communicate directly with each other.

App tethering features do not depend on a specific transport or protocol, and new protocols can be implemented using the app tethering API. Currently, app tethering can work using a network or Bluetooth Classic adapter using the same code.

To enable an application to use app tethering, only two components are required:

  • TTetheringManager: Used to discover other applications...
