Delphi Cookbook - Third Edition

By: 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.

Converting a console application into a Windows service

Writing and debugging a Windows service can be difficult and slow. In the Creating a Windows service recipe in Chapter 1, Delphi Basics, you learned how to do it from scratch, but in some cases you already have a console or VCL application that already does its job, but it would be much better if it could be recreated as a Windows service.

Getting ready

In this recipe, we'll take the WebBroker application created in the previous recipe as a console application, and convert it to a fully flagged Windows service. The same approach can be used for any type of service-like application that is not currently built as a service.

As a bonus, we'll learn that, if correctly...
