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.

Introduction

Multithreading can be your biggest problem if you cannot handle it with care. One of the fathers of the Delphi compiler used to say:

"New programmers are drawn to multithreading like moths to a flame, with similar results."
– Danny Thorpe

In this chapter, we will discuss some of the main techniques to handle single or multiple background threads. We'll talk about shared resource synchronization and thread-safe queues and events. The last three recipes will talk about the Parallel Programming Library introduced in Delphi XE7, and I hope that you will love it as much as I love it. Multithreaded programming is a huge topic. So, after reading this chapter, although you will not become a master of it, you will surely be able to approach the concept of multithreaded programming with confidence, and will have the basics to move to more specific stuff...
