Delphi Cookbook - Second Edition

By: Daniele Teti

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, and Apple iOS. It helps you to concentrate on the real business and save yourself the pain of wandering amid GUI widget details, or having to tackle inter-platform incompatibilities. It also has a wide range of drag-and-drop controls, helping you code your business logic into your business model, and it compiles natively for desktop and mobile platforms. This book will teach you how to design and develop applications, deploy them on the cloud platform, and distribute them within an organization via Google Play and other similar platforms. You will begin with the basics of Delphi and get acquainted with JSON format strings, XSLT transformations, unicode encodings and various types of streams. We then move on to more advanced topics such as developing higher-order functions and using enumerators and RTTI. You will get an understanding of how Delphi RTL functions and how to use FireMonkey in a VCL application. We will then cover topics such as multithreading, using the parallel programming library and putting Delphi on a server. We will also take a look at the new feature of WebBroker Apache modules and then ride the mobile revolution with FireMonkey. By the end of the book, you will be able to develop and deploy cross-platform applications using Delphi .

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 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 jump on to more specific stuff when (and if) you require them.
