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.

Creating Linux TCP/IP servers

Linux has always been a highly appreciated operating system, especially for the server-side. So what better start for development on Linux? Creating a small TCP/IP server.

Getting ready

In this recipe, we're going to create a TCP/IP server that listens on a port for incoming requests from a TCP client. These client requests can then be processed at the server, and a response can be sent back to the client.

The server we are going to build will listen for client commands. It will always return the reverse string of the command passed, unless you pass the quit command; in that case, it will disconnect the client.

This recipe is very simple, but it will be of great help in taking the first steps...
