Fearless Cross-Platform Development with Delphi

By: David Cornelius

Overview of this book

Delphi is a strongly typed, event-driven programming language with a rich ecosystem of frameworks and support tools. It comes with an extensive set of web and database libraries for rapid application development on desktop, mobile, and internet-enabled devices. This book will help you keep up with the latest IDE features and provide a sound foundation of project management and recent language enhancements to take your productivity to the next level. You’ll discover how simple it is to support popular mobile device features such as sensors, cameras, and GPS. The book will help you feel comfortable working with FireMonkey and styles and incorporating 3D user interfaces in new ways. As you advance, you’ll be able to build cross-platform solutions that not only look native but also take advantage of a wide array of device capabilities. You’ll also learn how to use embedded databases, such as SQLite and InterBase ToGo, synchronizing them with your own custom backend servers or modules using the powerful RAD Server engine. The book concludes by sharing tips for testing and deploying your end-to-end application suite for a smooth user experience. By the end of this book, you’ll be able to deliver modern enterprise applications using Delphi confidently.

Providing remote server connectivity for clients

Our console app isn't really a true server yet because it has a user interface (albeit a crude one) that accepts input and displays output and then exits—no client app interacts with it. Our next step, then, is to replace the Readln and Writeln statements in the body of the main program loop, which waits for a human to type something into the console, with a way to start a listening and response mechanism that can be used by a client app.

Copy the data module (both the .pas and .dfm files) into a new folder and create a new app with it added; call this new app MyParksTCPServerConsole.

There are many ways for server and client applications to talk to one another. We discussed how Bluetooth was used in the previous chapter, which works when two devices are close together. In this chapter, we will use a very common method of communication used across the internet, which works anywhere a network connection is available...
