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.

Using SQLite databases to handle a to-do list

Usually, mobile apps read or write data using the network. In many cases, however, you need local storage to save your data. A local database can be useful for a number of things:

  • To save information that will be realigned on the central server when back at the office
  • To allow you a fast search on a relatively small set of data retrieved from a central database and stored on the device
  • To store some structured data

In all these cases, you have to handle a database. This recipe will show you how to do it.
