This book is a continuation of the author's previous book, "Delphi. Just practice." Just like in "Delphi. Just Practice", this publication covers in detail programs for networks, various comic programs, simple toys, some useful applications, and application development in the Windows XP style. In particular, here you can find examples such as free SMS sending, FTP client, simple encryption, CGI scripts and much more. Describes methods for working with the Windows registry and INI files, as well as some important aspects of system-level programming using Windows API functions. To make programs easier to understand, each example contains comments on complex lines of code. The book is aimed at both those who already have experience creating applications in Delphi and novice programmers. For beginner Delphi users, an appendix describing the syntax of the Object Pascal programming language has been added at the end of the book.
