The Ruby Way takes a "How-To" approach to Ruby programming with the bulk of the material consisting of more than 400 examples arranged by topic. Each example answers the question "How do I do this in Ruby?" Working along with the author, you are presented with the task description and a discussion of the technical constraints. This is followed by a step-by-step presentation of one good solution. Along the way, the author provides detailed commentary and explanations to aid your understanding.
This sample is demostrating how to create an event in a DLL file and afterward how to call this event from a client program. Hope it can help you to understand the DLL event mechanism and CALLBACK term in VC++.
Object-oriented languages
define objects (types of things) that know how to perform methods (specific actions).
Functional languages treat programming problems like mathematical relationships.
Ruby is flexible, meaning that you can program in any of these styles however, it is
primarily object oriented, with some strong functional influence. This book focuses
slightly more on the functional aspects of Ruby than some other books.
