1. Create a Windows form. Place the controls as shown in this video: http://sudipta.posterous.com/private/eweuvoFJwb. Eventually, your layout should look like the one shown in the preceding screenshot. As it is a complex layout, I have created the video to help you.
2. Add the following variables to
Form1.cs:bool startRecording = false;
This will be set to true when the app starts recording keystrokes.
3. Add the following field to the
Form1.cs:string alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; pianokeys, creatingDictionary<string, string> pianoNotes = new Dictionary<string, string>(); Dictionary<string, char> keySettings = new Dictionary<string, char>(); List<KeyValuePair<string, DateTime>> keyPressRecord = new List<KeyValuePair<string,DateTime>>();
4. Add the following methods:
/// <summary> /// Plays the .WAV file associated with the pressed key /// </summary...

Overview of this book
Generics were added as part of .NET Framework 2.0 in November 2005. Although similar to generics in Java, .NET generics do not apply type erasure but every object has unique representation at run-time. There is no performance hit from runtime casts and boxing conversions, which are normally expensive..NET offers type-safe versions of every classical data structure and some hybrid ones.
This book will show you everything you need to start writing type-safe applications using generic data structures available in Generics API. You will also see how you can use several collections for each task you perform. This book is full of practical examples, interesting applications, and comparisons between Generics and more traditional approaches. Finally, each container is bench marked on the basis of performance for a given task, so you know which one to use and when.
This book first covers the fundamental concepts such as type safety, Generic Methods, and Generic Containers. As the book progresses, you will learn how to join several generic containers to achieve your goals and query them efficiently using Linq. There are short exercises in every chapter to boost your knowledge.
The book also teaches you some best practices, and several patterns that are commonly available in generic code.
Some important generic algorithm definitions are present in Power Collection (an API created by Wintellect Inc.) that are missing from .NET framework. This book shows you how to use such algorithms seamlessly with other generic containers.
The book also discusses C5 collections. Java Programmers will find themselves at home with this API. This is the closest to JCF. Some very interesting problems are solved using generic containers from .NET framework, C5, and PowerCollection Algorithms ñ a clone of Google Set and Gender Genie for example!
The author has also created a website (http://www.consulttoday.com/genguide) for the book where you can find many useful tools, code snippets, and, applications, which are not the part of code-download section
