This book is
targeted toward those who have little or no programming experience or who might
be picking up C# as a second language. The book has been structured and written
with a purpose: to get you productive as quickly as possible. I’ve used my
experiences in writing applications with C# and teaching C# to create a book
that I hope cuts through the fluff and teaches you what you need to know. All
too often, authors fall into the trap of focusing on the technology rather than
on the practical application of the technology. I’ve worked hard to keep this
book focused on teaching you practical skills that you can apply immediately
toward a development project.
This book is
divided into ten Chapters, each of which focuses on a different aspect of
developing applications with C#. These parts generally follow the flow of tasks
you’ll perform as you begin creating your own programs with C#. I recommend
that you read them in the order in which they appear.
this book develops the concepts and theory of Building the Program Logic and
Interfaces analysis, Exceptions, Delegates and Events and other important
things in a gradual, step-by-step manner, proceeding from concrete examples to
abstract principles. Standish covers a wide range of both traditional and
contemporary software engineering topics.

C# Programming is a solution bank for various complex problems related to C#
and .NET. It can be used as a reference manual by Computer Science Engineering
students. This Book also covers all aspects of B.TECH CS, IT, and BCA and MCA,
introduced programmers to a new era called functional programming. C# focused
on bridging the gap between programming languages and databases. This book
covers all the language features from the first version through C# . It also
provides you with the essentials of using Visual Studio 2005 to let you enjoy
its capabilities and save you time by using features such as IntelliSense.
new programming language can be intimidating. If you’ve never programmed
before, the act of typing seemingly cryptic text to produce sleek and powerful
applications probably seems like a black art, and you might wonder how you’ll
ever learn everything you need to know. The answer is, of course, one step at a
step to learning a language is the same as that of any other activity: building
confidence. Programming is part art and part science. Although it might seem
like magic, it’s more akin to illusion: After you know how things work a lot of
the mysticism goes away, freeing you to focus on the mechanics necessary to
produce any given desired result.

A working knowledge of Scala puts you in demand. As both the language and applications expand, so do the opportunities for experienced Scala programmers—and many positions are going unfilled. Twitter, Comcast, Netflix, and other major enterprises across industries are using Scala every day, in a number of different applications and capacities. Professional Scala helps you update your skills quickly to start advancing your career.
If you have done Java programming before and have a basic knowledge of Scala and its syntax, then this book is an ideal choice to help you to understand the context, the traditional design pattern applicable, and the Scala way. Having previous knowledge of design patterns will help, though it is not strictly necessary.What You Will LearnGet to know about functional programming and the value Scala's FP idioms bring to the tableSolve day-to-day programming problems using functional programming idiomsCut down the boiler-plate and express patterns simply and elegantly using Scala's concise syntaxTame system complexity by reducing the moving partsWrite easier to reason about concurrent code using the actor paradigm and the Akka libraryApply recursive thinking and understand how to create solutions without mutationReuse existing code to compose new behaviorCombine the object-oriented and functional programming approaches for effective programming using ScalaIn Detail
Scala is used to construct elegant class hierarchies for maximum code reuse and extensibility and to implement their behavior using higher-order functions. Its functional programming (FP) features are a boon to help you design “easy to reason about” systems to control the growing software complexities. Knowing how and where to apply the many Scala techniques is challenging. Looking at Scala best practices in the context of what you already know helps you grasp these concepts quickly, and helps you see where and why to use them.
This book begins with the rationale behind patterns to help you understand where and why each pattern is applied. You will discover what tail recursion brings to your table and will get an understanding of how to create solutions without mutations. We then explain the concept of memorization and infinite sequences for on-demand computation. Further, the book takes you through Scala's stackable traits and dependency injection, a popular technique to produce loosely-coupled software systems.
You will also explore how to currying favors to your code and how to simplify it by de-construction via pattern matching. We also show you how to do pipeline transformations using higher order functions such as the pipes and filters pattern. Then we guide you through the increasing importance of concurrent programming and the pitfalls of traditional code concurrency. Lastly, the book takes a paradigm shift to show you the different techniques that functional programming brings to your plate.
This book is an invaluable source to help you understand and perform functional programming and solve common programming problems using Scala's programming patterns.Style and approach

Based on the latest research in cognitive science and learning theory, Head First Ruby uses a visually rich format to engage your mind, rather than a text-heavy approach to put you to sleep. Why waste your time struggling with new concepts? This multi-sensory learning experience is designed for the way your brain really works.
The result is software that is truly object-oriented: not code that is partially object-oriented, with a large database-shaped lump on the back end. JDO lets you save plain, ordinary Java objects, and does not force you to use different data models and types for dealing with storage. As a result, your code becomes easier to maintain, easier to re-use, and easier to test. And you're not tied to a specific database vendor: your JDO code is entirely database-independent. You don't even need to know whether the datastore is a relational database, an object database, or just a set of files.
This book, written by the JDO Specification Lead and one of the key contributors to the JDO Specification, is the definitive work on the JDO API. It gives you a thorough introduction to JDO, starting with a simple application that demonstrates many of JDO's capabilities. It shows you how to make classes persistent, how JDO maps persistent classes to the database, how to configure JDO at runtime, how to perform transactions, and how to make queries. More advanced chapters cover optional features such as nontransactional access and optimistic transactions. The book concludes by discussing the use of JDO in web applications and J2EE environments.
Whether you only want to read up on an interesting new technology, or are seriously considering an alternative to JDBC or EJB CMP, you'll find that this book is essential. It provides by far the most authoritative and complete coverage available.

Scripting languages are becoming increasingly important for software development. These higher-level languages, with their built-in easy-to-use data structures are convenient for programmers to use as "glue" languages for assembling multi-language applications and for quick prototyping of software architectures. Scripting languages are also used extensively in Web-based applications. Based on the same overall philosophy that made Programming with Objects such a wide success, Scripting with Objects takes a novel dual-language approach to learning advanced scripting with Perl and Python, the dominant languages of the genre. This method of comparing basic syntax and writing application-level scripts is designed to give readers a more comprehensive and expansive perspective on the subject.
Beginning with an overview of the importance of scripting languages—and how they differ from mainstream systems programming languages—the book explores:
Regular expressions for string processing
The notion of a class in Perl and Python
Inheritance and polymorphism in Perl and Python
Abstract classes and methods in Perl and Python
Weak references for memory management
Scripting for graphical user interfaces
Scripting for network programming
Interacting with databases
Processing XML with Perl and Python
This book serves as an excellent textbook for a one-semester undergraduate course on advanced scripting in which the students have some prior experience using Perl and Python, or for a two-semester course for students who will be experiencing scripting for the first time. Scripting with Objects is also an ideal resource for industry professionals who are making the transition from Perl to Python, or vice versa.
Authors Allen Downey and Chris Mayfield start with the most basic concepts and gradually move into topics that are more complex, such as recursion and object-oriented programming. Each brief chapter covers the material for one week of a college course and includes exercises to help you practice what you’ve learned.Learn one concept at a time: tackle complex topics in a series of small steps with examplesUnderstand how to formulate problems, think creatively about solutions, and write programs clearly and accuratelyDetermine which development techniques work best for you, and practice the important skill of debuggingLearn relationships among input and output, decisions and loops, classes and methods, strings and arraysWork on exercises involving word games, graphics, puzzles, and playing cards
The approach in this book is based on typed technologies, and the core notions fit mainstream object-oriented languages such as Java and C#. The book promotes object-oriented constraints (assertions), their specification and verification. Object-oriented constraints apply to specification and verification of object-oriented programs, specification of the object-oriented platform, more advanced concurrent models, database integrity constraints and object-oriented transactions, their specification and verification.
The FOOM methodology is very well structured, providing step-by-step guidelines on what to do and how to do each of the analysis and design activities. Many examples make the learning and utilization of the methodology easy.
