Welcome to Foundation Expression Blend 2: Building Applications in WPF and Silverlight! I am very excited about this book, as I love Windows Presentation Foundation (WPF) and Silverlight, and I have a passion for teaching them both. Throughout the course of the book, I am going to take you step by step from being a novice in Blend/WPF/Silverlight to being a skilled prac- tioner, able to create your own dynamic Rich Media Applications with animations, stunning effects, and even 3D objects. As well as these innovative tools from Microsoft, you will also use some third-party applications that will really make your creations visually stunning. Because this technology is so new, only a handful of people in the world know how to develop in it, and those who can are compensated very well and are highly sought after. It's a rapidly expanding market, and more and more companies are looking for Silverlight and WPF developers-if you have those skills, then you'll be a developer in demand!

Before I describe the contents of this book and why I think you should just take it over to the counter and buy it, I would like to give you an insider's look at the SQL Server 2008 product dev- opment cycle. I believe this insight will provide you with a deeper understanding of how SQL Server is continuing to evolve. The rest of this book will show you why SQL Server is enterprise-ready. For the past 5 years, I was a program manager at Microsoft in the SQL Server product unit. During this time, I owned various features within the product, including SQL Server Agent, SQL Server Express, and most recently, database security. When I joined SQL Server in 2002, the product team was in year 3 of planning and implementing theYukon (SQL Server 2005) release. One of my first responsibilities was to own the Create Database/ Database Properties dialog in SQL Server Management Studio. After working with the user interface (UI) design team and various UI developers, we crafted the interesting grid-based dialog that you see today in Management Studio. However, arriving at the implemented Create Database dialog was not as straightforward as we wanted.

The code is free to download, so you can use the recipes immediately. Take advantage of quality, ready–made solutions to common Visual Basic programming problems Avoid the tedium of having to reinvent the wheel—focus instead on the more interesting problems specific to your application Learn from and be inspired by what the authors have done. Use their work as stepping stones to solve even more complex problems

Many would argue that the single most important job of a SQL Server database administrator is to be able to recover your database in the event of loss or damage. Pro SQL Server Disaster Recovery helps you meet that goal by showing you how to think about and plan for potential problems. You’ll learn to anticipate and reduce the likelihood of a disaster, and to mitigate the effects of a disaster when one does occur. Perhaps most importantly, you’ll learn how to prepare so that you can return a system to its normal state quickly, ensuring system availability and the continued success and operation of your business.Many SQL Server features and technologies are, or can be put to good use in disaster recovery planning. In this book, you’ll learn about powerful tools and features—such as Database Snapshots and Mirroring—for data backup and disaster recovery that are present in SQL Server 2005, and that are enhanced in SQL Server 2008. Also covered are common issues to expect when using these features. This book explores your options by examining the technical details of disaster recovery features and then applying that knowledge to practical scenarios. There’s a human side to disaster recovery planning as well. Like few other activities, disaster recovery planning requires that you work closely with a wide variety of people from all across your organization. People skills are as critical to disaster recovery planning as technical skills, and perhaps more so. This book does not leave you in the dark, but provides sound advice on how to keep disaster recovery planning projects on track, how to avoid dangerous scope creep, and how to work effectively with the variety of personality types that you will encounter.Disaster recovery planning is really about sleep. When you get the call at 3:00 am that your database is lost, don’t wake up with that icy feeling in your veins. Instead, wake up with confidence that you have a plan in place, a plan that you’ve practiced, that management has bought into, a plan that you can execute even while half–asleep to get your database, your company, and your job back on track.

T he purpose of this book is to teach you the fundamentals and mechanics of the C# progr- ming language. Most books teach programming primarily using text. That's great for novels, but many of the important concepts of programming languages can best be understood through a combination of words, figures, and tables. Many of us think visually, and figures and tables can help clarify and crystallize our und- standing of a concept. In several years of teaching programming languages, I have found that the pictures I drew on the whiteboards were the things that most quickly helped the students understand the concepts I was trying to convey. Illustrations alone, however, are not sufficient to explain a programming language and platform. The goal of this book is to find the best combination of words and illustrations to give you a thorough understanding of the language, and to allow the book to serve as a reference resource as well. This book is written for anyone who wants an introduction to the C# programming language-from the novice to the seasoned programmer. For those just getting started in programming, I have included the basics. For seasoned programmers, the content is laid out succinctly, and in a form that will allow you to go directly to the information required without having to wade through oceans of words. For both sets of programmers, the content itself is presented graphically, in a form that should make the language easy to learn.

When .NET first appeared, it introduced a small avalanche of new technologies. There was a whole new way to write web applications (ASP.NET), a whole new way to connect to databases (ADO.NET), new typesafe languages (C# and VB .NET), and a managed runtime (the CLR). Not least among these new technologies was Windows Forms, a library of classes for building W- dows applications. Although Windows Forms is a mature and full-featured toolkit, it's hardwired to essential bits of Windows plumbing that haven't changed much in the past ten years. Most significantly, Windows Forms relies on the Windows API to create the visual appearance of standard user interface elements such as buttons, text boxes, check boxes, and so on. As a result, these ing- dients are essentially uncustomizable. For example, if you want to create a stylish glow button you need to create a custom c- trol and paint every aspect of the button (in all its different states) using a lower-level drawing model. Even worse, ordinary windows are carved up into distinct regions, with each control getting its own piece of real estate. As a result, there's no good way for the painting in one c- trol (for example, the glow effect behind a button) to spread into the area owned by another control. And don't even think about introducing animated effects such as spinning text, sh- mering buttons, shrinking windows, or live previews because you'll have to paint every detail by hand.

Author Eric Griffin shows you how to mix applications and share your hybrids with the world, using the Popfly Mashup Creator and Popfly Web Page Creator.

The Ajax craze is sweeping the world, and there is no shortage of libraries from which to choose to make it all easier to develop. One of those libraries has risen near the top in the Java space, and that library is DWR. DWR, or Direct Web Remoting, allows you to treat your Java classes running on the server as if they were local objects running in the browser, bringing the full power of your server–side business logic to the client without the usual problems that entails. In this book, you will: Explore DWR and all it offers Find six full, working applications that use DWR, instead of a lot of theoretical musings Learn by example, more importantly, by doing, as you tear the applications apart, see what makes them tick, and even extend them at your own pace In the end, you’ll have a great feel for what DWR offers and how Ajax can bring the world of Web 2.0 to your doorstep, and you’ll have a good time doing it.

Silverlight is a lightweight browser plug–in that frees your code from the traditional confines of the browser. It’s a rules–changing, groundbreaking technology that allows you to run rich client applications right inside the browser. Even more impressively, it’s able to host true .NET applications in non–Microsoft browsers (like Firefox) and on non–Microsoft platforms (like Mac OS X). Silverlight is still evolving fast, and you need a reliable guidebook to make sense of it.With four–color graphics and screenshots throughout, Pro Silverlight 2 in C# 2008 is the perfect reference: you’ll learn about the features that put Silverlight in direct competition with Adobe Flash, such as rich support for 2D drawing, animations, and media playback, and best of all, you’ll experience the plumbing of .NET and the design model of WPF through Silverlight—all of the same .NET technology that developers use to design next–generation Windows applications. Author Matthew MacDonald provides an expertly crafted tutorial, written from professional developer to professional developer. You’ll learn to create rich media applications using Silverlight in the environment you’re most productive in, no matter what the target platform.

I remember the first time I got to play with Windows PowerShell-I had some spare time on my hands, and after reading a blog post, I quickly set off to download the unofficial pre-release bits that were available at the time. I originally had very low expectations about the tool-all I wanted was a shell that is up to par with its UNIX cousins. Boy, was I wrong! The moment I learned about object pipelines, I knew this tool was going to change the way I think about automating tasks on Windows. Fast forward a couple of months, and here I am, so much in love with Power- Shell that I even wrote a whopping 400-page book about it. Why Another Book on Windows PowerShell? As much as I like PowerShell, its plain-console looks make it very easy for people to dismiss it without really seeing what lies beneath the surface. I feel it is still largely undiscovered-I know many professionals who have yet to try it out. When administrators see PowerShell for the first time, many simply shrug, assuming it's just another version of the primitive command prompt we inherited from DOS.

Microsoft Silverlight allows you to create rich multimedia interfaces with the power and flexibility of Flash, but with the extensibility and the great tools that .NET offers. With Silverlight and ASP.NET Revealed, you’ll learn to use Microsoft’s Silverlight technology in conjunction with ASP.NET and Visual Studio 2008 (code name Orcas). You will ultimately incorporate Silverlight into an ASP.NET web site and use the ASP.NET controls that render Silverlight content. You’ll get the basics of Silverlight, too, making this book a must–read for any web developer curious about Silverlight.

Building a Data Warehouse: With Examples in SQL Server describes how to build a data warehouse completely from scratch and shows practical examples on how to do it. Author Vincent Rainardi also describes some practical issues he has experienced that developers are likely to encounter in their first data warehousing project, along with solutions and advice. The relational database management system (RDBMS) used in the examples is SQL Server; the version will not be an issue as long as the user has SQL Server 2005 or later.The book is organized as follows. In the beginning of this book (chapters 1 through 6), you learn how to build a data warehouse, for example, defining the architecture, understanding the methodology, gathering the requirements, designing the data models, and creating the databases. Then in chapters 7 through 10, you learn how to populate the data warehouse, for example, extracting from source systems, loading the data stores, maintaining data quality, and utilizing the metadata. After you populate the data warehouse, in chapters 11 through 15, you explore how to present data to users using reports and multidimensional databases and how to use the data in the data warehouse for business intelligence, customer relationship management, and other purposes. Chapters 16 and 17 wrap up the book: After you have built your data warehouse, before it can be released to production, you need to test it thoroughly. After your application is in production, you need to understand how to administer data warehouse operation.

The Oracle database engine has become a huge piece of software. This not only means that a single human can no longer be proficient in using all the features provided in recent versions, but it also means that some of them will rarely be used. Actually, in most situations, it is enough to know and take advantage of a limited number of core features in order to use the Oracle da- base engine efficiently and successfully. This is precisely why in this book I will cover only the features that, based on my experience, are necessary to troubleshoot most of the databa- related performance problems you will encounter. Structure of This Book This book is divided into five parts: Part 1 covers some basics that are required to read the rest of the book. Chapter 1, "e;Perf- mance Problems,"e; explains not only why it is essential to approach performance problems at the right moment and in a methodological way but also why understanding business needs and problems is essential. Chapter 2, "e;Key Concepts,"e; describes the operations carried out by the database engine when parsing and executing SQL statements. It also introduces some terms that are frequently used in the book. Part 2 explains how to approach performance problems in an environment that is based on the Oracle database engine. Chapter 3, "e;Identifying Performance Problems,"e; provides a detailed analysis road map for identifying performance problems. Several tools and te- niques that can be used with it are also described.

Designing for the Web is a wonderful thing. The ability to publish something and have it appear immediately and globally is an empowering feeling. I'll never forget the first rush I felt when, as a print designer, I could simply "e;upload"e; some files and have them be immediately visible, rather than waiting in trepidation for the boxes to return from the printer. Back then the Web was simpler, there were fewer materials and tools, and "e;styling"e; was something you hacked together using bizarre hacks and workarounds to achieve even the simplest of tasks. The browser landscape was equally testing. Now we're in a much better position. We have a wonderful thing called CSS that allows us to style pages with concise style rules and leave the HTML to describe the content, not the pr- entation. Content can be repurposed for different media. But anyone keen to learn web design (from scratch, or to improve their existing skills) has a bewildering job on their hands. The publishing market is saturated with good books on web design, HTML, and CSS. Yet if you were asked for a single book that encompasses all three, and that someone could understand without assuming any prior "e;Internet knowledge,"e; what would you recommend? Still trying to think of one? A regular contributor to . net/Practical Web Design magazine, Craig Grannell has written The Essential Guide to CSS and HTML Web Design for this purpose.

Together they have crafted a technically sound and authoritative fountain of information on working with spatial data in the Oracle database.

Flex is a very powerful and versatile technology for creating web application front-ends. But what every good web application needs is a robust data source, be it XML, or a database. Flex is very adaptable in terms of connecting to data sources, and that is the main focus of this book.In Foundation Flex for Developers, author Sas Jacobs assumes that you've got the basics of Flex down already, and explores in detail how to create professional data-centric Flex 2 and Flex 3 applications. In the first half of the book, she starts off with a brief exploration of Flex and ActionScript 3.0, before looking at application essentials in detail—creating custom components, user and web browser interactions, binding, formatting, and validating data, debugging, and more.In the second half of the book, the focus is on connecting Flex to data sources, and covers XML, LiveCycle Data Services, PHP, ASP.NET, and ColdFusion in detail, via a series of step-by-step case studies. Covers Flex application basics Covers connecting Flex 2 and Flex 3 to a variety of Data Sources Includes several complete case studies

Many Flex books cover the basics—this book does something different, and goes far further. The authors, leading Flash platform developers at Almer/Blank, working with Adobe User Group communities, are the creators of the Rich Media Exchange (RMX), a social media network for Adobe developers. In covering just how the RMX was built, this book contains all the knowledge you need to build similar large-scale rich Internet applications with Adobe Flex.From the inception of the idea through to deployment, the authors show the techniques needed to plan and build advanced applications. You'll learn how to use forms, styles, validators, video, sound analysis, and framework caching, ensuring you make the most of the features introduced in Flex 3.Powerful applications require solid back ends. This book shows how to hook up a Flex application to PHP back-end systems such as Drupal and OpenAds. You'll learn how various parts of the RMX were built, including the blogs, event calendar, jobs board, and advertising system—elements that come together to really showcase the power of Flex.The RMX is built by Adobe developers for Adobe developers—a rewarding community relationship that guarantees results. The same spirit is carried into this book, with the authors wanting and helping to take you to the next level of Flash application development.

Flash has long been one of the most approachable, user-friendly tools for creating web-based animations, games, and applications. This has contributed to making it one of the most widely used programs for creating interactive web content. With each new version of Flash, ActionScript, its built-in scripting language, has become more powerful and a little more complex, too. ActionScript, now at version 3.0, has significantly matured as a programming language, bringing power and speed only previously dreamed about to Flash-based animation, going far beyond traditionally used keyframes and tweens.The material inside this book covers everything you need to know to harness the power of ActionScript 3.0. First, all the basics of script-based animation and setting up an ActionScript 3.0 project are covered. An introduction to object-oriented programming follows, with the new syntax, events, and rendering techniques of ActionScript 3.0 explained, giving you the confidence to use the language, whether starting from scratch or moving up from ActionScript 2.0.The book goes on to provide information on all the relevant trigonometry you will need, before moving on to physics concepts such as acceleration, velocity, easing, springs, collision detection, conservation of momentum, 3D, and forward and inverse kinematics. In no time at all, you'll both understand the concepts of scripted animation and have the ability to create all manner of exciting animations and games.

Functional programming (FP) is the future of .NET programming, and F# is much more than just an FP language. Every professional .NET programmer needs to learn about FP, and there's no better way to do it than by learning F#, and no easier way to learn F# than from Foundations of F#.If you're already familiar with FP, youll find F# the language youve always dreamed of. All .NET programmers will find F# an exciting real-world alternative to C# and Visual Basic. This book is likely to have many imitators, but few true competitors. Written by F# evangelist Rob Pickering, and tech reviewed by F#'s main designer, Don Syme, this is an elegant, comprehensive introduction to all aspects of the language and an incisive guide to using F# for real-world professional development. F# is the future of programming (not just on .NET), and the future is now.

Relational databases hold data, right? They do indeed, but to think of a database as nothing more than a container for data is to miss out on the profound power that underlies relational technology. A far more powerful way of thinking lies in relational technologys foundation in the mathematical disciplines of logic and set theory.Databases contain truths or propositions describing some area of interest such as a business. Those truths are organized into sets. Operations from logic and set theory can be applied to existing sets of truths to derive new sets of truths. Applied Mathematics for Database Professionals introduces you to this way of thinking, to the logic and set theory that underlies relational database technology. All this may sound abstract now, but there are profound benefits from the deeper understanding youll gain from this book.The math that you'll learn in this book will put you above the level of understanding of most database professionals today. You'll better understand the technology and be able to apply it more effectively. You'll avoid data anomalies like redundancy and inconsistency. Understanding whats in this book will take your mastery of relational technology to heights you may not have thought possible.This book is reviewed and endorsed by C. J. Date and features a foreword by the same.

Exploring C++ uses a series of self–directed lessons to divide C++ into bite–sized chunks that you can digest as rapidly as you can swallow them. The book assumes only a basic understanding of fundamental programming concepts (variables, functions, expressions, statements) and requires no prior knowledge of C or any other particular language. It reduces the usually considerable complexity of C++.The included lessons allow you to learn by doing, as a participant of an interactive education session. You’ll master each step in one sitting before you proceed to the next. Author Ray Lischner has designed questions to promote learning new material. And by responding to questions throughout the text, you'll be engaged every step of the way.

In the four years that the Sun, IBM, and MyFaces implementations have been ava- able, the MyFaces project has arguably been the front-runner when it comes to in- vation and dexterity. It also is the most responsive to user issues and has a vibrant community that ensures progression (you can always find free support on the mailing lists). With JavaServer Faces (JSF) 2.0 around the corner, preparation is already under way as the committers quickly review the early access draft and plan for MyFaces 2.0. This "e;anarchic collaboration,"e; a term coined by Roy Fielding, is the essence of the Apache MyFaces project: many talented people share information with a single-minded objective to make JSF a pleasurable developer experience for all. The Tomahawk, Tri- dad, Tobago, Orchestra, and MyFaces implementations have been downloaded over a million times. Before the Sun JSF 1.2 implementation was released, we could safely say the MyFaces implementation was the only reliable way to build production JSF appli- tions. Even today, many developers are happy with simply using MyFaces 1.1.x and Facelets to form a potent combination. This book assumes you are interested in JSF and component-oriented development.

Visual Basic 2008 (VB 2008) is relatively easy to learn for anyone familiar with another object-oriented language. Even someone familiar with Visual Basic 6.0 who is looking for an object-oriented language will find VB 2008 easy to pick up. However, though VB 2008, coupled with .NET, provides a quick path for creating simple applications, you still must know a wealth of information and understand how to use it correctly in order to produce sophis- cated, robust, fault-tolerant applications. We teach you what you need to know and explain how best to use your knowledge so that you can quickly develop true VB 2008 expertise. Idioms and design patterns are invaluable for developing and applying expertise, and we show you how to use many of them to create applications that are efficient, robust, fault-tolerant, and exception-safe. Although many are familiar to C++ and Java programmers, some are unique to .NET and the Common Language Runtime (CLR). We show you how to apply these indispen- ble idioms and design techniques to seamlessly integrate your VB 2008 applications with the .NET runtime, focusing on the new capabilities of VB 2008. Design patterns document best practices in application design that many different p- grammers have discovered and rediscovered over time. In fact, .NET itself implements many well-known design patterns. You will see these practices detailed throughout this book. Also, it is important to note that the invaluable tool chest of techniques is evolving constantly.
