Introduction to Windows Vista

Introduction

Windows Vista includes several new user interface elements and features that improve the user experience These new features provide new opportunities for developers when creating applications for Windows Vista This section introduces some of these new features

Objectives

After completing this section, you will be able to:

• Describe what is new for developers in Windows Vista

• Describe the user experience for Windows Vista

Trang 10

What Is New in Windows Vista for Developers?

Fundamentals

Windows Vista includes improvements to the fundamentals that form the basis for

application development New features enable developers to:

• Build secure applications Windows Vista provides:

• User Account Protection, which enables users to change common settings

without requiring administrative privileges Standard users are prevented from making potentially dangerous changes to their computers; they can run most applications

• Code Access Security (CAS), which minimizes the attack surface of an

application by enabling only the minimum privileges needed for applications to function correctly

• Windows Service Hardening, which restricts critical Windows services from

making unauthorized changes in the file system, registry, network, or other resources

• Microsoft Internet Explorer® 7, which includes a protected mode that helps

protect user data and configuration settings

Trang 11

• Develop reliable applications Windows Vista provides:

• An extensive set of new APIs for developers to make applications reliable for end users and to diagnose application issues

• Enhanced developer portal services, which enable analysis of application

behavior in real-world customer deployments

• Write robust application installers Windows Vista provides:

• New tools to help create installers that put application files in place seamlessly and create a consistent uninstall experience

• Improvements to ClickOnce to enable rapid application setup with minimal overhead ClickOnce is an application deployment technology that makes deploying a Windows Forms-based application as easy as deploying a Web application

Presentation

One of the new features in Windows Vista applications is the appearance of an

application The new Windows Presentation Foundation (formerly code-named Avalon) and the new Aero shell offer opportunities for developers and designers to collaborate on

innovative new application experiences The new features include Windows Sidebar and gadgets

Communications

The Windows Communication Foundation provides industry-leading Web services support, new peer-to-peer features, Really Simple Syndication (RSS) capabilities, and core networking enhancements Windows Vista has a host of communication features for building today’s connected applications New features enable developers to:

• Build connected applications Windows Communication Foundation APIs make it simple to consume and expose a new generation of Web services New peer-to-peer functionality lets you discover and interact with other nearby devices

• Build mobile applications Windows Vista provides new capabilities for detecting network and power state, and it automatically synchronizes application data when necessary

Trang 12

Data

Windows Vista includes capabilities to make data searching faster (IFilter), a transacted

file system built on NTFS, integrated support for RSS, and a common XML Paper

Specification (XPS) document format New features enable developers to:

• Perform new ways to search and organize information Windows Vista provides:

• New ways to search and organize files and data, using application metadata and

search in addition to traditional file name and folder hierarchies Developers can extend the system to ensure that documents and data created by their software seamlessly integrate into the default search-and-organize experience

• New controls, such as the Instant Search box and Enhanced Column Headers

• Integrate data Windows Vista provides:

• New features that make it easier for applications to find and share the data users

want to see

• A new XML-based file format—the same one used as the default in Office 12—

makes it possible to manipulate data in any document

• Really Simple Syndication (RSS) APIs and a shared RSS store will allow

developers to easily RSS-enable Windows Vista applications and provide central access to feeds, lists, and attachments for users

Productivity and tools

Microsoft has shipped a set of its industry-leading tools to enable developers to easily

utilize these new features of the operating system

Trang 13

The Windows Vista User Experience

What is the Windows Vista User Experience?

The Windows Vista User Experience specifies guidelines that govern the look and feel of

the operating system and applications that run on the operating system These guidelines

express how the user interacts with the system and the feelings it should evoke

Aero Aesthetics

Aero is the name for the new user experience in Windows Vista, representing both the

values embodied in the aesthetics and the vision behind the user interface Aero is an

acronym for Authentic, Energetic, Reflective and Open The Aero UI for Windows Vista

is clean, efficient and fast for frequent, familiar tasks and easy to learn for infrequent

tasks and initial experiences It also includes new transparencies, animations, and visual

effects

What can developers do to make a Windows Vista User Experience

application?

The Aero theme file and APIs make it easy to bring the Aero design to your Windows

Vista–based applications Applications that use the Aero theme will be consistent with

Windows Vista while providing the flexibility for application differentiation

Trang 14

For most applications, application developers need to do just a few things to create the

Windows Vista User Experience:

• Do not hard code any colors All colors should be based on system or theme metrics

and use comctl32.dll v6 This will give developers the latest look and feel for their

buttons, text boxes, and other UI elements

• Use theme-painting APIs If developers want to develop any elements that look like

standard system elements, they should use the theme-painting APIs

• Use the correct color, layout, and writing styles

• Use the Windows Vista User Experience Wizard and Task Dialog boxes The

Windows Vista User Experience Wizard framework gives application developers the ability to use the Windows Vista User Experience style in their dialog boxes In

Windows Vista, task dialog boxes will replace the message box or most other

instances of a single-step prompt or error message Task dialog boxes add such

features as the main instruction and supporting text and links to error messages

For more information on the Windows Vista User Experience, see the Windows

Vista Experience Web site on the Microsoft MSDN® Web site
