The third edition introduces multitier applications early and uses them throughout, following good object-oriented methodology. Many middle-tier and data-tier components are written as Web services.
Students create Windows database applications using Visual Basic's all-new components for database access, including the new Data Sources window, new techniques for connecting to data sources, and new controls for data binding. Stored procedures are also covered.
The Web database topics include the enhanced two-way data binding and the significantly changed data source components, including the ObjectDataSource for connecting to a data-tier component.
Each chapter includes a complete hands-on project, from opening problem statement through design and solution.
The text incorporates new features in the language, such as generics, partial classes, Web master pages and Web themes, the background worker component, and smart device applications using the new device emulators.
New IDE features are presented, including class diagrams, a Data Sources window that simplifies setting up the data source for an application, Smart Tags, AutoCorrect, an Exception Assistant for debugging exceptions, the Project Designer, Snap Lines in the Form Designer, code snippets, and the Resources folder included in the solution.
The new built-in Web server eliminates the need to use IIS for Web development and greatly simplifying the building of portable Web applications.
Security issues are addressed throughout and identified with a new margin icon.
