Simply Visual Basic 2010: An App-Driven Approach (4e)

For introductory courses in Visual Basic Programming, offered in departments of Information Technology, Computer Science or Business.

Merging the concept of a lab manual with that of a conventional textbook, the Deitels have crafted an innovative approach that enables students to learn programming while having a mentor-like book by their side. This best-seller blends the Deitel™ signature Live-Code™ Approach with their Application-Driven™ methodology.¿ Students learn programming and Visual Basic by working through a set of applications.¿ Each tutorial builds upon previously learned concepts while learning new ones. An abundance of self assessment exercises are available at the end of most chapters to reinforce key ideas.¿

This approach makes it possible to cover a wealth of programming constructs within the Visual Basic 2010 environment.

• Updated to Visual Basic 2010, the Visual Studio 2010 IDE and .NET 4.
• ASP treatment updated to ASP.NET 4.
• The hundreds of screenshots have been replaced by easier to read code listings with line numbers, syntax shading and code highlighting.
• Focus on business and personal utility examples.
• Shifted the thinking from “application development” to “app development”–many of the apps in Simply Visual Basic 2010 inspired the apps in the Deitel Developer Series books, iPhone for Programmers and Android for Programmers.
• The authors will test all of the examples and exercises on Windows 8 when it is released and post any updates on the www.deitel.com/books/simplyvb2010/.
• Integrated visual programming with Windows Forms GUI throughout, LINQ with generic collections, LINQ with database, database with Microsoft SQL Server Express, Windows Presentation Foundation (WPF) GUI and graphics, GDI+ graphics.
• App-driven, live-code approach. All of the concepts and exercises are presented in the context of real-world apps.
• Integrated debugging.
• Companion Website includes video introduction to the Visual Basic 2010 Express IDE, Before You Begin video and other resources.
• The book is supported by a growing list of online resource centers at www.deitel.com/ResourceCenters.html.
• Instructor ancillaries include PowerPoint Slides, Instructor’s Solutions Manual and Test Item File.

Signature “Live Code™ Approach” – Language features are presented in the context of a wide variety of complete working programs.

– Focuses on complete working programs.

– Enables students to confirm that programs run as expected.

– Students can download the code from the book's Companion Website (www.pearsonhighered.com/deitel) or from the authors' website (www.deitel.com).

 

Outstanding, consistent and applied pedagogy:

– Icons throughout identify Software Engineering Observations; Good Programming Practices; Common Programming Errors; Portability Tips; Performance Tips, Testing and Debugging Tips, and Look-and-Feel Observations.

– Full-color presentation, including syntax coloring, code highlighting, callouts and extensive comments

– Skills summaries and helpful self-review multiple-choice questions and answers for immediate feedback after each section

 

Early immersion in visual programming techniques and modifying Visual Basic .NET GUIs gives students a foundation for designing GUIs, concepts that they will apply throughout the book as they are taught core programming concepts. Special sections on GUI Design Guidelines and on Controls, Events, Properties & Methods.

 

Careful introduction to creating objects – Students begin to create objects and classes later in the book, while they use objects from .NET’s Framework Class Library throughout the book.

Extensive set of interesting exercises and substantial projects – Enable students to apply what they've learned in each chapter.
