Part I: Getting Started

1. IDE

Describes the integrated development environment (IDE). It explains the IDE's windows and how to customize the IDE. It also explains tools that provide help while you're programming such features as the Object Browser and the code window's Intellisense.

2. Controls in General

Describes general control concepts. It explains how to add controls to a form, how to read and change a control's properties at design time and at run time, and how to use some of the more complicated control properties (such as Dock and Anchor). This chapter shows how to catch and respond to events, and how to change event handlers in code.

3. Program and Module Structure

Analyzes a simple Visual Basic program and explains the structure created by Visual Studio. It describes the program's code regions and comments, and tells how you can use similar techniques to make your code more readable and manageable.

4. Data Types, Variables, and Constants

Explains the standard data types provided by Visual Basic. It shows how to declare and initialize variables and constants, and explains variable scope. It discusses value and reference types, passing parameters by value or reference, and creating parameter variables on the fly. It also explains how to create arrays, enumerated types, and structures.

5. Operators

Describes the operators a program uses to perform calculations. These include mathematical operators (+, *, \), string operators (&), and Boolean operators (And, Or). The chapter explains operator precedence and type conversion issues that arise when an expression combines more than one type of operator (for example, arithmetic and Boolean).

6. Subroutines and Functions

Explains how you can use subroutines and functions to break a program into manageable pieces. It describes routine overloading and scope.

7. Program Control Statements

Describes the statements that a Visual Basic program uses to control code execution. These include decision statements (If Then Else, Select Case, IIF, Choose) and looping statements (For Next, For Each, Do While, While Do, Repeat Until).

8. Error Handling

Explains error handling and debugging techniques. It describes the Try Catch structured error handler in addition to the older On Error statement inherited from earlier versions of Visual Basic. It discusses typical actions a program might take when it catches an error. It also describes techniques for preventing errors and making errors more obvious when they do occur.

9. Introduction to Windows Forms Controls

Explains the Visual Basic's standard controls that you can use on Windows forms. It describes the most useful properties, methods, and events provided by these controls, and it gives examples showing how to use them. It also describes cases where these controls rely on each other. For example, several controls such as the ToolBar obtain images from an associated ImageList control.

10. Forms

Explains typical uses of forms. It tells how to build partially transparent forms for use as splash, login, and About forms. It describes form cursors and icons, how to override WndProc to intercept a form's Windows messages, how to make a Multiple Document Interface (MDI) application, and how to implement a Most Recently Used (MRU) file list. It does not cover all of the Form object's properties, methods, and events in detail; those are described in Appendix H. Form Objects.

11. Database Controls and Objects

Explains how to use Visual Basic's standard database controls. These include database connection components that handle connections to a database, DataSet components that hold data within an application, and data adapter controls that move data between data connections and DataSets.

12. Custom Controls

Explains how to build your own customized controls that you can then use in other applications. It covers the three main methods for creating a custom control: derivation, composition, and building from scratch. This chapter also provides several examples that you can use as a starting point for controls of your own.

13. Drag-and-Drop, and the Clipboard

Explains how a Visual Basic program can support drag-and-drop operations. It tells how your program can start a drag to another application, how to respond to drag operations started by another application, and how to receive a drop from another application. This chapter also explains how a program can copy data to and from the clipboard. Using the clipboard is similar to certain types of drag-and-drop operations, so these topics fit naturally in one chapter.

Part II: Object-Oriented Programming

14. OOP Concepts

Explains the fundamental ideas behind object-oriented programming. It describes the three main features of OOP: encapsulation, polymorphism, and inheritance. It explains the benefits of these features and tells how you can take advantage of them in Visual Basic.

15. Classes and Structures

Explains how to declare and use classes and structures. It explains what classes and structures are, and it describes their differences. It shows the basic declaration syntax and tells how to create instances of classes and structures. It also explains some of the trickier class issues (such as private class scope, declaring events, and shared variables and methods).

16. Namespaces

Explains namespaces. It tells how Visual Studio uses namespaces to categorize code and to prevent name collisions. It describes a project's root namespace, tells how Visual Basic uses namespaces to resolve names (such as function and class names), and tells how you can add namespaces to an application yourself.

17. Collection Classes

Explains classes included in Visual Studio that you can use to hold groups of objects. It describes the various collection, dictionary, queue, and stack classes; tells how to make strongly typed versions of those classes; and gives some guidance on deciding which class to use under different circumstances.

18. Generics

Explains templates that you can use to build new classes designed to work with specific data types. For example, you can build a generic binary tree and then later use it to build classes to represent binary trees of customer orders, employees, or work items.

Part III: Graphics

19. Drawing Basics

Explains the fundamentals of drawing graphics in Visual Basic .NET. It describes the graphics namespaces and the classes they contain. It describes the most important of these classes, Graphics, in detail. It also describes the Paint event handler and other events that a program should use to keep its graphics up to date.

20. Brushes, Pens, and Paths

Explains the most important graphics classes after Graphics: Pen and Brush. It tells how you can use Pens to draw solid lines, dashed lines, lines with custom dash patterns, and lines with custom lengthwise stripe patterns. It tells how to use Brushes to fill areas with colors, hatch patterns, linear color gradients, color gradients that follow a path, and tiled images. This chapter also describes the GraphicsPath class, which represents a series of lines, shapes, curves, and text.

21. Text

Explains how to draw strings of text. It shows how to create different kinds of fonts, determine exactly how big text will be when drawn in a particular font, and use GDI+ functions to make positioning text simple. It shows how to use a StringFormat object to determine how text is aligned, wrapped, and trimmed, and how to read and define tab stops.

22. Image Processing

Explains how to load, modify, and save image files. It shows how to read and write the pixels in an image, and how to save the result in different file formats such as BMP GIF, and JPEG. It tells how to use images to provide auto-redraw features, and how to manipulate an image pixel by pixel, both using a Bitmap's GetPixel and SetPixel methods and using "unsafe" access techniques that make pixel manipulation much faster than is possible with normal GDI+ methods.

23. Printing

Explains different ways that a program can send output to the printer. It shows how you can use the PrintDocument object to generate printout data. You can then use the PrintDocument to print the data immediately, use a PrintDialog control to let the user select the printer and set its characteristics, or use a PrintPreviewDialog control to let the user preview the results before printing.

24. Reporting

Provides an introduction to Crystal Reports, a tool that makes generating reports in Visual Basic relatively easy. The chapter explains the basics of Crystal Reports and steps through an example that builds a simple report.

Part IV: Interacting with the Environment

25. Configuration and Resources

Describes some of the ways that a Visual Basic program can store configuration and resource values for use at run time. Some of the most useful of these include environment variables, the Registry, configuration files, and resource files.

26. Streams

Explains the classes that a Visual Basic application can use to work with stream data. Some of these classes are FileStream, MemoryStream, BufferedStream, TextReader, and TextWriter.

27. File-System Objects

Describes classes that let a Visual Basic application interact with the file system. These include classes such as Directory, DirectoryInfo, File, and FileInfo that make it easy to create, examine, move, rename, and delete directories and files.

28. Useful Namespaces

Describes some of the most commonly useful namespaces defined by the .NET Framework. It provides a brief overview of some of the most important System namespaces and gives more detailed examples that demonstrate regular expressions, XML, cryptography, reflection, threading, and Direct3D.
