This book has been designed to give you the Visual Basic. NET coverage you just won't find in any other book. Other books often omit not only the larger topics, like deploying your program after you've created it, but also the smaller ones like covering just about every Windows and Web control that comes with Visual Basic.
NET in depth-from the text box control to three-state checkboxes, from datetime pickers to hot tracking tab controls, and from Web page validation controls to ad rotators. And the advanced topics are here too, like creating your own Windows and Web controls, writing Windows and Web services, distributed data applications, multithreading, deploying applications, and more.
How This Book Works The task-based format we use in this book is the one many programmers appreciate, because programming is a task-based business. Rather than reading about subjects in the order I might think best, you can go directly to your topic of interest and find the bite-sized nugget of information you need.
And best of all, there's a working example in code for almost every programming topic in the book. The actual process of programming is not abstract; it's very applied, and so instead of vague generalities, we get down to the specifics-all the specifics-that give you everything you need to understand and use Visual Basic.
In the old days, programming books used to be very top-down, with chapters on subjects like "Conditional Branching," "Loop Structures," "Variable Declarations," and so forth. But who sits down to program by saying, "I'm about to create a conditional program flow branch"? Instead, programmers are more interested in performing useful tasks, like adding buttons, menus, list boxes, or toolbars to a window; creating graphics animation; creating dialog boxes; creating setup programs; working with files; linking to Web pages; multi-threading; supporting online help; and so on.
And this book is written for programmers. Because this book is written for programmers, each chapter is broken up into dozens of practical programming tasks. After selecting the chapter you want, you can turn to the Table of Contents, the Index, or the first page in that chapter to find the task you're interested in. Hundreds of tasks are covered in this book, chosen to be the ones that programmers want to see.
In addition, this book is filled with examples-nearly eight hundred examples- covering nearly every Visual Basic. NET programming area there is. These examples are bite-sized and to the point, so you don't have to wade through a dozen files trying to understand one simple topic. And they're as comprehensive as I could make them, covering every programming area in the book.
NET is in this book, and that's a lot of ground to cover. From a complete language reference to ADO. NET database programming, from creating Web applications to dragging and dropping data adapters onto forms, and from creating Windows and Web controls to setup programs, it's all here or almost all of it anyway!
Here's some of what we'll see in this book: All the examples in this book have been tested by at least two people on two different machines, and each example has been carefully verified to work as it should. Here's an important note—in the past, Microsoft has changed Visual Basic without changing major or minor version number, and these unannounced changes have meant that people with the new Visual Basic can't get some examples in the book to work—see the readme.
That's just some of what's coming up—Visual Basic. I try my best to keep up with these unannounced changes. NET is a big topic. And if you have suggestions for more. If you suspect it has. One of the data source objects built into the Internet Explorer. You'll also see many tips throughout the book. In the formal definition of each statement. The Internet Explorer actually does have a number of data source objects that you can use to work with recordsets directly with scripting languages in the browser.
New Also. And when there's more code that I'm not showing to save space. And you'll also see notes. Tips look like this one from Chapter Tip Needing a server roundtrip to access your data can slow things down considerably.
Note In Visual Basic 6. Public Class Form1 Inherits System. For example. Conventions There are a few conventions in this book that you should know about.
What You'll Need To use this book. IIS can be running on your local machine. Note that although comes on the Windows CDs. Knowing some SQL will be a good idea to work with data applications.
In addition. To work with databases. I use SQL Server here. At times. You don't need to know either to read this book. I've written an entire HTML 4. In the meantime. NET now. As I said. About three dozen of those groups are hosted by Microsoft. Here are a few starter pages from Microsoft: NET initiative And that it. Although the content varies in accuracy. Resources Where can you go for additional Visual Basic support?
You can find Visual Basic user groups all over. Visual Basic 6. The difference between Visual Basic. Understanding the IDE and how to use it—and mastering some fundamental Visual Basic concepts—will give us the foundation we need for the rest of the book. In this book. NET and the previous version. NET into this book as will fit. I use Visual Basic. Chapter 1: I'll start with an overview of Visual Basic.
Almost this entire book has been rewritten. Why the big change? The reason is Visual Basic itself. NET also called VB. Instead of superimposing some abstract structure on the material in this book. A great number of techniques that you've probably learned carefully are now completely different.
In this chapter. In so doing. In time. All of which means that there's a terrific amount of material we need to cover—so I'm going to pack as much Visual Basic. This includes learning how to create Visual Basic projects. Our coverage of the new Visual Basic is not going to be like some other books that hold their topic at an arm's length and just give you dry documentation.
Visual Basic introduced unheard-of ease to Windows programming—just build the program you want. And it's also no secret that there have been massive changes in the latest version. Many Visual Basic programmers do not have formal programming training.
NET concepts such as Windows and Web forms. It's no secret that Visual Basic is the most popular programming tool available today. This book is written from the programmer's point of view. NET a lot myself. Visual Basic has a long and.
If you've read previous editions of this book. I'll organize it the way programmers want it—task by task. When it first appeared. Besides the biggest change—integrated support for Web development—the very syntax of Visual Basic has undergone tremendous changes. NET has been almost three years in the making. Visual Basic has gotten more complex.
As programming has matured. And we'll look at those practices from the viewpoint of programmers who program for a living. Because there are so many details one has to master. Rather than getting lost in the details. Before we start covering all the details in Visual Basic in depth. In fact. We'll take a look at those practices in this chapter. Figure 1.
Web forms that come to you across the Internet. Generally speaking. I'm not going to go into the details here. I'll take a look at Windows forms here first. This brings up the New Project dialog box you see in Figure 1. The Visual Basic New Project dialog box. Creating a Windows Application To create an application based on Windows forms. Now click the OK button to create this new Visual Basic project. The window you see at the center of Figure 1.
In a move that's very familiar to Visual Basic programmers. Visual Basic creates a new Windows project and gives you the result you see in Figure 1. To add a text box to Form1. The genius of Visual Basic has always been that it's visual. The boxes you see around the text box are sizing handles. Designing a new Windows application. Windows Application project type in the Templates box.
Now click the Windows Forms item in the toolbox so the toolbox displays the possible controls you can use in Windows forms. This adds a text box to Form1. I'll just add two Windows controls to this form—a text box and a button.
When you click the button. You also can name the new project—I'll name it WinHello—and specify where to store it—I'll store it in the c: In this case. You can see the toolbox to the left of Form1 in Figure 1. The next step is to customize them. Adding a text box to a Windows application. These are the controls that will appear in our application. You set properties of objects such as this button to customize them. The Properties window lists properties like the Text property on the left and their values on the right.
Adding a button to a Windows application.
Click the Text property no longer the Caption property of Visual Basic 6. To associate code with the button. In the same way. Customizing button text. Customizing a text box's text. Visual Basic has done a lot of programming for us to get us to this point. To close the application. Find the part of the code that handles clicks of the button. EventArgs Handles Button1.
Editing code in a Windows application. Click End Sub To place the text we want in the text box when the user clicks the button. That's it—our first program is a success. Click TextBox1. The application starts. Visual Basic will create the new Web application. Running a Windows application. This is the magic of Visual Basic—with one line of code. When you click the OK button. This application will do the same as the Windows application we've just seen.
Visual Basic will find it and use that server by default. Tip As Visual Basic programmers know. In the early days of Windows. To create a Web application. That's our first Visual Basic application. Make sure you save the WinHello application Visual Basic will save all files when it runs an application. You can enter the location of your server in the Location box in the New Projects dialog box. Give this new application the name WebHello.
If you look in the IDE's title bar and in the tabs above the code window in Figure 1.

Now we can design our new Web application just as we did the Windows application—click the Web forms item in the toolbox. Designing a Web application. As you also can see in Figure 1. You can see a note in the Web form under design—called a page—at the center of the IDE that says that we're using the Grid layout mode. The other layout mode is the Flow layout mode. Creating a Web application. If your Web application happens to start in Flow layout mode.
In this mode. Adding code to a Web application. We can add the same code to handle the button click as before. Adding controls to a Web application. Click End Sub and add this code: NET is following the lead of Java. That's all it takes—now run the application by selecting the Debug Start menu item.
Anyone with a browser can look at the application on the Internet. To see how console applications work.
Then click OK to create the new project. Behind the scenes. That's our first Web application—to close the application. NET has been storing the application's files on the Web server automatically—no special uploading needed.
This gives one the feeling once again that VB. The application comes up in your browser. Name this new project ConsoleHello. NET—console applications. These applications are command-line based and run in DOS windows. As you can see.
If you're like me. Running a Web application. Web applications like this will make Web development a great deal easier and more popular on IIS platforms. When the console application is run. As we'll see in more depth in Chapter 3. The code here looks like this: Module Module1 Sub Main End Sub End Module Console applications are based on Visual Basic modules that are specifically designed to hold code that is not attached to any form or other such class.
Visual Basic opens the project directly to a code window. Notice also the Sub Main procedure here. Coding a Console application. Creating a Console application. When you create this new project.
Visual Basic .NET Black Book by Steven Holzner
Module Module1 Sub Main System. Console class is part of the. The System. NET framework class library. Running a Console application. To organize all those classes. We can display our "Hello from Visual Basic" message in this console application using the WriteLine method.
Windows applications are already familiar to Visual Basic 6. This gives classes their own space and stops conflicts between the various names in such classes. Console class. NET uses namespaces. I'll take a look at what's new in overview now. We'll become more familiar with namespaces starting in Chapter 2.
This method is part of the System. We'll get a good look at the OOP issues like these in Chapters 11 and Some programmers have complained that Microsoft is trying to turn Visual Basic into Java. NET does not support multiple inheritance. Those are the three application types with user interfaces: Windows applications.
Not only has the fundamental structure of Visual Basic projects like Windows applications become different. What's New in VB. This change will take some time for many accomplished VB programmers to come to terms with. Web services are applications that run on Web servers and that communicate with other programs. Rather than asking what's new. One of the biggest hurdles that VB6 programmers will have to overcome is the great change in Visual Basic syntax.
A threaded application can do a number of different things at the same time. Console applications. Microsoft has changed all that.
These threads can communicate with each other. As we've also seen. There's also an additional new type of application—one that doesn't have a built-in user interface: Web services. All items. The changes are extensive. One longstanding complaint about Visual Basic has been that it didn't offer a serious programming syntax. This means.
Version 4. We'll note the details of these changes throughout the book. We can't cover all the changes from Visual Basic 6. One of the biggest changes in VB. NET is that now everything is object oriented. Web applications. NET is far bigger. Be warned: Like Java. You can also create multithreaded applications in VB. Not only has how you design applications and what types of projects you can create changed. NET framework that underlies VB.
You can view these applications in any browser—the application will tailor itself to the browser's capabilities. I'll list them in overview in more detail here. Microsoft's Web server technology. NET versions although. The reason for this. There are two ways to create your own Web server controls: NET Framework.
Web services are made up of code that can be called by other components on the Internet or applications that use Internet protocols. Web development is now an integral part of VB.
Web services may be used. NET is a new data-handling model that makes it easy to handle data on the Internet. Using Web services. These applications are based on ASP. NET itself will usually tell you what you're doing wrong. All this takes a great deal of effort to get used to.
A dataset is a collection of one or more tables or record sets as well as the relationships between those tables or. Server controls are displayed using HTML. NET uses on your local machine to communicate with local databases. Changes in Web Development The big change in Web development is that you can do it at all. You can bind the controls on a Web form to all kinds of different data sources.
Changes in Data Handling There have been many ways of handling data in previous versions of Visual Basic. The two major types of Web applications are Web forms and Web services.
This means that much of what you know about ADO. It's also what VB. At the heart of ADO. You can also now check the data a user enters into a Web form using validation controls. Things have changed again. Here's an overview: Web forms let you create Web-based applications with user interfaces. Changes in the Visual Basic Language As mentioned earlier.
NET framework. NET now uses namespaces to prevent naming conflicts by organizing classes.
NET is built on a disconnected data model that uses snapshots of data that are isolated from the data source. Visual Basic handles polymorphism with late binding and multiple interfaces. You can now create multithreaded applications. You can now bind any control property to data from a data source. NET Framework to create and manipulate datasets in code. Datasets are based on XML schema.

Inheritance—Inheritance is the process by which you can derive new classes from other classes. Probably the biggest single change is that everything is object oriented now. Polymorphism—Broadly speaking. Here is an overview of what's new in data handling: Data is handled through ADO. You can use the connection wizard or the server explorer to drag and drop whole tables from data sources.
This means you can use and create disconnected. There are many new tools and a wizard for handling data in VB. Abstraction—The ability to create an abstract representation of a concept in code as an object named employee is an abstraction of a real employee.
Encapsulation—This has to do with the separation between implementation and interface. Chapter 12 is all about inheritance in Visual Basic.
You can use the data classes provided in the. You can now create classes that serve as the base class for derived classes. You can import various namespaces to gain access to its classes. That is.
NET in depth: It's all OOP now. The Char data type is an unsigned bit type used to store Unicode characters. And all code has to be enclosed in a class. On the one hand. There are three new data types in VB. NET is now strongly typed. As mentioned above.
Many new concepts have been added to Visual Basic programming as well. The Microsoft. All data items are objects now. Overloading means you can define properties. Here's an overview of some of the changes to the language—there are too many to list them all here.
The Variant type no longer exists. And you can use classes. NET now supports constructors and destructors for use when initializing an object of a specific class. Even integers and other primitive data types are based on this class. VisualBasic namespace gives you access to common Visual Basic keywords like Asc.
The Short data type is a signed bit integer named Integer in earlier Visual Basic versions. Arrays can no longer be 1-based in VB. The data types you can use are now restricted to those in the Microsoft Common Language Specification CLS as we'll see in the next chapter.
There are also changes in the way you declare variables. NET now supports multithreaded applications.
User-defined types are no longer defined with the Type keyword. You can now overload properties. Visual Basic now supports structured exception handling.
In Visual Basic 6. VB6 namespace gives you access to obsolete VB6 keywords such as Open. You use the CType statement to convert between types. ControlChars namespace gives you access to common Visual Basic constants like Cr. English ISBN Be the first to review this item Amazon Best Sellers Rank: Tell the Publisher!
