So in chapter 1, you learn the basic techniques for working in the Visual Basic development environment.
Then, in chapter 2, you learn how to use this environment as you develop your first Visual Basic application.
Next, chapters 3, 4, and 5 present the essentials of the Visual Basic language that you will use as you develop your applications. Then chapter 6 shows you how to create and use your own classes as you develop applications. And chapter 7 presents the features that help you test and debug more complex applications. NET programming.
NET, you need to become familiar with the. Introduction to the. NET The.
NET applications and the services you can use within those applications. One of the main goals of this framework is to make it easier to develop applications that run over the Internet. However, this framework can also be used to develop traditional business applications that run on the Windows desktop. To develop a Visual Basic.
NET application, you use a product called Visual Studio. This is actually a suite of products that includes the three programming languages described in figure Finally, more advanced topics such as Visual Basic object oriented programming, database access and graphics drawing are detailed.

Book Description Visual Basic Essentials is intended to be of use to both novices looking to learn Visual Basic, and to those proficient in other languages that plan to cross-train from other programming languages.
Prior to launching Payload Media, Neil held a number of positions in the IT industry including programming, web development, systems administration and sales and marketing and is the author of a number of technology related books.

NET uses round brackets to define the parameters of subroutines or functions.
A single quotation mark ' or the keyword REM, placed at the beginning of a line or after any number of space or tab characters at the beginning of a line, or after other code on a line, indicates that the remainder of the line is a comment. Simple example[ edit ] The following is a very simple VB.
WriteLine "Hello, World! Each line serves a specific purpose, as follows: Module Module1 This is a module definition. Modules are a division of code, which can contain any kind of object, like constants or variables, functions or methods, or classes, but can't be instantiated as objects like classes and cannot inherit from other modules.
Modules serve as containers of code that can be referenced from other parts of a program. Sub Main It defines a subroutine called "Main".
WriteLine "Hello, world! Console is a system object, representing a command-line interface also known as "console" and granting programmatic access to the operating system's standard streams. The program calls the Console method WriteLine, which causes the string passed to it to be displayed on the console.
Instead of Console. WriteLine, one could use MsgBox, which prints the message in a dialog box instead of a command-line window. Do Until Integer. ReadLine with a version which takes a prompt string. NET should be considered as just another version of Visual Basic or a completely different language is a topic of debate. There are new additions to support new features, such as structured exception handling and short-circuited expressions.
Also, two important data-type changes occurred with the move to VB. NET: compared to Visual Basic 6, the Integer data type has been doubled in length from 16 bits to 32 bits, and the Long data type has been doubled in length from 32 bits to 64 bits.
This is true for all versions of VB. A bit integer in all versions of VB.
NET is now known as a Short. Similarly, the Windows Forms editor is very similar in style and function to the Visual Basic form editor. The things that have changed significantly are the semantics—from those of an object-based programming language running on a deterministic , reference-counted engine based on COM to a fully object-oriented language backed by the.
NET Framework , which consists of a combination of the Common Language Runtime a virtual machine using generational garbage collection and a just-in-time compilation engine and a far larger class library. The increased breadth of the latter is also a problem that VB developers have to deal with when coming to the language, although this is somewhat addressed by the My feature in Visual Studio The changes have altered many underlying assumptions about the "right" thing to do with respect to performance and maintainability.
Some functions and libraries no longer exist; others are available, but not as efficient as the "native".
