The latest version of Microsoft's Visual Studio, called Visual Studio , the projects using Visual Basic Express Edition and Visual Web Developer. Programming Visual Dave Grundgeiger. Publisher: O'Reilly Published just in time for the first release of Visual Basic tools for creating and consuming web services -- vendor-independent software services that.

Web Editor: a drag-and-drop approach to creating webpages. Class Designer: a visual based tool for creating new classes. Database tools: a graphical tool for creating database schemas. There are many other parts that can be used with Visual Studio. Of particular interest is Team Explorer , which allows different programmers using Visual Studio to collaborate using the Microsoft revision control system. Most people without any programming experience can figure out what it does. But even during that time, things were changing. Gone were the line numbers, in were real functions. But this was the tail end of the technology trend. Visual Basic Visual Basic changed all that. It came out in It seems that Microsoft had originally thought of it as a hobbyist language — even if a far more cool one than those that had come before. At first, it was used as something of a semi-professional tool by people in small businesses who needed specialized software. By , Microsoft released VBScript, which allowed people to automate things like Office applications — a great improvement over traditional macro languages. And then things really changed.

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". NET alternatives. Even if they compile, most converted Visual Basic 6 applications will require some level of refactoring to take full advantage of the new language. Documentation is available to cover changes in the syntax, debugging applications, deployment and terminology. NET syntax. They assume that the developer has created a form, placed a button on it and has associated the subroutines demonstrated in each example with the click event handler of the mentioned button.

Each example creates a "Hello, World" message box after the button on the form is clicked. NET automatically generate the Sub and End Sub statements when the corresponding button is double-clicked in design view. It starts at the beginning and covers everything. It is also available in and editions.

Tools Visual Studio provides all the tools that you would normally need. But there are various add-ons and extensions that you might find useful under some circumstances.

Visual Basic 6 Quick Reference : a basic reference on a single sheet of paper — handy for pinning to the wall. MZ-Tools : a commercial Visual Studio add-on that offers customizable code templates, specialized designers, and much more.

It was designed and released in the mids, primarily as a light-weight scripting language for use in Microsoft environments. It was also intended early on as an in-browser language, as an alternative to JavaScript. They were both targeted primarily at web developers initially. Also, the language expanded, to include regular expressions, object-oriented programming principles, and other advanced features.

By version 5 of the language, it was capable of doing just about anything other major languages were capable of. With the advent of the. Due to its inclusion in.

Interestingly, for as much as VBScript has expanded its reach over the last two decades, there is one place where it is no longer available: the browser. VBScript was never available in non-Microsoft browsers. However, most VB script usage falls into a small handful of categories: Systems administration: administrators of various Microsoft systems were among the first adopters of VBScript, as it was a marked improvement over earlier alternatives. It continues to be used by sysadmins, and its use is somewhat analogous to the use of Bash or Perl among Linux administrators.

VBScript and Web Development VBScript was originally targeted at web developers, both for client-side in-browser and server-side scripting. Even though in-browser use has been scant and is no longer supported , the browser-based features of VBScript can be exploited in the context of HTML Application, a Windows app format that allows a desktop UI to be built in HTML and powered via one or more scripting languages.

This approach is fairly popular among Windows sysadmins and developers, as it allows them to get a prototype up and running pretty fast.

Features VBScript is primarily a functional language. It supports classes and objects, but not dogmatically so. Early versions of the language did not support classes and other object-oriented features.

Standard logic and control-flow structures are available, as are a wide variety of data types. There are function procedures and sub procedures. Sub procedures do not return a value, but can perform actions. Environment VBScript has to be run in a supported environment. For server-side web development, that environment is ASP. For systems automation, it is usually the Windows Script Host. VBScript syntax looks a little bit like JavaScript, but there are enough differences that it can be easy to get tripped up.

Variables should be declared using the dim keyword before they are used. You can specify the variable type, or leave it undefined until a value is assigned.
