6.0 / 1998; 21 years ago ( 1998), and Website Major Influenced by Influenced,,, and Visual Basic is a from for its (COM) programming model first released in 1991 and declared during 2008. Microsoft intended Visual Basic to be relatively easy to learn and use. Visual Basic was derived from and enables the of applications, access to using,, or, and creation of controls and objects. A programmer can create an application using the provided by the Visual Basic program itself. Over time the community of programmers developed third-party components.

Programs written in Visual Basic can also use the, which requires external function declarations. The final release was version 6 in 1998 (now known simply as Visual Basic). On April 8, 2008, Microsoft stopped supporting Visual Basic 6.0. The Microsoft Visual Basic team still maintains compatibility for Visual Basic 6.0 applications on, including R2,,,,,,, and through its 'It Just Works' program.

In 2014, some still preferred Visual Basic 6.0 over its successor,. In 2014 some developers lobbied for a new version of the VB6 programming environment. In 2016, Visual Basic 6.0 won the technical impact award at The 19th Annual D.I.C.E. A dialect of Visual Basic, (VBA), is used as a macro or scripting language within several Microsoft applications, including. Contents • • • • • • • • • • • • • Language features [ ] Like the programming language, Visual Basic was designed for an easy. Programmers can create both simple and complex applications.

Programming in VB is a combination of visually arranging or on a, specifying attributes and actions for those components, and writing additional lines of for more functionality. Since VB defines default attributes and actions for the components, a programmer can develop a simple program without writing much code. Programs built with earlier versions suffered performance problems, but faster computers and native code compilation has made this less of an issue. [ ] Though VB programs can be compiled into native code executables, they still require the presence of around 1 MB of runtime libraries.

Core runtime libraries are included by default in and later, but extended runtime components still have to be installed. Earlier versions of (95/98/NT), require that the runtime libraries be distributed with the executable. An empty form in Visual Basic 6 Forms are created using techniques. A tool is used to place controls (e.g., text boxes, buttons, etc.) on the form (window). Controls have and associated with them.

Default values are provided when the control is created, but may be changed by the programmer. Many attribute values can be modified during run time based on user actions or changes in the environment, providing a dynamic application. For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc.

By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or even prevent certain characters from being inserted. Visual Basic can create executables (EXE files),, or DLL files, but is primarily used to develop Windows applications and to interface database systems. Dialog boxes with less functionality can be used to provide pop-up capabilities. Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. For example, a drop-down combination box automatically displays a list. When the user selects an element, an event handler is called that executes code that the programmer created to perform the action for that list item. Alternatively, a Visual Basic component can have no user interface, and instead provide ActiveX objects to other programs via (COM).

This allows for processing or an add-in module. The runtime recovers unused memory using, which depends on variables passing out of scope or being set to Nothing, avoiding the problem of that are possible in other languages.

There is a large library of utility objects, and the language provides basic support for. Unlike many other programming languages, Visual Basic is generally not case-sensitive—though it transforms into a standard case configuration and forces the case of variable names to conform to the case of the entry in the symbol table.
