Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. Dialog boxes with less functionality can be used to provide pop-up capabilities.

Visual Basic can create executables (EXE files), ActiveX controls, or DLL files, but is primarily used to develop Windows applications and to interface database systems.

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. 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. Many attribute values can be modified during run time based on user actions or changes in the environment, providing a dynamic application. Default values are provided when the control is created, but may be changed by the programmer. Controls have attributes and event handlers associated with them. A tool is used to place controls (e.g., text boxes, buttons, etc.) on the form (window). This runtime is included by default in Windows 2000 and later, but for earlier versions of Windows like 95/98/NT it must be distributed together with the executable.ДЇorms are created using drag-and-drop techniques. Performance problems were experienced by earlier versions, but with faster computers and native code compilation this has become less of an issue.ДЄlthough programs can be compiled into native code executables from version 5 onwards, they still require the presence of runtime libraries of approximately 1 MB in size. Since default attributes and actions are defined for the components, a simple program can be created without the programmer having to write many lines of code. Programming in VB is a combination of visually arranging components or controls on a form, specifying attributes and actions of those components, and writing additional lines of code for more functionality.

The language not only allows programmers to create simple GUI applications, but can also develop complex applications. Like the BASIC programming language, Visual Basic was designed to be easily learned and used by beginner programmers.
