Visual Basic is derived from the BASIC programming language. With its graphical user interface (GUI) and rapid Application development (RAD) system, VB can easily connect to databases using DAO, RDO, ADO, or easily create Active X controls for efficient generation of type-safe and object-oriented applications. Programmers can easily use the components provided by VB to quickly build an application.

In summary, Visual Basic has the following characteristics:

  • Visual design platform
  • Event-driven programming mechanism
  • It is a modular and structured programming language
  • It has powerful database function
  • Rich ActiveX technology
  • Powerful network features

In Visual Basic, attributes, methods, and events can be used to describe and measure the characteristics of an object. In addition, a lot of controls related to form projects are used in Visual Basic development. However, Visual Basic language has three obvious shortcomings, such as no support for inheritance, no native support for multithreading, and imperfect exception handling, which make it limited (these shortcomings have been improved in vb.NET).
