What is a VB file?

A VB file is a project item file written in the Visual Basic language, an object-oriented programming language created by Microsoft for use with the .NET Framework. It contains Visual Basic instructions in ASCII text format.

More Information

A project item can refer to a variety of Visual Basic project components. Each available project item differs based on whether you are working in a local or web project. Examples of project items include a Windows form, Login form, splash screen, dialog, class, interface, code file, custom control, web custom control, or installer class. The "vb" extension is used for all of these items.

Visual Basic is a programming language implemented on the .NET framework. Visual Basic .NET (VB.NET) was released in 2002 to replace the original Visual Basic language. The VB.NET language is used to create applications based on .NET, such as web applications and XML web services. ".NET" was eventually dropped by Microsoft in 2005 and the VB file is now used by Microsoft Visual Studio.

NOTE: VB files can also be used to contain viruses or other malware. Therefore, do not open VB files if they are an unknown e-mail attachments.

Beam Software is an Australian video game developer that was founded in 1978 and acquired by Krome Studios in 2006, at which point Beam was renamed Krome Studios Melbourne. In the 1990s, Beam produced a handful of games that use their proprietary SIFF file format, including KKND2: Krossfire and The Lost Vikings II.

The SIFF file format can be used to create files that contain both audio and video or just audio. When a SIFF format file contains both audio and video, it is saved using the .vb extension. When it contains just audio, it is saved with the .SON extension.
