A VB file is a source code file created in Visual Basic language that was created by Microsoft for development of .NET applications. Another similar language with different syntax is C# whose files are saved with .CS file extension. The file format provides the low-level programming language for writing code that is compiled to generate the final output file in the form of EXE or a DLL. These can be created and compiled with Microsoft Visual Studio. Microsoft Visual Studio Express can also be used to create and update such files which is a free IDE. A simple Visual Studio project solution created with VB language can comprise of one or more such files. Files marked for inclusion in compilation are listed in the CSPROJ file which is part of the project and tells compiler to use the marked files.

  • Variables declaration - To declare class level variables for the particular implementation
  • Methods Declaration - To declare methods declaration for the particular functionality


Imports System

  Sub Main()
      Console.WriteLine("Hello World")
  End Sub
End Module
