It's one of the robust, feature-rich online compilers for VB.net language, running on the latest version 16. Getting started with the OneCompiler's VB.net compiler is simple and pretty fast. The editor shows sample boilerplate code when you choose language as VB.net. OneCompiler also has reference programs, where you can look for the sample code to get started with.
OneCompiler's VB.net online editor supports stdin and users can give inputs to programs using the STDIN textbox under the I/O tab. Following is a sample VB.net program which takes name as input and prints hello message with your name.
Public Module Program
Public Sub Main(args() As string)
Dim name as String = Console.ReadLine() ' Reading input from STDIN
Console.WriteLine("Hello " & name) ' Writing output to STDOUT

Visual Basic is a event driven programming language by Microsoft, first released in the year 1991.
Variable is a name given to the storage area in order to identify them in our programs.
Simple syntax of Variable declaration is as follows
Dim variableName [ As [ New ] dataType ] [ = initializer ]
variableName = value

Procedure is a sub-routine which contains set of statements. Usually Procedures are written when multiple calls are required to same set of statements which increases re-usuability and modularity.
Procedures are of two types.
Functions return a value when they are called.
[accessModifiers] Function functionName [(parameterList)] As returnType
'code
End Function
Sub-procedures are similar to functions but they don't return any value.
Sub ProcedureName (parameterList)
'Code
End Sub
