VB.net Module

In this tutorial,we cover how to create a module,store information inside a module and then access that information in your application. A module can be used to store functions,subs or even variables to sort out your code so that you can access things more easily. If you have a sophisticated application where you have to store a lot of functions,subs or variables then it would be useful to sort them into different categories using modules. A module is differen t to a class because all of the members of a module are shared and a module does not have a consutrctor,meaning you can not create an instance of a module.

Module Code

Module functions

    Public bla As Integer = 10
    Public bla2 As Integer = 20

    Public Function addnumbers(ByVal number1 As Integer,ByVal number2 As Integer)
        Return number1 + number2
    End Function

End Module

Code

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles Button1.Click
        TextBox3.Text = addnumbers(bla,bla2)
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles Button2.Click
        MessageBox.Show(addnumbers(TextBox1.Text,TextBox2.Text))
        MessageBox.Show(functions.addnumbers(TextBox1.Text,TextBox2.Text))
    End Sub

End Class
