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 FunctionEnd 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 SubEnd Class
