MultiThreading in vb.net

In this tutorial, we cover the concept of MultiThreading. Multi Threading allows an application to run different bits of code at the same time without causing your User Interface to become unresponsive. Simply run two programs simultaneously not wait for complete one program to another one. This tutorial will hopefully explain the concept of multithreading to you and we will continue with delegates in the next tutorial.

Copy and paste below Code:

Public Class Form1

    Dim i As Integer

    Dim i2 As Integer

    Dim thread As System.Threading.Thread

    Dim thread2 As System.Threading.Thread

    Private Sub countup()

        Do Until i = 10000

            i = i + 1

            Label1.Text = i

            Me.Refresh()

        Loop

    End Sub

    Private Sub countup2()

        Do Until i2 = 10000

            i2 = i2 + 1

            Label2.Text = i2

            Me.Refresh()

        Loop

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        thread = New System.Threading.Thread(AddressOf countup)

        thread.Start()

    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        thread2 = New System.Threading.Thread(AddressOf countup2)

        thread2.Start()

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Me.CheckForIllegalCrossThreadCalls = False

    End Sub

End Class
