ProgressBar using timer

In this blog we will know about progressbar control and timer control. We must have noticed while installing certain software programs a progressbar goes on increasing and time goes on decreasing simultaneously.




Public Class Form1

    Inherits System.Windows.Forms.Form

    Dim i As Integer = 0

    Dim j As Integer = 0

#Region " Windows Form Designer generated code "


    Public Sub New()



        'This call is required by the Windows Form Designer.



        'Add any initialization after the InitializeComponent() call


    End Sub


    'Form overrides dispose to clean up the component list.

    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

        If disposing Then

            If Not (components Is Nothing) Then


            End If

        End If


    End Sub


    'Required by the Windows Form Designer

    Private components As System.ComponentModel.IContainer


    'NOTE: The following procedure is required by the Windows Form Designer

    'It can be modified using the Windows Form Designer. 

    'Do not modify it using the code editor.
