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()

MyBase.New()

'This call is required by the Windows Form Designer.

InitializeComponent()

'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

components.Dispose()

End If

End If

MyBase.Dispose(disposing)

End Sub

'Required by the Windows Form Designer

Private components As System.ComponentModel.IContainer
