This tutorial will teach you how to create a zoom application in vb.net. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Have only a Timer on the Form named Timer1. 3. Now, we will code our program. We will declare first the variables. This will have the Graphics library and the bitmap that we will use. 
  1.     Dim g As Graphics = Me.CreateGraphics
  2.  
  3.     Dim bmp As Bitmap
Then after that we will code for the Tick event of the Timer. This will totally create image out from the mouse hovering to zoom the location of the mouse cursor. 
  1.     Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
  2.         bmp = New Bitmap(250, 200)
  3.         g = Graphics.FromImage(bmp)
  4.         g.CopyFromScreen(MousePosition.X - 100, MousePosition.Y - 10, 0, 0, New Size(300, 300))
  5.         PictureBox1.Image = bmp
  6.     End Sub
Lastly, start the Timer from your Form_Load. 
  1.     Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  2.         Timer1.Start()
  3.     End Sub
