I'm trying to draw a dot onto an image.
I can do it is asp.NET but nothing is happening when I do the following as part of a Windows Application. An better example would be great.

Any suggestion please?

Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D

Public Class DrawImagewithDot

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

Dim objBitmap As New Bitmap("C:\myIMG.bmp")
Dim g As Graphics = Graphics.FromImage(objBitmap)

Dim redBrush As New SolidBrush(Color.Red)
Dim blueBrush As New SolidBrush(Color.Blue)

g.FillEllipse(blueBrush, 100, 206, 10, 10)

g.FillEllipse(redBrush, 200, 180, 10, 10)

g.DrawImage(objBitmap, 10, 10)

End Sub

End Class
