Here is the sample code to draw circle with point and radius. Using this function, you can draw centre and full circle based on the screen resolution.

VB

Private Sub DrawCircle(ByVal cp As Point, ByVal radius As Integer)
      Dim gr As Graphics
      gr = Panel1.CreateGraphics
      Dim rect As Rectangle = New Rectangle(cp.X - radius, cp.Y - radius, 2 * radius, 2 * radius)
      gr.DrawEllipse(Pens.Black, rect)

  End Sub
