It depends. If you assigned an image to the Image property, assign
Nothing. If you paint anything in the Paint event (/onpaint), call
picture1.invalidate and stop painting in the paint event.

You can use the 'Clear' method of your 'Graphics' object.

\\\
Private m_Clear As Boolean

Public Sub OnPaint(ByVal e As PaintEventArgs)
If m_Clear Then
e.Graphics.Clear(Me.BackColor)
Else
e.Graphics.*
End If
End Sub

Private Sub Clear()
m_Clear = True
Me.Invalidate()
End Sub

Private Sub DrawAgain()
m_Clear = False
Me.Invalidate()
End Sub
