ciscenje PictureBox1 vb 2010

vb2010
run-time
Dim lblAuto As New Label
Me.PictureBox1.Controls.Add(lblAuto)
lblAuto.Font = New Font("Arial", 7, FontStyle.Regular)
lblAuto.Text = "text"
lblAuto.Location = New Point(0, 10)
lblAuto.Size = New Size(17, 17)
lblAuto.BackColor = Color.LightCoral

interesuje me kako mogu da ocistim kontrolu PictureBox1
koju sam postavio u dizain modu, pa da opet nesto crtam u navedenoj kontroli

ne pomaze:
Me.PictureBox1.Refresh()
Me.PictureBox1.Image = Nothing

Jesi li probao pre ovog Nothing ubaciti
PictureBox1.Image.Dispose() ?
Pozdrav
