Centering Child MDI Forms

Does anyone know how to center a Child MDI form within its parent ? The startup property doesn't work.

Code:

---

Private Sub MDIForm_Load()
    Form1.Move (Me.ScaleWidth / 2) - (Form1.Width / 2), (Me.ScaleHeight / 2) - (Form1.Height / 2)
End Sub

---

Or you can place it in the Form you want to load:

Code:

---

Private Sub Form_Load()
    Move (MDIForm1.ScaleWidth / 2) - (Me.Width / 2), (MDIForm1.ScaleHeight / 2) - (Me.Height / 2)
End Sub
