MDI child question

Can you center an mdichild form ? if so how because i can't get the form to center.

VB Code:

Form1.Left = Me.ScaleWidth / 2 + Form1.Width / 2
Form1.Top = Me.ScaleHeight / 2 + Form1.Height / 2
Form1.Show

This will center the form, normally u can use the CenterOwner option, but that doesent work with MDi ;/
