From some of my .Net forms
 Code:
$OF = $system.OpenFileDialog()
$OF.DefaultExt = "sav"
$OF.Filter = "Saved Prefs(*.sav)|*.sav"
$OF.InitialDirectory = $DefaultPath
$OF.Title = "Save Preferences"
$OF.AddExtension = "True"
$OF.RestoreDirectory = "True"
;Read the saved file and fill out the arrays accordingly
If $OF.ShowDialog = 1
	$Path = $OF.Filename
