Sorry but your code is not clear to me, try this:
[code]
Public Sub Form_Open()

  Dim hWindow As Window

  Application.MainWindow = Me
  With Me
    .Width = 420
    .Height = 420
    .Center
    .Title = "MAIN WINDOW"
  End With
  For i As Integer = 0 To 9
    With hWindow = New Window As "Form" & CStr(i + 1)
      .X = i * 50
      .Y = i * 50
      .Width = 420
      .Height = 420
      .Title = "FORM " & CStr(i + 1)
      .Show
    End With
  Next

End
[/code]
