Visual Basic - Form transparente

Hay alguna manera de hacer que el form sea transparente? O sea que solamente se vean los controles dentro de el?

Saludos

'Llamar a la Funcion RecortarVentana en Form_Load
Private Type POINTAPI
X As Long
Y As Long
End Type

Private Declare Function CreatePolygonRgn Lib "gdi32" (lpPoint As POINTAPI, ByVal nCount As Long, ByVal nPolyFillMode As Long) As Long
Private Declare Function Polygon Lib "gdi32" (ByVal hdc As Long, lpPoint As POINTAPI, ByVal nCount As Long) As Long
Private Declare Function SetWindowRgn Lib "user32" (ByVal hWnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long

Private Sub RecortarVentana()
On Error Resume Next
Dim Xpuntos As Variant
Dim Puntos() As POINTAPI
Dim NroPtos As Integer
Dim Handle As Long

Xpuntos = VBA.Array(20, 78, 53, 20, 80, 76, 11, 36, 82, 36)
NroPtos = 5
ReDim Preserve Puntos(NroPtos - 1)

For i = 0 To NroPtos - 1
Puntos(i).X = Xpuntos(i * 2)
Puntos(i).Y = Xpuntos((i * 2) + 1)
Next

Handle = CreatePolygonRgn(Puntos(0), NroPtos, 1)
SetWindowRgn Me.hWnd, Handle, 1
End Sub

Private Sub Form_Load()
RecortarVentana
End Sub

Me viene barbaro, gracias. Pero los controles dentro del Form tambien desaparecen
