Membuat Form berbentuk Oval atau shape

Buat sebuah Form baru (BorderStyle=None), lalu di bagian '(Declarations)'-nya ketikkan :

Private Declare Function CreateRoundRectRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long, ByVal X3 As Long, ByVal Y3 As Long) As Long
Private Declare Function CreateEllipticRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long) As Long
Private Declare Function SetWindowRgn Lib "user32" (ByVal hwnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long

Untuk membuat Form berbentuk shape rounded rectangle, di bagian 'Form_Load' ketikkan :

Dim l As Long
l = CreateRoundRectRgn(0, 0, Me.Width / Screen.TwipsPerPixelX, Me.Height / Screen.TwipsPerPixelY, 20, 20)
SetWindowRgn Me.hwnd, l, False

Sedangkan untuk membuat Form berbentuk shape oval / lingkaran, di bagian 'Form_Load' ketikkan :

Dim l As Long
l = CreateEllipticRgn(0, 0, Me.Width / Screen.TwipsPerPixelX, Me.Height / Screen.TwipsPerPixelY)
SetWindowRgn Me.hwnd, l, False
