有很多让你意想不到的功能。要创建特殊的不规则窗口看上去似乎很难。但我们如果我们说我们用
几行代码就可以实现，这似乎不可思议。但事实就是如此！请试试：
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
Private Sub Form_Load()
Show The form!
SetWindowRgn hWnd, CreateEllipticRgn(0, 0, 300, 200), True
End Sub
上述代码可以创建一个椭圆形状的窗口。
