如何创建一个圆角的矩形窗体？
我想制作一个圆角的矩形窗体，用了以下的代码，但不能实现矩形的四个角为圆角，只有左上角是圆角。请教大家：如何创建一个圆角的矩形窗体？谢谢!
Private Declare Function SetWindowRgn Lib "user32" (ByVal Hwnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long
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 DeleteObject Lib "gdi32" (ByVal hObject As Long) As Long
Private Sub Form_Load()
Dim FormWidth As Long
Dim FormHeight As Long
FormWidth = Me.Width
FormHeight = Me.Height
'形状
Dim Round
Round = CreateRoundRectRgn(0, 0, FormWidth, FormHeight, 50, 50)
Round = SetWindowRgn(Me.Hwnd, Round, True)
DeleteObject Round
End Sub
这个问题，我在VBA论坛中问过，答案是：可能是VB和VBA中的尺寸的换算单位不同所致。但没有给出最终的解决方案，所以来这里求教?
