VB.Net怎么做圆形窗体

设置Region属性：

Dim path As New System.Drawing.Drawing2D.GraphicsPath

path.AddEllipse(0, 0, 400, 300)

Region = New Region(path)

如何在vb.net中创建圆角窗体

如下所示：

Private Sub Type(ByVal sender As Control, ByVal p_1 As Integer, ByVal p_2 As Double)

Dim oPath As New Drawing2D.GraphicsPath()

oPath.AddClosedCurve(New Point() {New Point(0, sender.Height / p_1), New Point(sender.Width / p_1, 0), New Point(sender.Width - sender.Width / p_1, 0), New Point(sender.Width, sender.Height / p_1), New Point(sender.Width, sender.Height - sender.Height / p_1), New Point(sender.Width - sender.Width / p_1, sender.Height), _

New Point(sender.Width / p_1, sender.Height), New Point(0, sender.Height - sender.Height / p_1)}, CSng(p_2))

sender.Region = New Region(oPath)

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Type(Me, 20, 0.1)

End Sub
