VB.NET用双缓冲解决listview闪烁问题

添加一个类，第二个效果更好，然后修改 Form1.Designer.vb

 如果修改程序集名称的话，先F5调试程序，然后就可以打开Form1窗口了。

Public Class DoubleBufferListView
    Inherits System.Windows.Forms.ListView
    Public Sub DoubleBufferListView()
        SetStyle(ControlStyles.OptimizedDoubleBuffer Or ControlStyles.AllPaintingInWmPaint, True)
        SetStyle(ControlStyles.EnableNotifyMessage, True)
    End Sub
    Protected Overrides Sub OnNotifyMessage(ByVal m As Message)
        If (m.Msg <> &H14) Then
            MyBase.OnNotifyMessage(m)
        End If
    End Sub
End Class

Public Class DoubleBufferListView
    Inherits System.Windows.Forms.ListView
    Public Sub New()
        MyBase.New()
        DoubleBuffered = True
    End Sub
End Class
