從前,總是使用雙重緩衝,但是這方法不管用,閃爍還是嚴重!自從stackoverflow找到一個很棒的方法後!非常有效!僅此作為筆記。

protected override CreateParams CreateParams {
  get {
    CreateParams cp = base.CreateParams;
    cp.ExStyle |= 0x02000000;  // Turn on WS_EX_COMPOSITED
    return cp;
  }
}
Protected Overrides ReadOnly Property CreateParams() As CreateParams
    Get
        Dim params As CreateParams = MyBase.CreateParams
        params.ExStyle = params.ExStyle Or &H2000000
        Return params
    End Get
End Property
