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
