#region -- 類方法說明
/* 說明:
*
* 1.名稱空間: Apc_AniWindow
*    類名    : AniWindow
*
*   2.宣告: AniWindow a=new AniWindow(this.Handle,6,1,this);
*
* 3.引數說明:AniWindow(視窗控制程式碼,動畫樣式,開啟或關閉標誌,例項表單);
*    視窗控制程式碼: this.Handle
*    動畫樣式: 0 -> 普通顯示
*     1 1 -> 從左向右顯示
*      2 -> 從右向左顯示
*      3 -> 從上到下顯示
*      4 -> 從下到上顯示
*      5 -> 透明漸變顯示
*      6 -> 從中間向四周
*      7 -> 左上角伸展
*      8 -> 左下角伸展
*      9 -> 右上角伸展
*      10 -> 右下角伸展
*    開關標誌: 0為關閉視窗 1為開啟視窗
*    例項表單: 為了去除Label的BUG, 取值 this
