特殊类型窗体制作: 制作可以飘动的窗体

原理: (这里演示纵坐标不变的窗体移动), 两个 timer, 一个控制从左至右, 到达预先设定的点时触发另一个 timer,

        当然另一个 timer 控制从右至左的移动( 其实质是横坐标的变化)

        如果你希望上下左右或斜线移动甚至乱七八糟(呵呵, 应该叫随机)只要加足够的 timer 并控制好横纵坐标的变换即可.

            //窗体的左上角横坐标随着timer1不断加一
            Point p = new Point(this.DesktopLocation.X + 1, this.DesktopLocation.Y);
            this.DesktopLocation = p;
            if (p.X == 630)
            {
                timer1.Enabled = false;
