窗口打开关闭的动画效果

[skysquall]

我想用计时器控制窗口位置及高宽来自己实现动画，实现那种关闭时收缩的效果，但是发现当调用this.close()时会有一个黑线框一闪而过，很难看，有没有人知道这个黑线框怎么来的？以及怎么把它去掉？

提个思路，大家看看可不可以，加一个time，关闭窗口时，先不关闭，定时缩小窗口的大小，窗口的位置不变，当窗口大小为一个比较小的数值时，再关闭窗口。

你收缩到高度为0和宽度都为0时，再this.Close()看看
或者收缩到一定小时，把窗体的标题栏设置None，即FormBorderStype=None看看

[skysquall]

高度为0和宽度都为0时，再this.Close()，还是有黑线框
FormBorderStype=None，本来窗口就是无边的窗口

[gxingmin]

我测试没有黑线框啊

 private void timer1_Tick(object sender, EventArgs e)
        {
            this.Width -= 10;
            this.Height -= 10;

            if (this.Width < 50 || this.Height < 50)
            {
                this.Width = 0;
                this.Height = 0;
                this.Close();
            }

        }

LZ有使用到不规则的皮肤么？我以前在做一个类似QQ弹出窗口的时候因为用了不规则的窗口导致出现下面一条黑线（静止窗口不会出现，只出现在运动窗口中）

我是在wince上跑的Form，所以可能不一样，windows上黑线框看不出来好像，wince上就能看出来
