当Form的formBorderStyle设为none之后，实现窗体托拽，边框移动窗体的功能。
看了你实现的代码，原贴见http://community.csdn.net/Expert/topic/3401/3401961.xml?temp=.3063928感觉不错，现在我在窗体上加一个label，它的Dock = DockStyle.Top之后窗体的上部，左上角和右上角的边框不能实现移动窗体,请问该如何实现？

这样的话，只能重写一个panel的控件来实现，因为这时panel是当前接爱鼠标事件，当然你可以做成当panel有鼠标事件时让窗体得到，但是重写一个panel控件有时可能更有意思，我没有重写panel，但我重写了一个button的，代码我想只是它们继承的基类不一样罢了：代码大致如下：

明白你的意思了，你可以再加这一句话试试：
private void panel1_Resize(object sender, System.EventArgs e)
{
this.Size = this.panel1.Size;
}

[北京的雾霾天]

还有，就是像你这种情你可以给窗体留出一个＂边＂来，让你的窗体在这个＂边＂上调整窗体的大小位置等．
也就是说你可以不用
this.panel1.Dock = System.Windows.Forms.DockStyle.Fill;来填满整个窗体．而是给你的窗体留出一个可以操作窗体的边来，你也应注意到一个正常的窗体由其是在ＸＰ下看到它是有一个边的，正是这个边才能操作窗体的大小位置，如果把这个边设为None则不能再对它操作了，我想应该是这个道理的．

[hanbinghai]

to hbxtlhx(下着春雨的天)
this.Size = this.panel1.Size这个方法是行不通的
你说给窗体留出一个＂边＂来是没有办法的办法
^_^

要是有更好的办法请发短消息告诉我
结贴了

[北京的雾霾天]

没问题!有好的思路我一定告知.

[北京的雾霾天]

对啊,你那个方法也是可的啊.

[hanbinghai]

不是办法的办法：
可以给窗体添加Panel控件，调整好与form的上下左右的距离，给窗体留出一个＂边＂
效果也不错，^_^

[北京的雾霾天]

问题是怎样来给窗体这个边?
我的一般的做法是得写如下的方法,在里面放上要调整的控件的位置或大小等信息.
protected override void OnLayout(LayoutEventArgs levent)
{
base.OnLayout (levent);
}

[hanbinghai]

对Pannel操作,刚才忘说了，要把panel的Anchor设置为上下左右
this.Panel1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
| System.Windows.Forms.AnchorStyles.Left)
| System.Windows.Forms.AnchorStyles.Right)));

[hanbinghai]

最简单的方法：
新建一个项目，在窗体Load事件中添加
private void Form1_Load(object sender, System.EventArgs e)
{
this.ControlBox = false;
this.Text = string.Empty;
}
就把以上的问题全解决了，就这么简单的两行代码
^_^

[hanbinghai]

问题是怎样来给窗体这个边?
this.DockPadding.Bottom = 2;
this.DockPadding.Left = 2;
this.DockPadding.Right = 2;
this.DockPadding.Top = 2;
真简单啊
