哎，粘了这么长的代码，不知道什么意思~！接分

[平生我自如]

代码有点长了！你加点描述就好了！

这段有问题

[hhc123]

[DllImport("user32.dll")] 
  public static extern bool ReleaseCapture(); 
[DllImport("user32.dll")] 
  public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam); 
  public const int WM_SYSCOMMAND = 0x0112; 
  public const int SC_MOVE = 0xF010; 
  public const int HTCAPTION = 0x0002; 
 private void button1_MouseDown(object sender, MouseEventArgs e)
        {
            ReleaseCapture(); 
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0); 

        }

这是无边框拖动

发的东西很好 很完整 放到VS2008里新建一个窗体就行了 就能看到是什么意思 就是
//SetWindowLong(new HandleRef(this, this.Handle), -16, GetWindowLong(new HandleRef(this, this.Handle), -16) | WS_SYSMENU); //这里加上这段后 下面的case WM_NCHITTEST:就没反应了 请问这儿怎么写
这段有问题
把注释去掉 就不能响应case WM_NCHITTEST: 的功能了

[renyibin]

hhc123 你的我试过了 不好用
private void Form12_MouseDown(object sender, MouseEventArgs e)
{
ReleaseCapture();
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
}

学习。。。

有没有牛人可以解决这个问题啊？
急！！！
呵呵~

[wtin008]

同求答案。。加上任务栏左右键功能后不能改变大小，可以改变大小的时候却不能使用任务栏左右键功能。。
