如图，我有一个无边框窗体，上面有2个控件，我重写了WndProc，但是鼠标在panel和tabcontrol上移动，窗体的WndProc捕获不到，也就不能改变和拖动大小，这是我的窗体代码
protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case ImportFromDLL.WM_COPYDATA:
var copyData = (ImportFromDLL.COPYDATASTRUCT)m.GetLParam(typeof(ImportFromDLL.COPYDATASTRUCT)); //获取数据
//MessageBox.Show(copyData.lpData);
base.WndProc(ref m); //todo 接受到消息后做一些事情
break;
case 0x0084:
base.WndProc(ref m);
Point vPoint = new Point((int)m.LParam & 0xFFFF,
(int)m.LParam >> 16 & 0xFFFF);
vPoint = PointToClient(vPoint);
if (vPoint.X <= 5)
if (vPoint.Y <= 5)
m.Result = (IntPtr)Win32.Guying_HTTOPLEFT;
else if (vPoint.Y >= ClientSize.Height - 5)
m.Result = (IntPtr)Win32.Guying_HTBOTTOMLEFT;
else m.Result = (IntPtr)Win32.Guying_HTLEFT;
else if (vPoint.X >= ClientSize.Width - 5)
if (vPoint.Y <= 5)
m.Result = (IntPtr)Win32.Guying_HTTOPRIGHT;
else if (vPoint.Y >= ClientSize.Height - 5)
m.Result = (IntPtr)Win32.Guying_HTBOTTOMRIGHT;
else m.Result = (IntPtr)Win32.Guying_HTRIGHT;
else if (vPoint.Y <= 5)
m.Result = (IntPtr)Win32.Guying_HTTOP;
else if (vPoint.Y >= ClientSize.Height - 5)
m.Result = (IntPtr)Win32.Guying_HTBOTTOM;
break;
case 0x0201: //鼠标左键按下的消息
m.Msg = 0x00A1; //更改消息为非客户区按下鼠标
m.LParam = IntPtr.Zero; //默认值
m.WParam = new IntPtr(2);//鼠标放在标题栏内
base.WndProc(ref m);
break;
default:
base.WndProc(ref m);
break;
}
}
有一条106，238，255颜色的线，贼难看
