如何实现在控件内点击并且移动整个窗体？

[iwangotomars]

程序是窗体上覆盖了一个flash控件，标题栏已经去掉了，现在需要在flash内点击并且拖动窗体任意移动，请问C#该如何实现啊？
谢谢！

如果该flash控件暴露了MouseDown和MouseMove事件则可以挂接这两个事件：
private Point _offset = Point.Empty;
private void FlashMouseDown(MouseEventArgs e)
{
this._offset = e.Location;
}
private void FlashMouseMove(MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
Point location = this.PointToScreen(e.Location);
location.Offset(-this._offset.X, -this._offset.Y);
this.Location = location;
}
}

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsApplication9
{
    
    public partial class Form1 : Form
    {
        [DllImport("user32.dll", EntryPoint = "SendMessage")]
        public static extern int SendMessage(int hWnd, int wMsg, int wParam, int lParam);
        [DllImport("user32.dll", EntryPoint = "ReleaseCapture")]
        public static extern int ReleaseCapture();
        public const int WM_SysCommand = 0x0112;
        public const int SC_MOVE = 0xF012;
        public Form1()
        {
            InitializeComponent();
        }

        private void Flash_MouseDown(object sender, MouseEventArgs e)
        {
            ReleaseCapture();
            SendMessage(this.Handle.ToInt32(), WM_SysCommand, SC_MOVE, 0);
        }
    }
}

private Point m_MousePoint = Point.Empty;
private void FlashMouseDown(MouseEventArgs e)
{
m_MousePoint = e.Location;

}
private void FlashMouseMove(MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this.Location = new Point(this.Location.X - (m_MousePoint.X - e.X), this.Location.Y - (m_MousePoint.Y - e.Y));
}

}

谢谢，问题是Flash控件里面没有找到MouseDown事件啊，没办法将Flash_MouseDown事件捆绑到falsh控件的MouseDown
flash控件是Flash9c.ocx，我试了先加载一个panel，再把flash控件加入到panel，在panel里面捆绑MouseDown事件，但还是不管用
