這篇是回應網友問題便測試看看，語言是用C#，有興趣的朋友可以參考看看

using System.Runtime.InteropServices;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        const int WM_SYSCOMMAND = 0x112;
        const int SC_MOVE = 0xF012;

        [DllImport("user32",EntryPoint="ReleaseCapture",CharSet=CharSet.Ansi)] 
        private extern  static int ReleaseCapture ();

        [DllImport("user32",EntryPoint="SendMessageA",CharSet=CharSet.Ansi)] 
        private extern  static int SendMessage (IntPtr  hwnd , int wMsg , int wParam, int lParam ) ;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void Form1_MouseDown(object sender, MouseEventArgs e)
        {
            int i ;
            i = ReleaseCapture();
            i = SendMessage(this.Handle , WM_SYSCOMMAND, SC_MOVE, 0);
        }
    }
}
