 2.using System.Collections.Generic; 
 3.using System.ComponentModel; 
 4.using System.Data; 
 5.using System.Drawing; 
 6.using System.Text; 
 7.using System.Windows.Forms; 
 8.using System.Runtime.InteropServices; 
 9.namespace WindowsApplication1 
 10.{    
 One. Public partial class Form1:form 
 12.        {
 Form1 () 
 14. {
 InitializeComponent ();        
 17} 
. [DllImport ("user32.dll", EntryPoint = "SendMessage")] 
. public static extern int SendMessage (int hWnd, int wmsg, int wParam, int lParam);         
 [DllImport ("user32.dll", EntryPoint = "ReleaseCapture")] 
 20. public static extern int releasecapture (); 
. public const int wm_syscommand = 0x0112; 
. public const int sc_move = 0xf012; 
. 
. 
 private void Form1_mousedown (object sender, MouseEventArgs e) 
26. {
 ReleaseCapture (); 
 SendMessage (this. Handle.toint32 (), Wm_syscommand, Sc_move, 0); 
.} 
 
        private void Form1_Load (object sender, EventArgs e) 
 32.        {
 A. 
 34.    } 
 35. 
.} 

Method Two:

11.
         protected   override   void  WndProc (ref message  m)
        {
             base. WndProc (ref  m);  If  (m.msg = = 0x84)
            {
                 Switch  (M.result.toint32 ())
                {
Case  1:
19.
                        M.result =  new  IntPtr (2);  break;
