public partial class MsgForm : Form
{
　　　　　　　 [DllImport("coredll.dll", EntryPoint = "RegisterWindowMessage", SetLastError = true)]
　　　　　　　 private static extern uint RegisterWindowMessage(string lpString);
　　　　　　　 private uint msgUid = RegisterWindowMessage ("MESSAGE_UID");

　　　public static int MSG_BROADCAST = 0xFFFF;
　　　
　　　private void SendMessage(object sender)
　　　　　　　 {
　　　　　　　　　　　 Message msg = Message.Create((IntPtr) MSG_BROADCAST, (int)msgUid , IntPtr.Zero, IntPtr.Zero);
　　　　　　　　　　　 MessageWindow.SendMessage(ref msg);
　　　　　　　 }
