public static class SystemMenuExtendMethod
{
    //以下為api函式
    [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
    public static extern bool SetWindowText(IntPtr hwnd, String lpString);
 
    [DllImport("user32.dll", EntryPoint = "FindWindow")]
    public static extern int FindWindow(string lpClassName,
          string lpWindowName);
 
    //變更目標視窗的TITLE
    public static void SetWindowText(string titlename ,string titlemsg)
    {
        //SetWindowText(form.Handle, title);
        Process[] processes = Process.GetProcesses();
        List windowHandles = new List();
        foreach (Process process in processes)
        {
            if (process.MainWindowTitle == titlename)
            { 
                 //windowHandles.Add(process.Handle);
                SetWindowText((IntPtr)_processname, titlemsg);
                break;
            }
       }
    }  
 
    //變更自己本身的TITLE
    public static void SetThisWindowText(Form form, string titlemsg)
    {
        SetWindowText(form.Handle, titlemsg);
    }
    int _processname = FindWindow(process.MainProcessName.ToString(), null);
