怎么获取win7上没显示在任务栏上的图标（隐藏的托盘图标）

如何获取win7上没显示在任务栏上的图标（隐藏的托盘图标）？
通过下面的代码，可以得到显示在任务栏上的图标，隐藏的图标如何取得？

private static IntPtr GetTrayPointer()
  {
  IntPtr h = IntPtr.Zero;
  IntPtr hTemp = IntPtr.Zero;

  h = Win32API.FindWindow("Shell_TrayWnd", null); 
  h = Win32API.FindWindowEx(h, IntPtr.Zero, "TrayNotifyWnd", null);
  h = Win32API.FindWindowEx(h, IntPtr.Zero, "SysPager", null);

  hTemp = Win32API.FindWindowEx(h, IntPtr.Zero, "ToolbarWindow32", null);

  return hTemp; 
  }
   
  public static bool CryptionToolTrayIconIsExisted()
  {
  IntPtr pid = IntPtr.Zero;
  IntPtr lTextAdr = IntPtr.Zero; 

  IntPtr ipTray = GetTrayPointer();

  Win32API.GetWindowThreadProcessId(ipTray, ref pid);
  if (pid.Equals(0)) return false;

  IntPtr hProcess = Win32API.OpenProcess(Win32API.PROCESS_ALL_ACCESS | Win32API.PROCESS_VM_OPERATION | Win32API.PROCESS_VM_READ | Win32API.PROCESS_VM_WRITE, IntPtr.Zero, pid);
  IntPtr lAddress = Win32API.VirtualAllocEx(hProcess, 0, 4096, Win32API.MEM_COMMIT, Win32API.PAGE_READWRITE);

  // Get the tray icon number
  int lButton = Win32API.SendMessage(ipTray, Win32API.TB_BUTTONCOUNT, 0, 0);

  for (int i = 0; i < lButton; i++)
  {
  Win32API.SendMessage(ipTray, Win32API.TB_GETBUTTON, i, lAddress);
  Win32API.ReadProcessMemory(hProcess, (IntPtr)(lAddress.ToInt32() + 16), ref lTextAdr, 4, 0);

  if (!lTextAdr.Equals(-1))
  {
  byte[] buff = new byte[1024];

  Win32API.ReadProcessMemory(hProcess, lTextAdr, buff, 1024, 0);
  string title = System.Text.ASCIIEncoding.Unicode.GetString(buff);

  int nullindex = title.IndexOf("\0");
  if (nullindex > 0)
  {
  title = title.Substring(0, nullindex);
  }

  if ("application".Equals(title))
  {
  return true;
  }
  }
  }
  Win32API.VirtualFreeEx(hProcess, lAddress, 4096, Win32API.MEM_RELEASE);
  Win32API.CloseHandle(hProcess);

  return false;
  }

隐藏了还能取得吗？
可以设置快捷键，来启动隐藏的程序。

不懂，帮顶，等高手。
