小弟我用VS2008实现WM的手机震动，从网上找的源码,可是找不到nled.h文件

我用VS2008实现WM的手机震动，从网上找的源码,可是找不到nled.h文件
源码如下
#include "定时闹钟.h"
#include "定时闹钟Dlg.h"
#include <windows.h>
#include <commctrl.h>
//下面include 本身是#include <nled.h> 可是找不到文件，我用搜索找到nled.h后，更改了包含目录如下
#include "D:\Program Files\Microsoft Visual Studio 9.0\SmartDevices\SDK\PocketPC2003\Include\nled.h"
//但是提示 error C3861: “NLedSetDevice”: 找不到标识符
//我在“D:\Program Files\Microsoft Visual Studio 9.0”目录下寻找包含NLedSetDevice关键字的文件，结果
//一个没找到:(郁闷

void StartVirbate()
{
  NLED_SETTINGS_INFO settings ; 

  memset(&settings,0,sizeof(NLED_SETTINGS_INFO));
  settings.LedNum= 1; 
  settings.OffOnBlink= 1;
  NLedSetDevice(NLED_SETTINGS_INFO_ID, &settings);
}

void StopVirbate()
{
  NLED_SETTINGS_INFO settings; 

  memset(&settings,0,sizeof(NLED_SETTINGS_INFO));
  settings.LedNum= 1; 
  settings.OffOnBlink= 0;
  NLedSetDevice(NLED_SETTINGS_INFO_ID, &settings);
}


void C定时闹钟Dlg::OnBnClickedButtonZhendong()
{
// TODO: 在此添加控件通知处理程序代码
  StartVirbate();
  StopVirbate();
}

------解决方案--------------------
Vibrate实现振动，VibrateStop停止振动，VibrateGetDeviceCaps返回设备对振动的支持情况。
HRESULT Vibrate(DWORD cvn, const VIBRATENOTE * rgvn, BOOL fRepeat, DWORD dwTimeout);
HRESULT VibrateStop (void);
int VibrateGetDeviceCaps (VIBRATEDEVICECAPS vdc);
