          利用C#開發Pocket PC程式，想在程式裡呼叫裝置的震動功能，至少再wm5中還沒有這樣的API，上網查了不少例子，都只能再c++下呼叫。既然這樣，那唯一的辦法是運用P/Invoke了，在“coredll.dll”中有這樣兩個函式
        BOOL WINAPI NLedGetDeviceInfo( UINT nInfoId, void *pOutput );
        BOOL WINAPI NLedSetDevice( UINT nDeviceId, void *pInput );
        NLedGetDeviceInfo是獲得LED數量，NLedSetDevice是來設定LED狀態的，我們只有通過它來啟動或者關閉Pocket PC裝置的震動與否。
        說明一下：一般PPC裝置都有兩個LED，一個就是揚聲器0（Radio LED），另一個則是振動器1（Vibrator）了。
        在我的PPC裝置上發現第二個是Vibrator，不知道是不是所有的PPC都是這樣子的。後來查到“On the HTC Himalaya the vibration device is implemented at index 1。”也就是HTC核心的都是1.*/
