使Pocket PC震起来

       这是我在网上查到的一份源代码，虽然很简单，不过很有意思。它的功能是使Pocket PC所在的机子震动，非常适合用来做游戏特效。下面贴出来分享一下：

#include

#include

// from the platform builder

extern "C" {
BOOL WINAPI NLedGetDeviceInfo( UINT nInfoId, void *pOutput ); 
BOOL WINAPI NLedSetDevice( UINT nDeviceId, void *pInput );
};

void LedOn(int id)
{
NLED_SETTINGS_INFO settings;
settings.LedNum= id;
settings.OffOnBlink= 1;
NLedSetDevice(NLED_SETTINGS_INFO_ID, &settings);
}
void LedOff(int id)
{
NLED_SETTINGS_INFO settings;
settings.LedNum= id;
settings.OffOnBlink= 0;
NLedSetDevice(NLED_SETTINGS_INFO_ID, &settings);
}
int WINAPI WinMain( HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
for (int i=0 ; i<10 ; i++)
{
LedOn(1);
Sleep(400);
LedOff(1);
Sleep(200);
}

return 0;
}
