如何在程序中关闭、重起和硬起动WCE、PPC、SP

关闭（suspend)

方法1：
//虚拟关机键
::keybd_event(VK_OFF, 0, 0, 0);
::keybd_event(VK_OFF, 0, KEYEVENTF_KEYUP, 0);

方法2：
//调用未公开函数PowerOffSystem()
extern "C" __declspec(dllimport) void PowerOffSystem();

重起(soft reset)
//Soft reset the device
#include 〈winioctl.h〉

#define IOCTL_HAL_REBOOT CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED, FILE_ANY_ACCESS)

extern "C" __declspec(dllimport) BOOL KernelIoControl(
DWORD dwIoControlCode,
LPVOID lpInBuf,
DWORD nInBufSize,
LPVOID lpOutBuf,
DWORD nOutBufSize,
LPDWORD lpBytesReturned);

BOOL ResetDevice()
{
return KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);
}

硬起动(hard reset)

//注意！！！使用此段代码会将您的Pocket PC的用户数据全部清空，
//请勿非法使用，用者后果自负.

#include 〈winioctl.h〉

#define IOCTL_HAL_REBOOT CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED, FILE_ANY_ACCESS)

extern "C" __declspec(dllimport)void SetCleanRebootFlag(void);

extern "C" __declspec(dllimport) BOOL KernelIoControl(
DWORD dwIoControlCode,
LPVOID lpInBuf,
DWORD nInBufSize,
LPVOID lpOutBuf,
DWORD nOutBufSize,
LPDWORD lpBytesReturned);

BOOL HardResetDevice()
{
SetCleanRebootFlag();
return KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);
}
