如何在程式中關閉、重起和硬起動WCE、PPC、SP

 

關閉（suspend)

方法1：
//虛擬關機鍵
::keybd_event(VK_OFF, 0, 0, 0);
::keybd_event(VK_OFF, 0, KEYEVENTF_KEYUP, 0);

方法2：
//調用未公開函數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);
}

 

硬起動(hard reset)

//注意！！！使用此段代碼會將您的Pocket PC的使用者資料全部清空，
//請勿非法使用，用者後果自負.

#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);
}
