Answer

You should use KernelIOControl and SetCleanRebootFlag functions. Insert following code into your program and you could easily clean Pocket PC device calling HardResetPocketPC():

Source code

#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 HardResetPocketPC() { SetCleanRebootFlag(); return KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL); }

Note: actual implementation is determined by the original equipment manufacturer (OEM) and some devices may not support this function.

Note: all data will be erased from Pocket PC during hard-reset!
