I need to use KernelIoControl to read this damned serial number. I tried all
tricks and fall into conclusion, that with eVC++ I cant use this fuction.
What do I need? Platform Builder??

Define the label WINCEOEM at the project level. KernelIoControl is in the
headers, just ifdef'd out by default.

BTW, the implementation of a standard serial number on any CE devices to
date has been optional for the OEMs. You may not get anything useful back.

No, it doesnt work. When I define it, I get message like "pkfucs.h
missing" - i dont have this file on disc!. When i mimic presence of this
file and apriopriate definitions, the linker canot find KernelIoControl.. -
its not in the library!

When I defined the function KernelIoControl in the way I show you below the
function was working.
I can reboot the system but I steal can't access device serial number on the
Compaq AERO 1550.

Does exist on Compaq any other method to access the serial number?

#include <WinBase.h>
#include <winioctl.h>

extern "C" {

BOOL KernelIoControl(DWORD, LPVOID, DWORD, LPVOID, DWORD, LPDWORD );

#define IOCTL_HAL_GET_DEVICE_INFO CTL_CODE(FILE_DEVICE_HAL,1,

#define IOCTL_HAL_REBOOT CTL_CODE(FILE_DEVICE_HAL, 15,

#define IOCTL_HAL_ENABLE_SCHEDULER_LOGGING CTL_CODE(FILE_DEVICE_HAL, 16,

#define IOCTL_SET_KERNEL_DEV_PORT CTL_CODE(FILE_DEVICE_HAL, 17,

#define IOCTL_HAL_GET_DEVICEID CTL_CODE(FILE_DEVICE_HAL, 21,
METHOD_BUFFERED, FILE_ANY_ACCESS)

typedef struct _DEVICE_ID {
DWORD dwSize;
DWORD dwPresetIDOffset;
DWORD dwPresetIDBytes;
DWORD dwPlatformIDOffset;
DWORD dwPlatformIDBytes;
} DEVICE_ID, *PDEVICE_ID;
}

Use it this way:
{
// This works!
// KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);

DEVICE_ID DevInfo;
DWORD RetBytes;
DevInfo.dwSize = sizeof(DEVICE_ID );
BOOL bError;

bError = KernelIoControl ( IOCTL_HAL_GET_DEVICEID,
NULL, 0,
&DevInfo, sizeof(DEVICE_ID), &RetBytes);
}

Good luck!

I got the same problem. does anyone have already a solution for getting the
device_id?
i tried to read it from a jornada 720.

with regards
