Get Device ID | Unitech PA500 guide

8. Useful function call - without include SysIOAPI.DLL

8.1.Warm-boot, Cold-boot and power off

#include <pkfuncs.h>

#include "oemioctl.h"

//Warn boot

KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);

// Cold boot

KernelIoControl(IOCTL_COLD_BOOT, NULL, 0, NULL, 0, NULL);

//Power off

{

DWORD dwExtraInfo=0; BYTE bScan=0;

keybd_event( VK_OFF, bScan, KEYEVENTF_SILENT, dwExtraInfo ); keybd_event( VK_OFF, bScan, KEYEVENTF_KEYUP, dwExtraInfo );

}

8.2.Get Device ID

In PA500, an unique ID had been burnt into terminal, user can check it by pressing “Func”+”9”.

The sample code for read device ID as follow,

////////////////////////////////////////////////////////////////

HWND hDeviceId = GetDlgItem(hWnd, IDC_DEVICEID);

PDEVICE_ID pDeviceID = NULL;

TCHAR outBuf[512], szProductID[100], stringBuffer[100]; BYTE szBuff[255];

DWORD bytesReturned; char platformID[64];

pDeviceID = (PDEVICE_ID)outBuf; pDeviceID->dwSize = sizeof(outBuf);

if (KernelIoControl(IOCTL_HAL_GET_DEVICEID, NULL, 0, outBuf, sizeof(outBuf), &bytesReturned))

{

// Platform ID

memcpy((PBYTE)platformID, (PBYTE)pDeviceID + pDeviceID->dwPlatformIDOffset, pDeviceID->dwPlatformIDBytes);

// Device ID for WinCE version

memcpy((PBYTE)stringBuffer, (PBYTE)pDeviceID + pDeviceID->dwPresetIDOffset, pDeviceID->dwPresetIDBytes); swprintf(szProductID, _T("%s"), stringBuffer);

// Device ID for Mobile version

memcpy((PBYTE) szBuff, (PBYTE)pDeviceID + pDeviceID->dwPresetIDOffset, pDeviceID->dwPresetIDBytes); swprintf(szProductID, TEXT("%X%X%X%X%X%X%X%X"),

szBuff [0], szBuff [1], szBuff [2], szBuff [3], szBuff [4], szBuff [5], szBuff [6], szBuff [7]);

}

/////////////////////////////////////////////////////////

The code will have platformID holds Platform ID, and deviceID holds Device ID.
