void CTestDevInfoDlg::OnBtnGetRibbonInfo()
{

DWORD dwRet = 0;
DWORD dataArray[32] = {0};
DWORD dwLen = 0;
TCHAR szType[32] = {0};
TCHAR szCount[32] = {0};

dwRet = HITI_GetDeviceInfoW(0, 4, (unsigned char *)dataArray, &dwLen);

if ( dwRet == 0 )
{
_stprintf(szType, _T("%d"), dataArray[0]);
m_EditRibbonType.SetWindowText(szType);
_stprintf(szCount, _T("%d"), dataArray[1]);
m_EditRibbonCount.SetWindowText(szCount);
}
else
{
_stprintf(szType, _T("Error code = %d"), dwRet);
MessageBox(szType, _T("OnBtnGetRibbonInfo"), MB_OK);
}
}
