I can't get hwnd of chrome in my project running as service

I want to get hwnd of chrome.So I made it and I confirmed it was successful on debug mode. But I can't get hwnd with my program running as service. What is wrong?

TCHAR szClassName[MAX_PATH] = _T("Chrome_WidgetWin_1");
TCHAR szDetailedName[MAX_PATH] = _T("xxxx");
TCHAR szTitle[MAX_PATH], szClassNameWnd[MAX_PATH];

hWndTemp = ::GetForegroundWindow();
hWndTemp = ::GetWindow(hWndTemp, GW_HWNDFIRST);

while (::GetWindow(hWndTemp, GW_HWNDNEXT) != NULL)
{
    hWndTemp = ::GetWindow(hWndTemp, GW_HWNDNEXT);
    ::GetClassName(hWndTemp, szClassNameWnd, MAX_PATH);
    ::GetWindowText(hWndTemp, szTitle, MAX_PATH);

    if (szClassName != NULL && _tcscmp(szClassNameWnd, szClassName) == 0)
    {
        if (szDetailedName == NULL)
        {
            EnumChildWindows(hWndTemp, (WNDENUMPROC)EnumWindowsProc, LPARAM("Chrome_RenderWidgetHostHWND"));
            return TRUE;
        }
        .....
    }
}
