// Query the service provider for IWPCBlockedUrls
hr = _psp->QueryService(IID_IWPCBlockedUrls, IID_PPV_ARGS(&pBlockedUrls));
if (SUCCEEDED(hr))
{
    DWORD  dwCount;
    if (SUCCEEDED(pBlockedUrls->GetCount(&dwCount)) && (dwCount>0))
    {
        BSTR * pargUrls = (BSTR*) LocalAlloc(LPTR, dwCount*sizeof(BSTR*));

        if (NULL != pargUrls)
        {
            BSTR * pbstrUrl = pargUrls;
            
            // Retrieve URLs into pointer array
            for (DWORD dwIdx=0; dwIdx < dwCount; dwIdx++)
            {
                hr = pBlockedUrls->GetUrl(dwIdx, pbstrUrl);
                if (FAILED(hr)) break;
                pbstrUrl++;
            }
            
            // *** Use the list of URLs here
            
            // Free array and elements
            pbstrUrl = pargUrls;
            for (DWORD dwIdx=0; dwIdx < dwCount; dwIdx++)
            {
                if (!*pbstrUrl) break;
                SysFreeString(*pbstrUrl);
                pbstrUrl++;
            }
