| MapPointUtilities Any sugestions are welcome! my code looks like this: Code: CComPtr<MapPoint::_MapPointUtilities> pUtils(NULL);

if(SUCCEEDED(hr))
{
LPDISPATCH pPictureDisp(NULL);
hr = pUtils->GetPictureFromObject(m_pMappointMap, 640, 480, &pPictureDisp);
if(SUCCEEDED(hr))
{
long cbSize(0);
IPicture* pPicture(NULL);
hr = pPictureDisp->QueryInterface(__uuidof(IPicture), (void**)&pPicture);
if(SUCCEEDED(hr))
{
SHORT sType(0);
hr = pPicture->get_Type(&sType);
hr = pPicture->SaveAsFile(pStream, TRUE, &cbSize);
}
pPicture->Release();
}
}
pUtils.Release();

Hi there, The problem with GetPictureFromObject is that the Height and Withd of this function is in HiMetrics. Regarding msdn.com, visual basic references for MapPoint the minimal value must be 1100 for both ot them. Quote:
