Hi all,
How can I get attachment binary data without saving it on a file?
I try with the following code but HrGetOneProp give me E_OUTOFMEMORY if the
attachment is 670 KB.

HRESULT GetAttachmentBinaryProp(Outlook::Attachment *atch, std::vector<byte>
&binProp)
{
   if (!atch)
       return E_FAIL;
   HRESULT hr;
   CComQIPtr<Outlook::Attachment> attachment(atch);
   CComPtr<IUnknown> mapiObj;
   hr = attachment->get_MAPIOBJECT(&mapiObj);
   if (FAILED(hr))
       return hr;
   LPSPropValue lpProps = NULL;
   hr = HrGetOneProp((LPMAPIPROP)(IUnknown*)mapiObj, PR_ATTACH_DATA_BIN,
&lpProps);
   if( lpProps && lpProps->ulPropTag==ulPropTag && lpProps->Value.bin.cb )
   {
       memcpy(&binProp[0], lpProps->Value.bin.lpb, binProp.size());
       return S_OK;
   } else
   {
       return E_FAIL;
   }
}

Everything works well if the attachment is little (e.g. 4 KB).
Could anyone help me?
Thanks
