Problem to save in stream

[User (Legacy)]

ChartFX write nothing in my stream.

There is no error in return export function, but IStream::Stat function

retrieve no size.

If  I try to export with CHART_CFXOLEFILE, I have an error: 0x800004005.

What may be the problem?

Thanking you in advance,

sample code:

-------------

  IStreamPtr pStream;

  HRESULT    hResult = CreateStreamOnHGlobal (NULL, TRUE, &pStream);

  VARIANT    varValue;

  if (SUCCEEDED(hResult))

  {

      V_VT(&varValue) = VT_UNKNOWN;//VT_STREAM;

      V_UNKNOWN(&varValue) = m_pStream;

      hResult = m_pChartFX->Export(CHART_CFXFILE, varValue);

      STATSTG stg;

      memset (&stg, 0x00, sizeof(STATSTG));

      hResult = m_pStream->Stat (&stg, 0);

   }

You need to use the following code:

    V_VT(&varValue) = VT_STREAM;

    V_UNKNOWN(&varValue) = m_pStream;

    m_pChartFX->raw_Export(CHART_CFXFILE, &varValue,&hResult);

The _variant_t wrapper can't handle VT_STREAM
