Question about importing v 5.5 chart data into v 6.2 chartfx

[User (Legacy)]

Hi there,

    I am currently evaluating ChartFX 6.2 ( we currently use clientserver

5.5 ) and was wonder about the compatibility of old chart formats with 6.2.

For saving files currently I use this method:

VARIANT v;

V_VT( &v ) = VT_STREAM;

V_UNKNOWN( &v ) = (IStream*)stream;

chart_fx->PutFileMask( (CfxFileMask)( chart_fx->FileMask |

FMASK_TEMPLATE ) );

hr = chart_fx->raw_Export( CHART_CFXOLEFILE, v, &result );

And read it back into chartfx via this method:

VARIANT v;

V_VT( &v ) = VT_STREAM;

V_UNKNOWN( &v ) = (IStream*)stream;

LARGE_INTEGER li;

li.QuadPart = (LONGLONG)0;

long result = 0;

stream->Seek( li, STREAM_SEEK_SET, NULL );

ok = SUCCEEDED( chart_fx->raw_Import( CHART_CFXOLEFILE, v, &result ) );

Will chartfx 6.2 be able to read this information?   Is the procedure any

different..either direction ( import/export ) for 6.2?  If there is a

problem...is there any way to convert from 5.5 to 6.2 in order for 6.2 to be

able to work with it?

Thank you for your time.
