Export and OLE Stream

Is it possible to export to an OLE Stream object in VB for ChartFX

Client-Server? If so, how is it done? The API Guide claims it can be done

but there is no sample or further explanation.

What I am trying to do is get the chart settings (visual attributes) into an

XML document. My application already stores content in an XML document and

I want to be able to add the chart settings to this document without having

to write them out individually.

What version of Chart FX are you using ? I'm guessing is Chart FX 5.x (COM).

The export method can export to a BINARY stream, not to an XML.

If you have a pointer to an IStream object you can do:

chart.Export CHART_CFXOLEFILE, <stream pointer>

This however will write a BYNARY stream that CAN NOT be embedded into an XML

(unless you do a Base64 encoding).
