What about
ref2 := ref1 as IStream; ??
If the variant has been passed from VBScript (or something else) it will be
either a IUnknown or IDispatch interface rather than a IStream. an
OLEVaraiant does not hold any arbitrary interface only.
Suggest you do a cast using tagVariant to check the actual types etc of the
variant.
