Serialize COM variant to BLOB or IStream

Question

Is there a standard way to serialize and deserialize a COM VARIANT, e.g. to/from a stream?

Haven't found any in MSDN, an I'm a little surprised now.

Answer 1

You can do this using the the VARIANT_UserMarshal function.

General information on this function (and similar ones for other OLE Automation types) is available here: Marshaling OLE Data Types and here: The type_UserMarshal Function
