dtBLOB Access

TppField does not appear to have a AsBlob property to access a BLOB as a
TMemoryStream.

What is the best way to extract a binary BLOB [huge] into a TMemoryStream
from a DBpipeline inside of a "RecordPositionChange" event. I need to
extract this BLOB from the Master record, so I can parse it and make it
available in the Detail pipeline.

It seems ppFields has AsString, AsDouble, AsPicture, Variant, GUID, but no
AsMemory

    Found it. Seems only available thru the DBPipeline, and not the ppFIeld
    list.

    Correct, there is a DataPipeline.GetFieldAsStream method
