Well, a .Refresh definitely is not efficient :-)
I was looking for a way to refresh a *single* dataset.
The table is very big and the sql can be customized, so a refresh may
take up to a few seconds, maybe even minutes.
I've dug into the BufferFieldByName function, just to notice that there is
IMHO no way to actively manipulate the buffer (since I alread *have* the
correct data in a Cursor, this would be the best way).
