The GetDecodedContentStream() method returns an object and VFP doesn't have a built-in way to persist an object.
Try

		loStream = loAttachment.GetDecodedContentStream()
		lwStream = loStream.Read()
		INSERT INTO Attachments (iTimeId, wAttachmnt) VALUES (lnTimeId, lwStream)

BTW, why not store just attachment itself?
