Thanks for the response.  The example you sent is what I tried to follow when I originally worked on this.  It works great for the first 255 bytes, but after that it returns 0's.  Is there any way to get all of the data in a large object returned to a recordset (not just the first 255 bytes)?  Thanks again.
