Load a TOleContainer from a stream which contains a file image, without using CreateObjectFromFile

Hi,
I have a database which contains blobs loaded from file of various MS doc types such as Word and Excel.  I'm trying to load these into a TOleContainer in much the same way that CreateObjectFromFile() works, however, without having to write the contents out to disk, etc.  I've tried a number of combinations to no avail.  Below is a code snippet which may at least help in conveying what I am trying to accomplish.

Any help would be greatly appreciated!

...
      try
        Stream:=TMemoryStream.Create; {Creation memory stream and saving content from database}
        TBlobField(FDataLink.Field).SaveToStream(Stream);
        Stream.Seek(0,soFromBeginning);
        S := GetAssociatedClassname(ExtractFileExt(aOriginalFileName));  // Returns, for example, "Excel.Sheet.8" or "Word.Document.8"
        CreateObject(S, False);
        // LoadFromStream(Stream);  // doesn't work!!!!  ...Invalid Stream format
        if Assigned(Stream) then
          begin
            Stream.Free;
            Stream:=nil;
          end;
      except
        on E:exception do begin
          if Assigned(Stream) then Stream.Free;
          Raise;
        end;
      end;
