well, you can't just add a shape to the .shp file and a dbase record to 
the .dbf file and have them correlate. remember, they are linked 
together by the interim .shx file. I haven't done this, but I am 
assuming the shape adding method automatically creates a linked, empty 
dbf record.


in any case, I think Guillaume is wanting to draw "annotations"... just 
for temporary display. In which case, he would want to add shapes, not 
in the ESRI shapes sense, but shapes in the geometric (or non-geom) 
shapes sense.
