Hi Steve,
dbase tables don't have indexed fields and when I query the database,
I extract some records in a new recordset. If, as record number, you
consider the absolute position in the original table I cannot have that
number.
Maybe it's possible to scroll all the database with a Find command but
probably it would be very slow for large tables....
I 'm new in mapserver, can I find somewhere sample code that opens =
shapefile
and reads extents for a feature?

Thank you

Mario

MapServer &gt; Hi Mario, &gt; &gt; If you can read the =
dbf and=20
have the record number, then you need to &gt; open the shapefile and =
read the=20
extents for that record number, then &gt; you can call=20
$map-&gt;setextent(xmin, ymin, xmax,ymax) and you should be &gt; all=20
