<P>Hi all,</P>
<P>Can anyone tell me if there is a way to catch the error that getShape throws
if you request a shape that is out of range? </P>
<P>Reason is I'm trying to iterate through a layer. At this stage, I need to use
an object count to make the loop stop. Getting an object count either requires
me to use the shpfileobj->numshapes variable (which obviously only works on
shapefiles), or doing a query (which would only work on layers with templates,
which would need a reprojected rectangle, uses overhead, etc….).</P>
<P>Would it be possible to make getShape return MS_FAILURE if the object is out
of range, or throw a warning that can be caught using '@' error suppression?
That way one could iterate through a whole layer without needing a layer
count.</P>
<P>Regards,</P>
<P>Jacob</P>
