[Mapserver-users] queryByShape explanation please

[Gijs Epping]

Hello,

I have some problems with the polygon shape query on a multiple point
shape file, Could some body explane it to me how i can get the data from
the points that lay in the polygon zone. The areacode layer is just some
point data. At the moment it gives this error:
Warning: [MapServer Error]: msQueryByShape(): No matching record(s)
found.

But in the zone are I think 100 point present.

This is the code that generates the polygon circle thanks to the some
Mapserver users.

Thanks in advance.
