Hi at all,

I created a map file with some ovf connections, 2 vector datasets end 
~30 raster image (topographical map 1:10000).
MapLab is really good to use them, and it is also fast. but if I try to 
query some "ovf" features it spends a lot of time because there are the 
30 raster image. How can i say to maplab to query only features I want?
I have a second question: i would like to learn more and custumize my 
application, what is the better way? I know vb, avenue, I followed 
maplab , php , mysql tutorials. but I have great troubles to understand 
custumize mapserver application (query, commands ecc) do you have some 
suggetions? thanks a lot!!!!
