Hi Rahul,

Thankyou for your replay, when i direct import .SHP file in Mapguide then it
is working fine. but when i import shp file in PostGIS database using
shp2pgsql then i get selection problem on Layer. I import .SHP file in
PostGIS database using SHP2pgsql syntex :- (1). shp2pgsql -c block.shp
public.block > block.sql
(2). psql -d postgis -U postgres -f block.sql
Rahul help me where i m wrong ? We use Lat,Long projection system and Datum
WGS 84. Any problem in importing SHP File ? Rahul i'll have to Set any
Enviorment ( PGSQL_OGR_FID  )variable for OGR Provider to comunicate with
PostGIS Database Layer ? if yes then how. Please help me. Thankyou in
Advance.

Regards,

Dhirendra Kumar
