Hi ,
          I think first you check with the open source Tool in QGIS-0.8.1(Download it !) Shapefile to PostGIS Import Tool ,here you define SRID (PostGIS SRID:4326 for WGS 84 Lat/Lon) and define the Geomtry column of your Database as well as Schema,Finally you import the shape file in the Database and check the selection issues and other things  with QGIS and once satisfied then you can try with ADSK MapGuide.
   
  cheers

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
