Hi Kenneth,

Thankyou for your replay once again. If OGR provider have no problem in
selection then i can use OGR Provider in place of PostGIS provider. I am
using MGOS 1.2.0 RC2 and Autodesk MapGuide studio 2007. So, from where i'll
get OGR Provider that work fine with  MGOS 1.2.0 RC2. Thankyou in Advance.

Regards,
Dhirendra Kumar
