I followed the link http://mobileworld.appamundi.com/blogs/andywigley/archive/2008/12/08/building-a-sync-services-for-ado-net-solution-for-mobile-devices.aspx
and was able to sync DB.
Problem is that it is only for static connection string and Server IP where SQL server DB is located which i provided through designer wizard. now i want to change the connection string and Server IP as provided in some file.So that user can change the Server DB location and synchronize.I don't know how to proceed.Please Help
