Not allowed to change the 'ConnectionString' property. The connection's current state is open

Hi *.*,

Yet Another error,Sharing your connections is the problem.

There is no need to share connections and creates problems like you are experiencing. .net's connection pooling handles the sharing of the real connections behind the scenes.

If u had any trouble just ask, Happy to help u :) 

Stay Tune... 

Have a nice day... 'N happy Coding :)
