Hi Sir,

thanks for your help , now my database connection has been established. It becomes possible due to your guidance and help.

i have implemented the Try it out exercise of connecting SQL Server to database on page 406.
I have done all the thing according to your instruction. I have checked the security tab of my App_Data folder, it has modify permission checked.
I have log in to the administer account of my computer.
I mean to say that i have fulfill all the pre-requisite that you have told.

you first install SSMS and then reinstal the SQL server Express 2008.
and go to SQL Server Configuration manager and start the services there. If it does not start or give any error you just try to start it from control panel services.
