Thankyou for any help

Check out the link below. Notice that you must provide the actual path to the database. Contact your web hosting provider and find out the path. It's usually C or D drive then bunch of directories and subdirectories. For example,
d:\web\root\client\abc.com\ this would be your account folder and it set such a way that you cant go out of this directory. So this is the path you will have to provide in order for db to connect.

@praveenb000
No you aren't.

@praveenb000
See the <connectionStrings /> tag?
It's an empty tag!

Please take a look at this article on how to read connection strings from the Web.config file for more information on how you should storing and retrieving your connection string.

Thank you very much Lol (dorandoran,Frinavale)

[dorandoran]

praveen , please post your solution so other can follow if they are having similar issue(s). thanks.
oh, glad you found the workaround.

[praveenb000]

ya, this is what i did to solve

 <add key="con" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=http://vijayawadanalanda.org/dbnalanda/nalandavja.mdb;Persist Security Info=True"/>

i placed my access database file in App_Data folder

and changed the data source as

<add key="con" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|nalandavja.mdb;Persist Security Info=True"/>

Anyway, Thanks for your team members for supporting us at any time.
