Thanks for reply,
but it has the same error as it was giving earlier,

and the error is

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

 on line adp.fill(ds);

Sry
Even i'm also getting the same error in one of my application
if u get the solution then plz forward it to me also
thank u in advance

Check your connectionstring. It may be incorrect.
Try this connectionstring:
SqlConnection con = new SqlConnection("Server=localhost;Database=vinod;uid =sa;pwd=;");
                   Or,
SqlConnection con = new SqlConnection("Server=FullDatabaseName;Database=vi nod;uid=sa;pwd=papa;");

Thanks Gaurav,

but i solved this problem using
SqlConnection con = new SqlConnection("server=localhost;database=vinod;Integrated Security=True");
 and set sql server on windows authentication mode.
