[DotNetDevelopment] sql server connectivity

[stanlei]

i've been trying this for days and i just dont know what the problem
is ...

im using:

private string conns = "Data Source = 'MOI-PC/SQLEXPRESS;Initial
Catalog = Project; User ID = sa; Password = madurai'; Connect Timeout
=  60;";

SqlConnection conn = new SqlConnection(conns);
            conn.ConnectionString = conns;

            try
            {
                conn.Open();
            }
            catch (Exception ex)
            {

                MessageBox.Show("ERROR \n"+ex.Message);
            }

All i get is ..

A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I use Windows Vista Ultimate SP2, SQL server 2005 SP3 and Visual
Studio 2005
sql server is configured to accept remote connections .... both tcp/ip
n named pipes
my sql browser is running ....

any help would be greatly appreciated!!
