("server=sql2.bitsonthewire.com;uid=joeuser;pwd=joeuser;database=northwind");
SQLDataSetCommand CustomersDSCommand = new SQLDataSetCommand("select * from customers", myConnection);
dsCustomer = new DataSet();
CustomersDSCommand.FillDataSet(dsCustomer,"Customers");
foreach (DataRow Customer in dsCustomer.Tables["Customers"].Rows)
