Hi Murua，

Hi Murua,

string dataSource = txtDataSoure.Text;
            string database = txtDatabase.Text;
            string user = txtUser.Text;
            string password = txtPassword.Text;

         public  static string con = "Data Source="+dataSource+";Initial Catalog="+database+";User Id="+user+";Password="+password;
           System.Data.SqlClient.SqlConnection sqlCon = new System.Data.SqlClient.SqlConnection(con);
