Question

I am trying to build a sql query which will run a stored procedure. I then need the result of this query to appear in a listbox from which a user can select the desired result.

Please could someone show me how to construct the SQL query from scratch first of all, then show me how to get this result into a listbox?

Thanks in advance!

{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            FillData();
        }

        void FillData()
        {
            var connString = ConfigurationManager
                .ConnectionStrings[name].ConnectionString;

            using (SqlConnection c = new SqlConnection(connString))
            {
                c.Open();

                // use a SqlAdapter to execute the query
                using (SqlDataAdapter a = new SqlDataAdapter("SELECT * FROM EmployeeIDs", c))
                {            
                    // fill a data table
                    var t = new DataTable();
                    a.Fill(t);

                    // Bind the table to the list box
                    listBox1.DisplayMember = "NameOfColumnToBeDisplayed";
                    listBox1.ValueMember = "NameOfColumnToUseValueFrom";
                    listBox1.DataSource = t;
                }
            }
        }
    }
