Hi how can I pass the connection string from my Main Form to Another form without retyping again those strings. Let say I have separate form for Adding data to database.

Here is my connection codes.

Code:
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }

        SqlConnection con;
        DataSet ds1;
        SqlDataAdapter da;


        private void frmMain_Load(object sender, EventArgs e)
        {

        }

        private void loadRecords_Click(object sender, EventArgs e)
        {
            con = new SqlConnection();
            con.ConnectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\MyMDB Records\\myMDB.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
            ds1 = new DataSet();

            con.Open();
            string sql = "SELECT * FROM tblClients";
            da = new SqlDataAdapter(sql, con);


            da.Fill(ds1, "Clients");
            loadLitview();
            con.Close();
            con.Dispose();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            frmAdd FormAdd = new frmAdd();
            FormAdd.Show();
        }
Ho can I make that call from my other form which is Adding records to db?
