    Declare those DataReader in the block public partial class Form1 : Form Example:

    namespace GoodFood_1_
    {
        public partial class Autentificare_client : Form
       {
            SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Users\edi_b\Documents\visual studio 2013\Projects\GoodFood(1)\GoodFood(1)\GOOD_FOOD.mdf;
            Integrated Security=True;MultipleActiveResultSets=True");
            SqlConnection con2 = new SqlConnection(@"Data Source=(LocalDB)\v11.0;AttachDbFilename=c:\users\edi_b\documents\visual studio 2013\Projects\GoodFood(1)\GoodFood(1)\GOOD_FOOD.mdf;
            Integrated Security=True;MultipleActiveResultSets=True");
    
            SqlDataReader dr;
            SqlDataReader cc;
    
            public Autentificare_client()
            {
                InitializeComponent();
            }
