you should call (cmd.Dispose();).

finally
{
    if (rdr != null)
    {
        rdr.Close();
    }
    if (con != null)
    {
        con.Close();
        con.Dispose();

                    cmd.Dispose

         Console.WriteLine("Added calculator to automatic startup. Press any key to continue...");

//check if it already contains a dot '.' character by using the text property
//if it does then allow only number and refuse everything else using
e.Handled=true;
e.SuppressKeyPress=true;
//also check the number of chars after the '.' sign

//else allow dot and numbers. 

e.KeyCode == Keys.OemPeriod
