}
private void Login_btn_Click(object sender, EventArgs e) //Log In Button
{
string user = id_txt.Text;
string pass = Pwd_txt.Text;
cmd = new MySqlCommand();
con.Open();
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM demo_login where id='" + id_txt.Text + "' AND password='" + Pwd_txt.Text + "'";
dr = cmd.ExecuteReader();

if (dr.Read())

  • Never glue bits of string together to make a SQL query - use SQL Parameters always. Never ever store passwords as plain text - salt and hash them.
