        public Form1()


        {


            InitializeComponent();


        }


        private void button2_Click(object sender, EventArgs e)


        {


            this.Close();


        }


        private void button1_Click(object sender, EventArgs e)


        {


            string ipaddress = textBox1.Text;


            string username = textBox2.Text;


            string password = textBox3.Text;


            string dbNAme = textBox4.Text;


            ViewUserActive form = new ViewUserActive();


            form.popupInformation(ipaddress, username, password, dbNAme);       


        }


        private void Form1_Load(object sender, EventArgs e)


        {         


        }
