using System;
using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int ok = 0;
            if (String.IsNullOrEmpty(textHeight.Text)) {
                MessageBox.Show("Height must not be Empty");
                ok = 1;
            }
            if (String.IsNullOrEmpty(textName.Text))
            {
                MessageBox.Show("Name must not be Empty");
                ok = 1;
            }
            if (ok == 0) {
                try {
                    int result = int.Parse(textHeight.Text);
                    }
                catch {
                    MessageBox.Show ("Height Not a valid integer");

                                double BMI = Weight / Math.Pow(Height / 100.0, 2);
                MessageBox.Show ("Name: "
