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

        private void Form1_Load(object sender, EventArgs e)
        {
            webBrowser1.Url = new Uri(string.Format("file:///{0}/Monaco/Monaco.html", Directory.GetCurrentDirectory()));
