        {
            InitializeComponent();
        }

        private void XtraForm1_Load(object sender, EventArgs e)
        {
            SkinHelper.InitSkinPopupMenu(SkinsLink);
            //Add skin to combobox
            foreach(SkinContainer cn in SkinManager.Default.Skins)
            {
                cboSkins.Properties.Items.Add(cn.SkinName);
            }
        }

        private void cboSkins_SelectedIndexChanged(object sender, EventArgs e)

        [STAThread]
        static void Main()
        {
            //Register skins
