        const int AW_HOR_NEGATIVE = 0X2;

        const int AW_BLEND = 0X80000;

        [DllImport("user32")]

        static extern bool AnimateWindow(IntPtr hwnd, int time, int flags);

        #endregion

        #region Onload

        protected override void OnLoad(EventArgs e)

        {

            AnimateWindow(this.Handle, 500, AW_SLIDE | AW_HOR_POSITIVE);

        }
