    {
        public DecimalTrackBar()
        {
            InitializeComponent();
        }
        private void InitializeComponent()
        {
            components = new System.ComponentModel.Container();
        }

                {  
                    components.Dispose();  
                }  
            }  
            base.Dispose( disposing );  
        }  
        private void RecalcValue()  
        {  
            Value = (decimal)(base.Value * factor);  
        }  
        protected override void OnValueChanged(EventArgs e)  
        {  
            base.OnValueChanged(e);  
            RecalcValue();  
        }  
        protected override void OnScroll(EventArgs e)  
        {  
            base.OnScroll(e);  
            RecalcValue();  
        }
