Platform exceptions

[ren37]

Hello

A user report these errors. Trace attached.
As I can see something bad happened with UI events handling inside the platform.

I use this code for attaching input events handlers to indicators

// indicator class
        protected MouseEventHandler handlerOnMouseMove;
        protected MouseButtonEventHandler handlerOnMouseDown;
        protected MouseButtonEventHandler handlerOnMouseUp;
        protected MouseButtonEventHandler handlerOnMouseDoubleClick;
        protected KeyEventHandler handlerOnKeyDown;
        protected KeyEventHandler handlerOnKeyUp;

        public void AttachEventHandlers()
        {
            if (GetChartPanel() != null)
            {
                handlerOnMouseMove = new MouseEventHandler(IndicatorMVC.OnMouseMove);
                GetChartPanel().MouseMove += handlerOnMouseMove;

                handlerOnMouseDown = new MouseButtonEventHandler(IndicatorMVC.OnMouseDown);
                GetChartPanel().MouseDown += handlerOnMouseDown;

                handlerOnMouseUp = new MouseButtonEventHandler(IndicatorMVC.OnMouseUp);
                GetChartPanel().MouseUp += handlerOnMouseUp;

                handlerOnMouseDoubleClick = new MouseButtonEventHandler(IndicatorMVC.OnMouseDoubleClick);
                GetChartPanel().MouseDoubleClick += handlerOnMouseDoubleClick;

                handlerOnKeyDown = new KeyEventHandler(IndicatorMVC.OnKeyDown);
                GetChartPanel().KeyDown += handlerOnKeyDown;

                handlerOnKeyUp = new KeyEventHandler(IndicatorMVC.OnKeyUp);
                GetChartPanel().KeyUp += handlerOnKeyUp;
            }
        }

        public void DetachEventHandlers()
        {
            if (GetChartPanel() != null)
            {
                if (handlerOnMouseMove != null) { GetChartPanel().MouseMove -= handlerOnMouseMove; handlerOnMouseMove = null; }
                if (handlerOnMouseDown != null) { GetChartPanel().MouseDown -= handlerOnMouseDown; handlerOnMouseDown = null; }
                if (handlerOnMouseUp != null) { GetChartPanel().MouseUp -= handlerOnMouseUp; handlerOnMouseUp = null; }
                if (handlerOnMouseDoubleClick != null) { GetChartPanel().MouseDoubleClick -= handlerOnMouseDoubleClick; handlerOnMouseDoubleClick = null; }
                if (handlerOnKeyDown != null) { GetChartPanel().KeyDown -= handlerOnKeyDown; handlerOnKeyDown = null; }
                if (handlerOnKeyUp != null) { GetChartPanel().KeyUp -= handlerOnKeyUp; handlerOnKeyUp = null; }
            }
        }

        public ChartPanel GetChartPanel()
        {
            return (MasterIndicator == null) ? ChartPanel : MasterIndicator.ChartPanel;
        }

        protected override void OnStateChange()
        {
            ...

            else if (State == State.Historical)
            {
                AttachEventHandlers();
                ...
            }
            else if (State == State.Terminated)
            {
                DetachEventHandlers(); 
                ...
            } 

Any advice?

Hello ren37,

The MachineID can be used to license scripts for unauthorized machines. This is included with the log and trace files.

My indicators use another machine id for license checking.
