I find the reason. It is because I execute pDiagram->GetAxisX()->GetRange()->GetViewMaxValue(); when I move the mouse. I now need to disable onmousemove when I zoom the range because I need to exeute PointToValue in mousemove event.How can i realize it,mutex does not work

I add sleep(50) after PointToValue. It works but there is a track shows where the mouse moved as it is not validated in time.

CXTPChartContent* pContent = GetContent();

CXTPChartSeriesCollection* pCollection = pContent->GetSeries();

CXTPChartDiagram2D* pDiagram = DYNAMIC_DOWNCAST(CXTPChartDiagram2D, pCollection->GetAt(0)->GetDiagram());

double internalValueX = ((CXTPChartDiagram2DAxisView*)pDiagram->GetAxisX()->GetAxisView())->PointToValue(pt.x);

I use these code in mousemove event. It crashes after I move my mouse several times. What may cause it?

thanks
