How to clear ChartFX object?

[User (Legacy)]

Hello,

I have a problem on memory issue.

I am using a timer, so the chart on ActiveX Control is being refreshed in

every second.

The chart is not dynamically created. That is, the chart is statically

docked on ActiveX Control.

So, I clear the objects in order to release memory.

However, when some hours elapse, an error occur on a method like ClearData.

And, when I try to debug(simply, Ctrl+C), "memory lack" message pop up.

But, at that time, VB6.exe use system memory under 20MB and virtual memory

under 20MB.

My system memory is totally 1GB.

My code like this... (VB)

Thanks in adv. 

Private Sub Timer1_Timer()

    call RefreshChart(m_chartSrc)

End Sub

Private Sub RefreshChart(ByRef chartSrc As clsChartDefinedMyClassModule)

    With cfxTheStaticChartOnActiveXControl

        'Clear

        .ClearData CD_ALLDATA Or CD_OTHER

        .ClearLegend CHART_LEGEND Or CHART_SERLEG Or CHART_KEYLEG Or

CHART_FIXLEG Or CHART_YLEG

        'General Setting

        .BorderStyle = BORDER_NONE

        .BottomGap = 30

        ''''''''''''''''''''''''''''

        'X-Axis Setting

        .Axis(AXIS_X).Visible = True

        For i = 0 To chartSrc.XAxis.LabelCount - 1

            .Axis(AXIS_X).Label(i) = chartSrc.XAxis.Label(i)

        Next i

        .Axis(AXIS_X).Title = chartSrc.XAxis.Title

        'Series Setting

        .OpenDataEx COD_VALUES, chartSrc.NSeries, chartSrc.NValues

        For i = 0 To chartSrc.NSeries - 1

            'Legend

            .Series(i).Legend = RTrim(chartSrc.Series(i).Legend)

            'Value

            For j = 0 To chartSrc.NValues - 1

                .Series(i).Yvalue(j) = Val(chartSrc.Series(i).Yvalue(j))

                If .Series(i).Yvalue(j) > MaxYValue Then

                    MaxYValue = .Series(i).Yvalue(j)

                End If

            Next j

            .Series(i).MarkerShape = MK_CUBE

        Next i

        .CloseData COD_VALUES

        'SerLegBox Setting

        .SerLegBoxObj.Docked = TGFP_RIGHT

        .SerLegBoxObj.BkColor = RGB(255, 255, 255)

        .SerLegBoxObj.Visible = chartSrc.SerLegBox

        .SerLegBoxObj.AutoSize = True

        'Y-Axis Setting

        .Axis(AXIS_Y).Visible = True

        .Axis(AXIS_Y).Decimals = chartSrc.YAxis.Decimals

        .Axis(AXIS_Y).Title = chartSrc.YAxis.Title

        .RecalcScale

        .Width = picResult.Width - 3

        .Height = picResult.Height - 3

    End With

End Sub

Are you using the latest service pack ?

What is clsChartDefinedMyClassModule ? is that your own class ? how do you 

know the leak is not there ?

Can you provide us with a program that reproduces the problem without using 

any external class ?

I don't know what the lastest service pack is.

The version of Cfx4032.ocx is 4.0.19.0 and the version of SfxBar.dll is

1.0.20.0.

Are these the lastest one?

How can I get the lastest service pack?

I think my class has no memory leak problem.

I always "set nothing" whenever "set new".

And I've checked it in "for loop of 10000'th".

And if the source of the problem has been on memory leak other than ChartFX,

the error point would be changed.

But the error point was always on the function where I posted.

I downloaded the lastest service pack. 

After test, I'll post the result on here.

Thank you~
