access violation in module "Teechart8.ocx"

Hello

I use
1. October 2008 TeeChart Pro Activex Control v8 v8.0.0.5 Release
2. Win 7 prof
3. Microsoft VS 2008 C++ Win32 MFC SDI FormView


I receive the message

Access violation at address 04012C1A in module 'TeeChart8.ocx'. Read of adresses 00006ECC.
or
Access violation at address 03DEF7C0 in module 'TeeChart8.ocx'. Read of adresses 00001A88.
and addresses can be different in some limits

It happens sometime only when I restart thread after stop:

Code: Select all


//start and restart with this
wtPlotProc = AfxBeginThread(uiPlotProc,this);


UINT		CContView::uiPlotProc(LPVOID param)
{
	CContView *pdlg = static_cast<CContView *>(param);//pointer on mdi dialog
	if (pdlg == NULL || !pdlg->IsKindOf(RUNTIME_CLASS(CContView)))
		return 1;

              pdlg->m_ctrlChart1.RemoveAllSeries();
	pdlg->m_ctrlChart1.AddSeries(scLine);
	pdlg->m_ctrlChart1.AddSeries(scLine);
	pdlg->m_ctrlChart1.AddSeries(scPoint);
	
	pdlg->m_ctrlChart1.Series(0).SetShowInLegend(false);
	pdlg->m_ctrlChart1.Series(0).SetColor(RGB(0,100,200));
	pdlg->m_ctrlChart1.Series(0).GetAsLine().GetLinePen().SetWidth(1);
	pdlg->m_ctrlChart1.Series(1).SetShowInLegend(false);
	pdlg->m_ctrlChart1.Series(1).SetColor(RGB(200,20,0));
	pdlg->m_ctrlChart1.Series(1).GetAsLine().GetLinePen().SetWidth(2);
	pdlg->m_ctrlChart1.Series(2).SetShowInLegend(false);
	pdlg->m_ctrlChart1.Series(2).SetColor(RGB(20,200,20));
	pdlg->m_ctrlChart1.Series(2).GetAsPoint().GetPointer().SetStyle(psCircle);
	pdlg->m_ctrlChart1.Series(2).GetAsPoint().GetPointer().SetHorizontalSize(3);
	pdlg->m_ctrlChart1.Series(2).GetAsPoint().GetPointer().SetVerticalSize(3);
	pdlg->m_ctrlChart1.Series(2).AddXY(2048,0,"",RGB(20,200,20));

	pdlg->m_ctrlChart1.Series(0).SetName("Series0");

	pdlg->m_ctrlChart1.Series(0).AddArray(iFFTSize,YValues,XValues);
	pdlg->m_ctrlChart1.Series(1).AddArray(iFFTSize,YValues,XValues);

              ....
              CSeries lSeries = pdlg->m_ctrlChart1.Series(0);
              .....
              pdlg->m_ctrlChart1.Repaint();
	pdlg->m_ctrlChart1.Series(0).RefreshSeries();
	pdlg->m_ctrlChart1.Series(2).RefreshSeries();
              ...
              return 0;
}
I don't know where to search for an error
Could you direct me?

Thank you

Hi knk2,

Can you please check if latest TeeChart Pro v8 ActiveX maintenance release available at the client area solves the problem at your end? If it doesn't, could you please attach a simple example project we can run "as-is" to reproduce the problem here?

Thanks in advance.

Hello

Are you talk about "TeeChartAX8English.exe March 01, 2010 Build 8.0.0.8" ? Should I use this update?

Hi knk2,

Yes, that's it: Not necessarily the English build though, you can use TeeChart8ActiveX.exe too.

I will try to describe as I use teechart in the project.
I catch sometime access violation error in this simple example, when restart thread with OnBnClickedCap192() and OnBnClickedStopcap192() function

One question
Should I replace all teechart .cpp and .h files in my project by files from update, or replace only .ocx and .cab files ?

thank you

Hi knk2,

Yes, those files should be updated with each maintenance release.

It would also be very helpful if you tried to arrange a simple example project we can run "as-is" and let us know the exact steps we should follow to reproduce the problem here.

Thanks in advance.
