LNK2019 error from cseriespointeritems

Post by DVT » Mon Dec 08, 2014 8:33 pm

It looks like this is a new classes in TeeChart2014.0.02. After I installed this new version, my project is broken. It didn't get compiled in VC2012 before I include "seriespointeritems.h" in my files. The code in question is:

m_Chart.Series(i).GetAsPoint().GetPointer().SetInflateMargins(false);
m_Chart.Series(i).GetAsLine().GetPointer().SetVisible(false);

It looks like GetPointer() now returns CSeriesPointerItems instead of CPointer as before. It gets compiled after "seriespointeritems.h" is included. However, some link errors come up:

Core_AnalyzerView.obj : error LNK2019: unresolved external symbol "public: void __thiscall CSeriesPointerItems::SetInflateMargins(int)" (?SetInflateMargins@CSeriesPointerItems@@QAEXH@Z) referenced in function "protected: void __thiscall CCore_AnalyzerView::SetPlotProperty(void)" (?SetPlotProperty@CCore_AnalyzerView@@IAEXXZ)

Core_AnalyzerView.obj : error LNK2019: unresolved external symbol "public: void __thiscall CSeriesPointerItems::SetVisible(int)" (?SetVisible@CSeriesPointerItems@@QAEXH@Z) referenced in function "protected: void __thiscall CCore_AnalyzerView::SetPlotProperty(void)" (?SetPlotProperty@CCore_AnalyzerView@@IAEXXZ)

Do I miss anything? I could not understand why GetAsPoint().GetPointer() returns a different type not kept consistent as before?

Just clear it out - in the previous post,

CTChart m_Chart;

And looks like series IPointer3DSeries.Pointer is kept the same as before but ICUstomSeries.Pointer (series line and point) are changed to type ISeriesPointerItems.

Hello,

What TeeChart version are you coming from?
This change was applied in TeeChart VCL v2013.09 (note TeeChart ActiveX is a TeeChart VCL wrapper) and it was explained in the Whats New page:
Line, Area, Point Series (and derived series from TCustomSeries)
  • New Pointer.Items property

    Series Pointers can now be customized individually, for example:

    Code: Select all

    Series1.Pointer.Items[12].Color := clRed
    
    Series1.Pointer[34].Visible := False
    When a pointer item has been modified, changes to the global Series1.Pointer property will not be used.

    To reset a pointer item to its default values, set to nil:

    Code: Select all

    Series1.Pointer[12] := nil
    To remove all custom pointer items completely, call Clear:

    Code: Select all

    Series1.Pointer.Clear

I upgraded my projects to TeeChart2014 from an earlier TeeChart version than v2013. I defined CPointer variables to store the returned values from GetPointer(); the function in the latest version returns CSeriesPointerItems which causes my project failure during compile. After I changed my code, everything is OK now. However, it was not a good idea to change the return type of any existing functions.

I see. I'm sorry for the inconvenience generated.

Please show me the detail solutions.

Original code using V8
c_Chart.Series(0).GetAsLine().GetPointer().SetHorizontalSize(2);
c_Chart.Series(0).GetAsLine().GetPointer().SetVerticalSize(2);

How to fix in V2014 ?

Hello,

In a new MFC project following the instructions here, I can create a LineSeries, make the Pointer Visible and change its Pointer HorizontalSize and VerticalSize with the following code:

Code: Select all

#include "CSeries.h"
#include "CLineSeries.h"
#include "CPointer.h"
//...
void CMFCApplication1Dlg::initChart()
{
	//...
	mChart1.AddSeries(0);
	CSeries s = mChart1.get_aSeries(0);
	s.FillSampleValues(10);

	CLineSeries ls = s.get_asLine();
	CPointer pls = ls.get_Pointer();
	pls.put_Visible(true);
	pls.put_HorizontalSize(2);
	pls.put_VerticalSize(2);
}

Thanks.

But I am porting old projects using TeeChart OCX from V8 to V2014, not creating new project.
I want to know how to modify the making-trouble "GetPointer()" function to made the existing project working as before.

The customer above, "DVT", solved this changing the return type of GetPointer() from CPointer to CSeriesPointerItems:

Have you tried this?
Actually, in the new application I mentioned in my last post, changing the return type of GetPointer() from CPointer to CSeriesPointerItems also works:

Code: Select all

#include "CSeries.h"
#include "CLineSeries.h"
//#include "CPointer.h"
#include "CSeriesPointerItems.h"
//...
void CMFCApplication1Dlg::initChart()
{
   //...
   mChart1.AddSeries(0);
   CSeries s = mChart1.get_aSeries(0);
   s.FillSampleValues(10);

   CLineSeries ls = s.get_asLine();
   //CPointer pls = ls.get_Pointer();
   CSeriesPointerItems pls = ls.get_Pointer();
   pls.put_Visible(true);
   pls.put_HorizontalSize(2);
   pls.put_VerticalSize(2);
}
If you still find problems with it, please try to arrange a simple example project we can run as-is to reproduce the problem here.
