Exporting an Annotation List with a Graph

[User (Legacy)]

I've created an annotation list which I attach to my ChartFX pointer.

   IChartFXPtr m_pFX;

   IAnnListPtr m_pAnnList; // annotations

   m_pAnnList.CreateInstance(__uuidof( AnnotationX ));

   m_pAnnList->CFX98_ToolBar = FALSE;

   m_pFX->AddExtension((IUnknown *)m_pAnnList);

I then create data region labels which I store in an array.

   IAnnTextPtr regionLabels[50];

  // Loop through 50 times

      regionLabels[i] = m_pAnnList->Add((short) OBJECT_TYPE_TEXT);

I've created an array of gridlines with IAnnArrowPtr similarly.

My problem is that I've been attempting to export this graph setup so that I

can simply reimport it in an ActiveX control without having to reimplement

the code.  I've used the following export/import functions while I've been

testing it.

HRESULT hr = m_pFX->Export( CHART_CFXOLEFILE, CComVariant(

CComBSTR("D:\\dutycycle.chd") ) );

HRESULT hr = m_pFX->Import( CHART_CFXOLEFILE, CComVariant(

CComBSTR("D:\\dutycycle.chd") ) );

The array of IAnnArrowPtrs has exported and imported without any problems.

However, the array of IAnnTextPtr does not seem to be exporting/importing

correctly.  I placed the export command at the end of my initialization

function after I had created everything.  I then replaced the initialization

function with the import command.  Unfortunately when I attempted to update

the array of IAnnTextPtrs with data, my program threw an error.

Is the IAnnTextPtr in fact successfully importing and exporting?  Is my

problem the fact that I need to somehow reattach the IAnnTextPtr that was

imported back to my member variable?  Should I simply recreate that array

and not worry about trying to import and export it?

Thanks,

Yes, your member variable can not be affected by the chart import.

Do the text appear in the chart ? if so, they were imported correctly you

have to then call GetExtension to get a pointer to the SAVED annotation list

and then go through it.
