Annotation Objects in C++ won't show on chart

[User (Legacy)]

I'm trying to place a grid of text boxes across my chart in arbitrary

positions.  I think I've got the code in correctly, using ArticleID:Q1371016

as my guideline.  My problem is that the objects are never showing up on the

chart.  I'm using WTL for the windowing and have the chart on a property

page.

/* Here's the source I'm using to initialize the annotation objects */

// In header: AnnotateX::IAnnListPtr m_pAnnList;

// I pulled the GUID from the .tlh because __uuidof( AnnotateX::AnnotateX )

was not working

// this way it appears to be creating properly and giving a valid pointer.

   m_pAnnList.CreateInstance("{ef600d71-358f-11d1-8fd4-00aa00bd091c}");

   m_pAnnList->ToolBar = FALSE;

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

/* And here's the code I'm using to display a test text box */

// declare the object

   IAnnTextPtr pTextTest;

// create it (and add it to the chart?)

   pTextTest = m_pAnnList->Add((short) AnnotateX::OBJECT_TYPE_TEXT);

// set some sample properties

   pTextTest->Text = (BSTR) CComBSTR( "Test!" );

   pTextTest->Top = .5 * m_dy;

   pTextTest->Left = 3 * m_dx;

   pTextTest->Width = m_dx;

   pTextTest->Height = .5 * m_dy;

   pTextTest->Color = RGB( 0x00, 0x00, 0x00 );

   pTextTest->BkColor = CHART_TRANSPARENT;

   pTextTest->SizeToFit();

   pTextTest->Refresh( VARIANT_FALSE );

Thanks!

Nevermind - I found the problem.

It seems that when you call

m_pFX->ClearData( CD_ALLDATA );

it also removes any extensions added with AddExtension();

Basically I just need to change the order of my initialization.
