Re: Annotation object

Hi Juan, 

I have performed the following test:

bstr_t bstrExtensionName = _T("AnnotationX.AnnList");


IAnnListPtr pAnnotationList;

hr = m_pChartFX->raw_GetExtension(bstrExtensionName,



hr = CLSIDFromProgID(bstrExtensionName, &clsID);

raw_GetExtension() returns an error, CO_E_CLASSSTRING, but CLSIDFromProgID()

returns S_OK !!! (and clsID is set to

{EF600D71-358F-11D1-8FD4-00AA00BD091C} )

That is, the success of CLSIDFromProgID identifies that the registry

settings are ok. I have also checked that using regedit.

I tried raw_GetExtension("AnnotationX.AnnList"),

raw_GetExtension("AnnotationX.AnnList.1") with no luck, still


I am using ChartFX DLL.

The full sequence of actions is:

- create chartfx control (CreateInstanceLic)

- load it from the file using Import method (this may load an already saved


- call GetExtension to determine if I have to make AddExtension

- create chart window (CreateWnd)

Annotation extension works fine (after AddExtension) but GetExtension always

returns an error. As a result 2 extension are added and 2 extension toolbars


This happens on all PCs I have tested.

Please help!
