Re: Annotation object

[User (Legacy)]

Hi Juan, 

I have performed the following test: 

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

HRESULT hr; 

IAnnListPtr pAnnotationList; 

hr = m_pChartFX->raw_GetExtension(bstrExtensionName, 

(IUnknown**)&pAnnotationList); 

CLSID clsID; 

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 

CO_E_CLASSSTRING error. 

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 

extension) 

- 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 

appear. 

This happens on all PCs I have tested. 

Please help!
