Annotation GetExtension throwing exception

User (Legacy)

Recommended Posts

I am trying to create a chart with an annotation toolbar dynamically.  I use 

the following code:



pAnnList = chartfx->GetExtension("AnnotationX.AnnList");





HRESULT rs = chartfx->AddExtension((IUnknown *)pAnnList);


Everytime that I call a chart that does not have an annotation object, it

wil throw a C++ Exception. The Try Catch seems to handle it, but I was

wondering if this exception was normal for a GetExtension call?
