User (Legacy) Posted February 2, 2000 Report Share Posted February 2, 2000 Good Morning! I have a small problem when using annotation objects in VC++. I am creating the objects using the information provided in Q1371016 "How to use Annotation Objects in VC++). I want to be able to use GetExtension and RemoveExtension. So using the example provided in the Chart 98 Help File, and use the following code: IAnnListPtr pAnnList; try { pAnnList = chartfx->GetExtension("AnnotateX.AnnList"); } catch (...){} The GetExtension call will always throw an exception. The RemoveExtension call does the same thing. I tried using the code: pAnnList2.CreateInstance(__uuidof(AnnotationX)); pAnnList = chartfx->GetExtension((IUnknown *)pAnnList2); but this gives me an error while compiling (which I can't seem to get by). I want to be able to just GetExtension and RemoveExtension. How can I do this? Thank you in advance. -- Josh Eanes Link to comment Share on other sites More sharing options...
