I need to  delete (erase) all unused AcDbAnnotationScales from ContextCollection, but i did not find any method like delete or erase ...

How to do it?

Thanks.

AcString annoName(_T("Scale 1:125"));
AcDbObjectContextManager *cManager = acdbCurDwg()->objectContextManager();
AcDbObjectContextCollection *col = cManager->contextCollection(ACDB_ANNOTATIONSCALES_COLLECTION);
col->removeContext(annoName);
