class AcDbOleFrame : public AcDbFrame;
dbole.h
This class provides support for pre-R13c4 OLE 1 retrieval only. It exists only to allow reading in old pre-R13c4 drawings that contained OLE 1 objects. When such objects are read in, the user is asked if she'd like to convert them to OLE 2, at which point they are converted to AcDbOle2Frame objects. All new OLE objects inserted, pasted, or dragged-and-dropped are AcDbOle2Frame.
