OLE Drag Drop Question

I'm using the Janus Systems Button Bar control, but it doesn't have any OLE Drag Drop events (i.e. OLECompleteDrag, OLEDragDrop, OLEDragOver, OLEGiveFeedback, OLESetData and OLEStartDrag).

Is it posible to detect OLE Drag Drop events on a control that doesn't have OLE Drag Drop VB event. Subclassing maybe?

Thanks in advance
:)
