What about this scenario,

- Client Create Object A
- Client Call an Object A Method
- Object A Create Object B
- Object A Calls an Object B Method
- Object B Encounter an error
- Object B Returns control to the client with ComReturnError()

Object A will still be active and is not aware of the problem of Object B, So what append in this case ?


>IMO, the best approach is to have a garbage collection method. Call it anytime you need to cleanup. Then call COMRETURNERROR(). The problems you cited are NOT due to COMRETURNERROR(), they are due to not doing proper cleanup.
