    property OnFilterAttachToFsVolume : TCbFltFilterAttachToFsVolumeEvent;
    TCbFltFilterAttachToFsVolumeEvent = procedure(Sender : TObject; VolumeName : TCBString) of object;

[C++ (Lib)]
    typedef void (*CbFltFilterAttachToFsVolumeEvent)(CallbackRegistry* Sender, LPCWSTR VolumeName);

[C++ (VCL)]
    typedef void __fastcall (__closure *TCbFltFilterAttachToFsVolumeEvent)(System::TObject* Sender, TCBString VolumeName);

[C++ (.NET)]
    public delegate void CbFltFilterAttachToFsVolumeEvent(CallbackRegistry^ Sender, String^ VolumeName);

    delegate void CbFltFilterAttachToFsVolumeEvent(CallbackRegistry Sender, String VolumeName);

    Delegate Sub CbFltFilterAttachToFsVolumeEvent(ByVal Sender As CallbackRegistry, ByVal VolumeName As String)


  • Sender - reference to the class that called the delegate/event handler
  • VolumeName - the name of the volume which has been mounted to the system


Use this event to be notified when new file system volume appears in the system. You can set filter rules on the new volume, if needed, in response to this event.
