Synchronously informs about a new file system volume


    property OnFilterAttachToFsVolumeC : TCBFSFltFilterAttachToFsVolumeEventC;
    TCBFSFltFilterAttachToFsVolumeEventC = procedure(Sender : TObject; VolumeName : TCBString) of object;

[C++ (Lib)]
    typedef void (*TCBFSFltFilterAttachToFsVolumeEventC)(CBFSFilter* Sender, LPCWSTR VolumeName);

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

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

    delegate void CBFSFltFilterAttachToFsVolumeEventC(CBFSFilter Sender, String VolumeName);

    Delegate Sub CBFSFltFilterAttachToFsVolumeEventC(ByVal Sender As CBFSFilter, 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 synchronous 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. Use ProcessMountVolumeEvent property to select, which kind of callback / event handler is called when the filter is attached or detached.

Error handling

See Error handling topic for detailed information about how to report errors, which occur in the event handlers, back to CBFSFilter.
