BeforeCloseFile Event

Fires before a file or directory is closed.


typedef struct {
  String FileName;
  void* FileContext;
  void* HandleContext;
  int ResultCode;
} TcbfCBFilterBeforeCloseFileEventParams;

typedef void __fastcall (__closure *TcbfCBFilterBeforeCloseFileEvent)(System::TObject* Sender, TcbfCBFilterBeforeCloseFileEventParams *e);

__property TcbfCBFilterBeforeCloseFileEvent OnBeforeCloseFile = { read=FOnBeforeCloseFile, write=FOnBeforeCloseFile };


This event fires before the file or directory specified by FileName is closed.

Applications only need to handle this event if they've added a standard filter rule that includes the FS_CE_BEFORE_CLOSE flag.

The FileContext and HandleContext parameters are placeholders for application-defined data associated with the file and specific handle, respectively. Please refer to the Contexts topic for more information.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.

This event is fired synchronously; please refer to the Event Types topic for more information.
