BeforeCloseFile Event

Fires before a file or directory is closed.

Syntax

type TBeforeCloseFileEvent = procedure (
  Sender: TObject;
  const FileName: String;
  var FileContext: Pointer;
  var HandleContext: Pointer;
  var ResultCode: Integer
) of Object;

property OnBeforeCloseFile: TBeforeCloseFileEvent read FOnBeforeCloseFile write FOnBeforeCloseFile;

Remarks

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.
