Fires when a file's size information has been retrieved.
type TNotifyGetFileSizesEvent = procedure ( Sender: TObject; const FileName: String; Size: Int64; AllocationSize: Int64; Status: Integer; var ResultCode: Integer ) of Object;
property OnNotifyGetFileSizes: TNotifyGetFileSizesEvent read FOnNotifyGetFileSizes write FOnNotifyGetFileSizes;
This event fires when size information has been retrieved for the file specified by FileName.
The Size parameter reflects the actual size of the file, in bytes.
The AllocationSize parameter reflects the amount of space allocated for the file, in bytes.
The Status parameter contains an NT status code that indicates the outcome of the operation; 0 indicates success. To convert this value to a Win32 error code, call the NtStatusToWin32Error method. Please note that this event won't fire for failed requests unless the ProcessFailedRequests property is enabled.
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, set it to a non-zero value to report an appropriate error. Note, however, that this event fires after the operation has already completed, so reporting an error won't actually affect the operation itself. Please refer to the Error Reporting and Handling topic for more information.
This event is fired asynchronously; please refer to the Event Types topic for more information.
