Transfer Event

Fired while a document transfers (delivers document).


typedef struct {
  int Direction;
  __int64 BytesTransferred;
  int PercentDone;
  String Text;
  DynamicArray<Byte> TextB;
} Tis3S3ClientTransferEventParams;

typedef void __fastcall (__closure *Tis3S3ClientTransferEvent)(System::TObject* Sender, Tis3S3ClientTransferEventParams *e);

__property Tis3S3ClientTransferEvent OnTransfer = { read=FOnTransfer, write=FOnTransfer };


The Text parameter contains the portion of the document text being received. It is empty if data is being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
