StartByte Property

The byte index of the position where the transfer should start.

Object Oriented Interface

public function getStartByte();
public function setStartByte($value);

Procedural Interface

ipworkssmime_simap_get($res, 98 );
ipworkssmime_simap_set($res, 98, $value );

Default Value



StartByte and EndByte are used together with the FetchMessagePart method to specify the portion of the message part to be retrieved from the server.

When StartByte or EndByte contain values other than the defaults (0), only the corresponding portion of the message part is retrieved from the server.

Byte indexes start from 1. The default value for EndByte is 0, which corresponds to the end of the message.

This property is not available at design time.
