The OnEcho event is generated when a packet is sent to the remote
Sub object_OnEcho( [Index As
Integer,] ByVal SequenceId As Variant,
ByVal RemoteHost As Variant, ByVal
PacketSize As Variant )
The OnEcho event is generated for non-blocking sockets when
an ICMP echo datagram is sent to the remote host. This event is only
generated when the Blocking property is set to False. The
following arguments are passed to the event handler:
- An integer which specifies the packet sequence number, which is
used to uniquely identify each packet that is sent to the remote
host. This value will increase for each ICMP echo datagram that is
sent until the remote host address is changed. Once a new remote
host is specified, the sequence number is reset.
- A string which specifies the host name or IP address that the
echo datagram was sent to.
- An integer which specifies the size of the ICMP echo datagram
that was sent to the remote host.
