明白delphi的来看看

idicmpclient1.ping()命令会有反馈

reply事件就是idicmpclient控件获得反馈后响应事件

Treplystatus在delphi中的描述是：

TReplyStatus = record

BytesReceived: integer// number of bytes in reply from host

FromIpAddress: string // IP address of replying host

MsgType: byte

SequenceId: word // sequence id of ping reply

// TODO: roundtrip time in ping reply should be float, not byte

MsRoundTripTime: longword// ping round trip time in milliseconds

TimeToLive: byte // time to live

ReplyStatusType: TReplyStatusTypes

end

reply事件就是返回这些参数值的，比如从主机获得的字节数等。
