hello all friends

I arduino user from thailand. I am a newbie about arduino ( and C++ ) I use Eternet shield "ENC28j60" + Arduino board "ATmega328"
Now I try to programming command MCU send ICMP echo request from destination IP and Check Replay from Destination but not work...
All my friend please help me how to resolve problem please see below code where is wrong why not work. when i compile this code have error message "'class EtherShield has no member named 'ES_packetloop_icmp_checkreply'" but when i open files EtherShield.h I can see this class...

plese help me for this topic

  1. how to send icmp echo ping request to destination ip ( please show exam code )
  2. how to check replya echo icmp from destination ip ( please show exam code )

}

I went to this site:
http://www.nuelectronics.com/estore/index.php?main_page=project_eth
and downloaded the etherShield library. I opened the etherShield.h file there:

Perhaps it's a poor eyesight problem, but I don't see a member called ES_packetloop_icmp_checkreply.

So, where did you get YOUR library from?

in update version ( include twitter.h ) have class icmp_request and replay please see this below

Anyway, Please help me how to call class to work

So, did you use

#define PING_client

anywhere?
