IcmpSendEcho error: 1231
-
I got 1231 error value when using the code below. 1231: The network location cannot be reached. For information about network troubleshooting, see Windows Help. my lan and internet is working fine. then where is actually the problem residing.
HANDLE hIcmpFile;
unsigned long ipaddr = INADDR_NONE;
DWORD dwRetVal = 0;
char SendData[] = "Data Buffer";
LPVOID ReplyBuffer = NULL;
DWORD ReplySize = 0;ipaddr = inet_addr((const char*)m_sAddress);
ReplySize = sizeof(ICMP_ECHO_REPLY) + sizeof(SendData) +1;
ReplyBuffer = (VOID*)malloc(ReplySize);hIcmpFile = IcmpCreateFile();
if (hIcmpFile == INVALID_HANDLE_VALUE)
{
return -1;
}
dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData) + sizeof(ICMP_ECHO_REPLY), NULL, ReplyBuffer, ReplySize, 500);
if(dwRetVal != 0)
{
PICMP_ECHO_REPLY pEchoReply = (PICMP_ECHO_REPLY)ReplyBuffer;
struct in_addr ReplyAddr;
ReplyAddr.S_un.S_addr = pEchoReply->Address;m\_sMessage.Format(\_T("Received from %s Status = %ld RoundTripTime = %ld"), inet\_ntoa(ReplyAddr), pEchoReply->Status, pEchoReply->RoundTripTime); return 0; }Future Lies in Present. Manmohan Bishnoi

If you want to use ping from your application, have a look at boost::asio. Boost have a ping example program that you may be able to adopt. Note that your application requires administrative privileges on Vista to create ICMP packets. Regards, Sternocera

yes same for all IP's. My OS is Windows Seven RC. I have also tested this on XP. There also the problem is same.
