hi all,

i am writing a simple ping application using the
following calls

hIcmp = IcmpCreateFile(); // returns a handle to hIcmp
IcmpSendEcho(,,,,,,);  // sends and receives request 

IcmpCloseHandle(hIcmp); // closes the handle

now these require the icmp.dll, icmpapi.h & ipexport.h


i downloaded the two header files (icmpapi.h &
ipexport.h ) and included the icmp.dll by going to the
project->settings->link tab.

now while building this i get linker error saying
"Unresolved external Symbol"

error LNK2001: unresolved external symbol "int
__stdcall IcmpCloseHandle(void *)"
(?IcmpCloseHandle@@YGHPAX@Z)

error LNK2001: unresolved external symbol "unsigned
long __stdcall IcmpSendEcho(void *,unsigned long,void
*,unsigned short,struct ip_option_information *,void
*,unsigned long,unsigned long)"
(?IcmpSendEcho@@YGKPAXK0GPAUip_option_info
rmation@@0KK@Z)

error LNK2001: unresolved external symbol "void *
__stdcall IcmpCreateFile(void)"
(?IcmpCreateFile@@YGPAXXZ)

Can someone please help !!!

thanx a lot for the time you may spend

Regards
Amit Srivastava
