hi

i want to make a trace route program in vb. i know how to make it but i don't know how to ping.

i know you have to use icmp.dll but i don't know how you use it.

some of the properties i need to be able to set/return:

  • change TTL of the packet
  • return ip of the computer sending the return packet
  • change buffer size
  • resolve ips to hostnames and vice versa
  • return the round-trip time (in milliseconds)
  • change time-out time



the reason i want to make a trace route program is that i got a few shareware programs already but they have expired so i thought if i made one, i could make it freeware.

i've also got another question what does Type Of Service do?

thank you
