I need Delphi 4 sources (no components without sources, please) for a little ping function using WinSock2 (no ICMP.DLL, please).
Thank you...  :-)

Regards, Madshi.

BlackMan,

thanx for your answer. Unfortunately Andreas' components are based on WinSock(1) and the "ICMP.DLL". Look at this extract from one of his units:

{ Microsoft doesn't support the standard way ICMP is implemented using
  sockets, that means by the SOCK_RAW socket type - they only work as
  user administrator! And there's no way to set the TTL for the packets, so
  there's no way to build a TraceRoute using winsock. So this unit uses their
  ICMP.DLL, although MS discourages it's use - once they have a better solution
  this properitary implementation will vanish. So be careful where you
  use this unit! }

With WinSock2 Microsoft DOES support SOCK_RAW. So I need an implementation of ping for WinSock2.

Sorry, Madshi.

I think that is a "general" comment-cut from the WinSock site, the history.txt says:
1997-07-02  0.2  added support for winsock ICMP calls (TPing only yet)
And if you look at the TPing component in ICMP.PAS, it look like it has a socket-mode..
