<ul>
EWDPing is a sample program which illustrates the use of the
<a href="http://www.earthwalkdesigns.com/EWSoftware/CIcmp">CIcmp</a> class to
provide access to RAW sockets and ICMP (Internet Command Message Protocol).
<p>
This program implements the ICMP <b>Echo Request</b> message (commonly
known as PING) to check the on-line status of an Internet host, and TTL to
trace the route to the Internet host.
<p>
The <i>.zip</i> file contains the source for EWDPing as well as the source for
the EarthWalk Design classes:
<p>
<ul>
<b><a href="http://www.earthwalkdesigns.com/EWSoftware/CIcmp">CIcmp</a></b>,
<br>
<b><a href="http://www.earthwalkdesigns.com/EWSoftware/CRegKey">CRegKey</a></b>
and
<br>
<b><a href="http://www.earthwalkdesigns.com/EWSoftware/CSysTCPIP">CSysTCPIP</a></b>.
</ul>
<p>
The program also makes use of a system timer to prevent "hanging" on a
non-responsive gateway. Timer operations are discussed in the
<a href="http://www.earthwalkdesigns.com/EWSoftware/Tutorials/Timers">
MFC Timers</a> tutorial.
<p>
This is a demonstration program and, as such, probably contains some
logic flaws. There are still a number of functions which could be added
to improve the user interface, but that was not the purpose of this program.
Its' sole purpose is to demonstrate the useage of the <b>CIcmp</b> class.
<p>
Documentation for the functions and variables are presented within the
programs' source.
