Classes Used

CIcmp

An object class derived from the MFC CSocket object class to provide access to RAW sockets and ICMP (Internet Control Message Protocol) functions.

CRegKey

An object class to provide to WindowsNT/95 system registry objects.

CSysTCPIP

An object class to provide access to some of the TCP/IP related information stored in the system registry on Windows NT using Microsoft's Winsock 2 interface.

Overview

EWDPing is a sample program which illustrates the use of the CIcmp class to provide access to RAW sockets and ICMP (Internet Command Message Protocol).

This program implements the ICMP Echo Request 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.

The .zip file contains the source for EWDPing as well as the source for the EarthWalk Design classes:

CIcmp,
CRegKey and
CSysTCPIP.

The program also makes use of a system timer to prevent "hanging" on a non-responsive gateway. Timer operations are discussed in the MFC Timers tutorial.

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 CIcmp class.

Documentation for the functions and variables are presented within the programs' source.
