基于c的网络管理软件：ICMP协议，ping命令，运行界面及源代码-C-based network management software: ICMP protocol, ping command, run interface and source code

微软的ping命令的VC++源代码!比较容易理解-Microsoft' s ping command VC++ source code! Easier to understand

用delphi编写的实现ping的源码，编译后可直接运行，采取icmp组件实现-Delphi prepared with the ping source code, the compiler can be run directly, to take ICMP components to achieve
