vcping源码

㈠ C#源代码。数据包互ping 相互ping包

C#是一种安全的、稳定的、简单的、优雅的，由C和C++衍生出来的面向对象的编程语言。它在继承C和C++强大功能的同时去掉了一些它们的复杂特性（例如没有宏和模版，不允许多重继承）。

㈡ 求windows下ping程序c源代码，模拟的ping也行，能编译通过就行，网上很多通不过

㈢ vc6++网络编程 编写一个ping程序，测试本局与的所有机器是否在线

古色古香里应外合mq鲉欢喜雀跃的妞阿雅KL

㈣ C/C++编写一个 Ping 程序,并能测试本局域网的所有机器是否在线

//关键代码如下：
#include "icmpapi.h"
#include "iphlpapi.h"

#pragma comment(lib,"iphlpapi.lib");

bool CPINGDlg::startping(char* IP) //成功返回true, 失败返回false
{
HANDLE hIcmpFile = NULL;
unsigned long ipaddr = INADDR_NONE;
DWORD dwRetVal = 0;
char SendData[] = "Data Buffer\0";
LPVOID ReplyBuffer = NULL;
DWORD ReplySize = 0;
// PICMP_ECHO_REPLY reply;
ipaddr = inet_addr(IP);
ReplySize = sizeof(ICMP_ECHO_REPLY)+sizeof(SendData);
ReplyBuffer = (void*)malloc(ReplySize);
hIcmpFile = IcmpCreateFile();
if (hIcmpFile == INVALID_HANDLE_VALUE)
{
AfxMessageBox(_T("Ping 内部代码错误"));

return false;
}
dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData), NULL, ReplyBuffer, ReplySize, 1000);

if (dwRetVal != 0)
{
return true;

return false;
}
}

㈤ 这个易语言ping源码 谁能给下 谢谢啦 就是把IP地址输入 下面返回 PING的值。 代码不知道怎么写。

.版本 2
.如果 (编辑框1.内容 ≠ “”)
运行 (“cmd /c ping ” ＋ 编辑框1.内容 ＋ “-t” ＋ “ >c:\ping.txt”, 真, #隐藏窗口)
编辑框2.内容 ＝ 到文本 (读入文件 (“c:\ping.txt”))
删除文件 (“c:\ping.txt”)
.否则
.如果结束
是用CMD的保存文件。读取CMD的保存文件。原理就是这样

㈦ 有高手帮忙解决VC++，做一个能ping的软件么代码分享下

ping.c 可以从微软获得。
http://research.microsoft.com/en-us/um/redmond/projects/invisible/src/games/ping/ping.c.htm

只要 本机 主机名和IP：
system("ipconfig");

㈧ 怎样用C++实现cmd窗口中的ping 程序谢谢高手

你可以调用系统的ping程序啊。用system(),或者exec(),C++我不太懂，在java里面调用Runtime类执行ping命令之后可以获得一个输入流，把ping的结果读进来做判断，不知道C++里面可不可以这么做，你查查函数库吧，应该有的

㈨ 用C#写一个类似cmd的控制台程序，实现ping的功能！！！（求完整程序源代码！）

using System;
using System.Net;
using System.Net.NetworkInformation;
class Program
{
static void Main(string[] args)
{
int count = 4;
IPAddress addr = IPAddress.Parse("220.181.111.86");
Ping ping = new Ping();
long timeSum = 0;
int succCount = 0;
//发送
Console.WriteLine("正在ping {0}", addr);
for (int i = 0; i < count; ++i)
{
PingReply pr = ping.Send(addr);
if (pr.Status == IPStatus.TimedOut)
Console.WriteLine("超时");
else if (pr.Status == IPStatus.Success)
{
Console.WriteLine("延时：{0}毫秒", pr.RoundtripTime);
++succCount;
timeSum += pr.RoundtripTime;
}
}
if (timeSum != 0)
Console.WriteLine("平均延时{0}毫秒，丢包率{1}%", 1.0 * timeSum / succCount, (count - succCount) * 100.0 / count);
else
Console.WriteLine("丢包率100%");
return;
}
}
