ping.exe命令的简单运用的简单问题请教！

Question

我想实现的是：怎么样可以ping一个ip，然后把它返回的相关信息保存到一个文件
中！！！！！！！！！！！！！！！！！！！！！！！！！谢谢！可不可以用winexec类似这种命令来使用ping.exe实现！
如果有简单的例子，万分感谢！

呵呵,为你写了一个程序,实现ping功能:#include <iostream.h>
#include <winsock2.h>
#include <ws2tcpip.h>
typedef struct {
   unsigned char Ttl;                                           // Time To Live
   unsigned char Tos;                                        // Type Of Service
   unsigned char Flags;                                      // IP header flags
   unsigned char OptionsSize;                  // Size in bytes of options data
   unsigned char *OptionsData;                       // Pointer to options data
} IP_OPTION_INFORMATION, * PIP_OPTION_INFORMATION;typedef struct {
DWORD Address;                                           // Replying address
   unsigned long  Status;                                       // Reply status
   unsigned long  RoundTripTime;                         // RTT in milliseconds
   unsigned short DataSize;                                   // Echo data size
   unsigned short Reserved;                          // Reserved for system use
   void *Data;                                      // Pointer to the echo data
   IP_OPTION_INFORMATION Options;                              // Reply options
} IP_ECHO_REPLY, * PIP_ECHO_REPLY;int doit(int argc, char* argv[])
{
    // Check for correct command-line args
    if (argc < 2) {
        cerr << "usage: ping " << endl;
        return 1;
    }
    // Load the ICMP.DLL
    HINSTANCE hIcmp = LoadLibrary("icmp.DLL");
    if (hIcmp == 0) {
        cerr << "Unable to locate ICMP.DLL!" << endl;
        return 2;
    }
    // Look up an IP address for the given host name
    struct hostent* phe;
    if ((phe = gethostbyname(argv[1])) == 0) {
        cerr << "Could not find IP address for " << argv[1] << endl;
        return 3;
    }
    // Get handles to the functions inside ICMP.DLL that we'll need
    typedef HANDLE (WINAPI* pfnHV)(VOID);
    typedef BOOL (WINAPI* pfnBH)(HANDLE);
    typedef DWORD (WINAPI* pfnDHDPWPipPDD)(HANDLE, DWORD, LPVOID, WORD,
            PIP_OPTION_INFORMATION, LPVOID, DWORD, DWORD); // evil, no?
    pfnHV pIcmpCreateFile;
    pfnBH pIcmpCloseHandle;
    pfnDHDPWPipPDD pIcmpSendEcho;
    pIcmpCreateFile = (pfnHV)GetProcAddress(hIcmp,
            "IcmpCreateFile");
    pIcmpCloseHandle = (pfnBH)GetProcAddress(hIcmp,
            "IcmpCloseHandle");
    pIcmpSendEcho = (pfnDHDPWPipPDD)GetProcAddress(hIcmp,
            "IcmpSendEcho");
    if ((pIcmpCreateFile == 0) || (pIcmpCloseHandle == 0) ||
            (pIcmpSendEcho == 0)) {
        cerr << "Failed to get proc addr for function." << endl;
        return 4;
    }
    // Open the ping service
    HANDLE hIP = pIcmpCreateFile();
    if (hIP == INVALID_HANDLE_VALUE) {
        cerr << "Unable to open ping service." << endl;
        return 5;
    }
    // Build ping packet
    char acPingBuffer[64];
    memset(acPingBuffer, '\xAA', sizeof(acPingBuffer));
    PIP_ECHO_REPLY pIpe = (PIP_ECHO_REPLY)GlobalAlloc(
            GHND, sizeof(IP_ECHO_REPLY) + sizeof(acPingBuffer));
    if (pIpe == 0) {
        cerr << "Failed to allocate global ping packet buffer." << endl;
        return 6;
    }
    pIpe->Data = acPingBuffer;
    pIpe->DataSize = sizeof(acPingBuffer);
    // Send the ping packet
    DWORD dwStatus = pIcmpSendEcho(hIP, *((DWORD*)phe->h_addr_list[0]),
            acPingBuffer, sizeof(acPingBuffer), NULL, pIpe,
            sizeof(IP_ECHO_REPLY) + sizeof(acPingBuffer), 5000);
    if (dwStatus != 0) {
        cout << "Addr: " <<
                int(LOBYTE(LOWORD(pIpe->Address))) << "." <<
                int(HIBYTE(LOWORD(pIpe->Address))) << "." <<
                int(LOBYTE(HIWORD(pIpe->Address))) << "." <<
                int(HIBYTE(HIWORD(pIpe->Address))) << ", " <<
                "RTT: " << int(pIpe->RoundTripTime) << "ms, " <<
                "TTL: " << int(pIpe->Options.Ttl) << endl;
    }
    else {
        cerr << "Error obtaining info from ping packet." << endl;
    }
    // Shut down...
    GlobalFree(pIpe);
    FreeLibrary(hIcmp);
    return 0;
}
int main(int argc, char* argv[])
{
    WSAData wsaData;
    if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
        return 255;
    }
    int retval = doit(argc, argv);
    WSACleanup();
    return retval;
}
记得要将icmp.dll拷贝至你的工程目录下.如果你的程序名为aa,
那么先运行dos控制台(CMD),然后运行aa zhucde就会显示出IP地址等其它信息.
从程序中可以看出:
 cout << "Addr: " <<
                int(LOBYTE(LOWORD(pIpe->Address))) << "." <<
                int(HIBYTE(LOWORD(pIpe->Address))) << "." <<
                int(LOBYTE(HIWORD(pIpe->Address))) << "." <<
                int(HIBYTE(HIWORD(pIpe->Address))) << ", " <<
                "RTT: " << int(pIpe->RoundTripTime) << "ms, " <<
                "TTL: " << int(pIpe->Options.Ttl) << endl;
这段程序显示了信息,你只要将这些信息保存起来存成文件就行了,
这个工作就不给你做了(以上程序已经测试成功)祝你好运,有什么问题给我留言.(附上帖子地址)

Answer 2

你只要建一个空的工程,把文件全删了,加入此cpp编译就行(或者我可以把我编译好的工程发给你)

Answer 3

ping 1.2.3.4>>result.txt
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
这样的话，就不能把ping命令所有返回的信息分开了！

Answer 4

请教：
  我将你给我的那个函数使用到一个定时器里面，可是如果我连续做3次，就会返回3
即：if ((phe = gethostbyname(argv[1])) == 0) {
        cerr << "Could not find IP address for " << argv[1] << endl;
        return 3;
    }
但是我给的那个ip地址是正常的，应该返回0的，请问为什么阿？
再就是返回2到底是什么意思？
谢谢帮助！
