为什么编译说找不到PIP_ADAPTER_ADDRESSES定义? 我明明已经加了头文件了

[werjkk]

#include "stdafx.h"
#include "GetMAC_mfc.h"
#include <Iphlpapi.h>
#pragma comment(lib,"Iphlpapi")
CWinApp theApp;
using namespace std;
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
	int nRetCode = 0;
    PIP_ADAPTER_ADDRESSES *  pAddresses = NULL;
    PIP_ADAPTER_ADDRESSES *  pCurrAddresses = NULL;
    ULONG family=AF_UNSPEC;
    ULONG flags = GAA_FLAG_INCLUDE_PREFIX;
    
    ULONG outBufLen = sizeof( PIP_ADAPTER_ADDRESSES  );
    pAddresses = (PIP_ADAPTER_ADDRESSES )HeapAlloc(GetProcessHeap(), 0, outBufLen );

    if (GetAdaptersAddresses(family, flags, NULL, pAddresses, &outBufLen) == ERROR_BUFFER_OVERFLOW)
    {
        HeapFree(GetProcessHeap(), 0, pAddresses );
        pAddresses = (IP_ADAPTER_ADDRESSES *)HeapAlloc(GetProcessHeap(), 0, outBufLen );
    }
    printf("address = %s\n",pAddress);
	// initialize MFC and print and error on failure
	if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
	{
		// TODO: change error code to suit your needs
		_tprintf(_T("Fatal Error: MFC initialization failed\n"));
		nRetCode = 1;
	}
	else
	{
		// TODO: code your application's behavior here.
	}

	return nRetCode;
}

为什么会有一堆编译错误，说那几个和网络相关的数据结构找不到呢?

我用的VC2005sp1. 谢谢！

你使用控制台程序写的吧，
控制台程序比较纠结
一个办法你换成 windows程序，
然后加上 #include "winsock2.h"
#include "iptypes.h"

如果你不换工程就纠结了
要注释掉 #include "windows.h"中的
#include "winsock.h"

[nalisaki]

GetMAC_mfc.cpp(10):不是说的是GetMAC_mfc.cpp文件中这几个数据类型找不到吗？在GetMAC_mfc.cpp文件中包含找不到的那些数据类型所在的头文件不行吗？
