如何获得本机IP地址，请高手指点！谢谢！

[beijingshizi]

WNetOpenEnum函数使用的头文件是什么？

是winsock2.h吗？可是我使用的时候报错

[beijingshizi]

一位同仁给的例子，搞不定，请大家看看，谢了！
#include "winsock2.h" ??????

CString strTemp;
struct hostent *host;
struct in_addr *ptr; // 获取IP地址的结构
DWORD dwScope = RESOURCE_CONTEXT;
NETRESOURCE *NetResource = NULL;
HANDLE hEnum;
WNetOpenEnum( dwScope, NULL, NULL, NULL, &hEnum );
WSADATA wsaData;
WSAStartup(MAKEWORD(1,1),&wsaData);
if ( hEnum )
{
DWORD Count = 0xFFFFFFFF;
DWORD BufferSize = 2048;
LPVOID Buffer = new char[2048];
WNetEnumResource( hEnum, &Count, Buffer, &BufferSize );
NetResource = (NETRESOURCE*)Buffer;
char szHostName[200];
for ( unsigned int i = 0; i < BufferSize/sizeof(NETRESOURCE);
i++, NetResource++ )
{
if ( NetResource->dwUsage == RESOURCEUSAGE_CONTAINER &&
NetResource->dwType == RESOURCETYPE_ANY )
{
if ( NetResource->lpRemoteName )
{
CString strFullName = NetResource->lpRemoteName;
if ( 0 == strFullName.Left(2).Compare("\\\\") )
strFullName = strFullName.Right(strFullName.GetLength()-2);
gethostname( szHostName, strlen( szHostName ) );
host = gethostbyname(strFullName);
if(host == NULL) continue;
ptr = (struct in_addr *) host->h_addr_list[0];
// 211.40.35.76 分割成如下形式.
int a = ptr->S_un.S_un_b.s_b1; // 211
int b = ptr->S_un.S_un_b.s_b2; // 40
int c = ptr->S_un.S_un_b.s_b3; // 35
int d = ptr->S_un.S_un_b.s_b4; // 76
strTemp.Format("%s --> %d.%d.%d.%d",strFullName,a,b,c,d);
AfxMessageBox(strTemp);
}
}
}
delete Buffer;
WNetCloseEnum( hEnum );
}
WSACleanup();

为什么要这么麻烦?
注册表里有.

[beijingshizi]

那如何得到？

[SecretGarden]

Win2K和Win98不一样,先要判断PlatformVersion

[beijingshizi]

这个我知道，然后呢？
如果是VER_PLATFORM_WIN32_WINDOWS的话？在那儿找到？

[莫等闲]

// 记得先初始化SOCKET
char name[30];
ZeroMemory(name,sizeof(char)*30);
gethostname(name,30);
struct hostent *myhost;
myhost = gethostbyname(name);
char* myip = inet_ntoa(*((struct in_addr*)myhost->h_addr_list[0]));

gethostname
gethostbyname

[easydw]

WORD wVersionRequested;
WSADATA wsaData;
char name[255];
CString ip;
PHOSTENT hostinfo;
wVersionRequested = MAKEWORD( 2, 0 );
if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
{
if( gethostname ( name, sizeof(name)) == 0)
{
if((hostinfo = gethostbyname(name)) != NULL)
{
ip = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list);
}
}
WSACleanup( );
}

以上程序在win98、win2k下测试通过
注释：name为本机名称，ip为本机ip地址；

不用客气
好东西要大家分享嘛！

谢谢凡星老兄，不凡嘛～～^_^
