void CNTestDlg::GetNameAndIp(CStringArray& NameArray,CStringArray& IpArray)
{
NameArray.RemoveAll();
IpArray.RemoveAll();

struct hostent *host;
struct in_addr *ptr;

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 = 10240;
LPVOID Buffer = new char[10240];
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(_T("\\\\")) )
strFullName = strFullName.Right(strFullName.GetLength()-2);

gethostname(szHostName,strlen(szHostName));
USES_CONVERSION;
char *pchar = T2A(strFullName);
host = gethostbyname(pchar);

if(host == NULL) continue;
ptr = (struct in_addr *) host->h_addr_list[0];

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
CString strTemp;
strTemp.Format(_T("%d.%d.%d.%d"),a,b,c,d);
NameArray.Add(strFullName);
m_IpArray.Add(strTemp);
}
}
}
delete Buffer;
WNetCloseEnum( hEnum );
}
WSACleanup();
}
