hallo,ich nutze vs 2008

#include "Iphlpapi.h"

Mein Knopf:

// Get the buffer length required for IP_ADAPTER_INFO.
ULONG BufferLength = 0;
BYTE* pBuffer = 0;
if( ERROR_BUFFER_OVERFLOW == GetAdaptersInfo( 0, &BufferLength ))
{
    // Now the BufferLength contain the required buffer length.
    // Allocate necessary buffer.
    pBuffer = new BYTE[ BufferLength ];
}
else
{
    // Error occurred. handle it accordingly.
}

// Get the Adapter Information.
PIP_ADAPTER_INFO pAdapterInfo =
      reinterpret_cast<PIP_ADAPTER_INFO>(pBuffer);
GetAdaptersInfo( pAdapterInfo, &BufferLength );

// Iterate the network adapters and print their MAC address.
while( pAdapterInfo )
{
    // Assuming pAdapterInfo->AddressLength is 6.
    CString csMacAddress;
    csMacAddress.Format(_T("%02x:%02x:%02x:%02x:%02x:%02x"),
                        pAdapterInfo->Address[0],
                        pAdapterInfo->Address[1],
                        pAdapterInfo->Address[2],
                        pAdapterInfo->Address[3],
                        pAdapterInfo->Address[4],
                        pAdapterInfo->Address[5]);

    cout << "Adapter Name :" << pAdapterInfo->AdapterName << " "
         << "MAC :" << (LPCTSTR) csMacAddress << endl;

    // Get next adapter info.
    pAdapterInfo = pAdapterInfo->Next;
}

// deallocate the buffer.
delete[] pBuffer;

error LNK2019: unresolved external symbol _GetAdaptersInfo@8 referenced in function "public: void __thiscall CmacDlg::OnBnClickedCancel(void)" (?OnBnClickedCancel@CmacDlg@@QAEXXZ)

laut tut soll ich die lphlpapi.lib einbinden:

[/cpp]
#pragma comment(lib,"lphlpapi.lib")
[cpp]

LINK : fatal error LNK1104: cannot open file 'lphlpapi.lib'

die windows suche brachte auch keine lphlpapi.lib

Also wenn du statt einem kleinen "l" ein großes "I" am Anfang des Dateinamens der Lib schreibst, dann wird das der Linker auch finden.
