unresolved external symbol IID_IADs?

Question

I'm trying out the sample program below, but it won't link because of unresolved external symbol for both IID_IADs and IID_IADsContainer.

What library am I support to include to resolve that?

#include <windows.h>
#include <activeds.h>
#include <comdef.h>
#include <iostream>

#pragma comment(lib, "Activeds.lib")

int main() {
    HRESULT hr = CoInitialize(NULL);
    if (FAILED(hr)) {
        std::cout << "Failed to initialize COM library." << std::endl;
        return 1;
    }

    IADsContainer* pContainer = NULL;
    hr = ADsOpenObject(L"LDAP://DC=mydomain,DC=com", NULL, NULL, ADS_SECURE_AUTHENTICATION, IID_IADsContainer, (void**)&pContainer);
    if (FAILED(hr)) {
        std::cout << "Failed to bind to Active Directory." << std::endl;
        CoUninitialize();
        return 1;
    }

    IEnumVARIANT* pEnum = NULL;
    hr = ADsBuildEnumerator(pContainer, &pEnum);
    if (FAILED(hr)) {
        std::cout << "Failed to get enumerator." << std::endl;
        pContainer->Release();
        CoUninitialize();
        return 1;
    }

    VARIANT var;
    ULONG lFetch;
    IDispatch* pDispatch = NULL;
    IADs* pADs = NULL;
    BSTR bstrClass;

    while (S_OK == ADsEnumerateNext(pEnum, 1, &var, &lFetch)) {
        pDispatch = V_DISPATCH(&var);
        hr = pDispatch->QueryInterface(IID_IADs, (void**)&pADs);
        if (SUCCEEDED(hr)) {
            hr = pADs->get_Class(&bstrClass);
            if (SUCCEEDED(hr)) {
                if (_wcsicmp(bstrClass, L"computer") == 0) {
                    BSTR bstrName;
                    hr = pADs->get_Name(&bstrName);
                    if (SUCCEEDED(hr)) {
                        std::wcout << L"Computer: " << bstrName << std::endl;
                        SysFreeString(bstrName);
                    }
                }
                SysFreeString(bstrClass);
            }
            pADs->Release();
        }
        VariantClear(&var);
    }

    ADsFreeEnumerator(pEnum);
    pContainer->Release();
    CoUninitialize();
    return 0;
}

@RemyLebeau pointed out the correct solution, Setting Up the Microsoft Visual C++ 6.0 Development Environment.

1. Point to the include and library directory. Select Tools | Options. Click the Directory tab, and specify the path to the ADSI header files.
2. Include the Activeds.h file in your project.
3. Add the Activeds.lib and Adsiid.lib files to the linker input for your project.
