About WRL function argument of IVectorView

Question

Hi All，

I‘m developing a desktop application (MFC), but I need to use mobile hotspot feature.

Now i can start tethering by WRL API, but when I try get the tethering client info. I find the interface like below. It's so complex, I don't know how to make the right argument of IVectorView, I didn't find any useful info in the web. Can someone give me some hint?

Thank you very much

                INetworkOperatorTetheringClientManager : public IInspectable
                {
                public:
                    virtual HRESULT STDMETHODCALLTYPE GetTetheringClients(
                        __FIVectorView_1_Windows__CNetworking__CNetworkOperators__CNetworkOperatorTetheringClient** value
                        ) = 0;
                };

typedef IVectorView<ABI::Windows::Networking::NetworkOperators::NetworkOperatorTetheringClient*> __FIVectorView_1_Windows__CNetworking__CNetworkOperators__CNetworkOperatorTetheringClient_t;
#define __FIVectorView_1_Windows__CNetworking__CNetworkOperators__CNetworkOperatorTetheringClient ABI::Windows::Foundation::Collections::__FIVectorView_1_Windows__CNetworking__CNetworkOperators__CNetworkOperatorTetheringClient_t

Hi zheng cheng,

Thank you for posting in the Microsoft Community Forums.

ComPtr<IVectorView<NetworkConnectionProfile^>> profilesView;

// Assuming you've got the profilesView here somehow

UINT32 size = 0;

profilesView->get_Size(&size);

for (UINT32 i = 0; i < size; ++i)

{

ComPtr<NetworkConnectionProfile> profile;  

HRESULT hr = profilesView->GetAt(i, &profile);  

if (SUCCEEDED(hr))  

{  

    // Now you can use the profile, e.g. get its name  

    hstring profileName;  

    hr = profile->GetProfileName(profileName.GetAddressOf());  

    if (SUCCEEDED(hr))  

    {  

        wprintf(L “Profile Name: %s\n”, static_cast<const wchar_t*>(profileName.Get()));  

    }  

}  

}

Best regards
