C++ (Cpp) ComPtr::GetAppWindowProvider Examples

Example #1

File: TriColorControlProvider.cpp Project: dbremner/old-Windows8-samples

IFACEMETHODIMP CTriColorControlProvider::Navigate(_In_ NavigateDirection direction, _Outptr_result_maybenull_ IRawElementProviderFragment ** retVal)
{
    *retVal = nullptr;
    ComPtr<IInspectable> spFragment;
    HRESULT hr = CheckDisconnected();

        {

    }

    // For the other directions (next, previous) the default of nullptr is correct
    return hr;
