WP8 c++/Direct3D Launch Parameters (ProtocolActivatedEventArgs problem)

Question

Hi,
I need another help with WP8 app developing. I need to associate native c++/Direct3D app with file extension. It should not be problem - what I need is to read launch parameters to get file path. Problem is that ProtocolActivatedEventArgs
is not working, it is not contain any parameters. I even found some blog post and some guy has information that there is a mistake in MSDN documentation, but he don't have solution for this problem. (http://sanjeev.dwivedi.net/?p=369)
Can you please help me? How to solve that - open my app by clicking on *.gpx file.
Thanks

Hi Franklin,
thanks for your answer, but unfortunately it doesn't help - since I need that on C++/Direct3D project. As you can see in NavigationContext manual
there is no support for C++, especially "standard" C++ without component extension (C++/CX).
But I finally figure it out, with one small disadvantage - it needs to be targeted to WP8.1 universal app (for the future release of Windows 10 is actually an advantage :) ).
So here is the solution demo:
hr = m_view->add_Activated(Microsoft::WRL::Callback<ActivatedHandler>(
this, &Foo::OnActivated).Get(),
&m_activated_token);
HRESULT Foo::OnActivated(ICoreApplicationView* , IActivatedEventArgs* args)
// Here we can check if app is allready runnig (args->get_PreviousExecutionState) ...
ActivationKind kind;
if (!args || FAILED(args->get_Kind(&kind)))
return false;
ComPtr<IActivatedEventArgs> activatedArgs(args);
switch (kind)
case ActivationKind_Protocol:
ComPtr<IProtocolActivatedEventArgs> protocolArgs;
if (FAILED(activatedArgs.As(&protocolArgs)))
break;
ComPtr<ABI::Windows::Foundation::IUriRuntimeClass> startUri;
if (FAILED(protocolArgs->get_Uri(&startUri)))
break;
HSTRING uriHstring;
unsigned int length;
startUri->get_AbsoluteUri(&uriHstring);
// lets handle uriHstring in our way...
break;
case ActivationKind_File:
ComPtr<IFileActivatedEventArgs> fileActivatedArgs;
if (FAILED(activatedArgs.As(&fileActivatedArgs)))
break;
ComPtr<ABI::Windows::Foundation::Collections::IVectorView<ABI::Windows::Storage::IStorageItem*>> list;
HRESULT hr = fileActivatedArgs->get_Files(list.GetAddressOf());
ComPtr<ABI::Windows::Storage::IStorageItem> item;
if (FAILED(list->GetAt(0, item.GetAddressOf())))
break;
ComPtr<ABI::Windows::Storage::IStorageFile> file;
if (FAILED(item.As(&file)))
break;
// lets handle file in our way...
break;
return hr;
