I'm new in Direct Show

Question

I tried DirectShow programming with MFC using VisualStudio Proffesional 2013.
I had many experiences of programming with MFC and Visual C++ 6.0 and older.
Now, I have a problem in line 27 of following source code.
The m_pGraphBuilder->QueryInterface() returns "0x00773108<No Information. Cannot load Symbols of quartz.dll>".
I don't understand at all of this message.
Can somebody help me?
01: CMrlView::CMrlView()
02: : CFormView(CMrlView::IDD)
03: {
04: // TODO: 構築コードをここに追加します。
05: m_pGraphBuilder = NULL;
06: m_pMediaControl = NULL;
07: CoInitialize(NULL);
08: }
09:
10: CMrlView::~CMrlView()
11: {
12: CoUninitialize();
13: if (m_pMediaControl != NULL) { m_pMediaControl->Release(); }
14: if (m_pGraphBuilder != NULL) { m_pGraphBuilder->Release(); }
15: }

23: if (m_pMediaControl != NULL) { m_pMediaControl->Release(); }
24: if (m_pGraphBuilder != NULL) { m_pGraphBuilder->Release(); }
25: if (CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void **)&m_pGraphBuilder) == S_OK)
26: {
27: if (m_pGraphBuilder->QueryInterface(IID_IMediaControl, (void **)m_pMediaControl) == S_OK)
28: {
29: if (m_pGraphBuilder->RenderFile(L"C:\\Users\\naoki\\Videos\\g.mpeg", NULL) == S_OK)

For COM, you should not do "== S_OK". Instead you use the SUCCEEDED (or FAILED) macro.
Try:
HRESULT hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void **)&m_pGraphBuilder);
if (SUCCEEED(hr))
hr = m_pGraphBuilder->QueryInterface(IID_IMediaControl, (void **)m_pMediaControl);
if (SUCCEEDED(hr))
hr = m_pGraphBuilder->RenderFile(L"C:\\Users\\naoki\\Videos\\g.mpeg", NULL);
if (SUCCEEDED(hr))
m_pMediaControl->Run();
What exactly is the hr value from line 27? Your pasted message makes it look like it's an address, not an HRESULT.
BTW, you should enable the Microsoft Symbol Server for your development system. See
