The previos version

[Vittorio]

The attaching to the ROT-Registered graph stopped working as well. What is the latest fully functional version?

[Dee Mon]

Since 1.4.0 it runs with administrator privileges. Two GEPs see each other's graphs in the ROT.
I guess if you run your app with elevated rights, you'll see its graph too.

[Vittorio]

This was the first thing I tried. Unfortunately not. I'm using Vista SP!, what about another two GEPs? And could you reproduce the crash?

[Dee Mon]

What do you mean by "another two GEPs"?
I was telling that if you run two copies of GEP, they see each other's graphs.

As for the crash after removing a camera, not yet, 'cause the only camera we currently have here is not removable.

[Vittorio]

Got it. Mea Culpa. Do you do anything differently under Vista to register the Graph in the ROT? What flags do you use? The code which worked just fine under all versions up to latest XP and registers the graph in the ROT has stopped working under the Vista. All system calls including Could you share just the raw idea? This is what works until Vista:

HRESULT AddGraphToRot(IUnknown *pUnkGraph, DWORD *pdwRegister)
{
    IMoniker * pMoniker;
    IRunningObjectTable *pROT;
    WCHAR wsz[128];
    HRESULT hr;

    if (!pUnkGraph || !pdwRegister)
        return E_POINTER;

    if (FAILED(GetRunningObjectTable(0, &pROT)))
        return E_FAIL;

    hr = StringCchPrintfW(wsz, NUMELMS(wsz), L"ActiGui %08x pid %08x\0", (DWORD_PTR)pUnkGraph,
              GetCurrentProcessId());

    hr = CreateItemMoniker(L"!", wsz, &pMoniker);
    if (SUCCEEDED(hr))
    {
        hr = pROT->Register(ROTFLAGS_REGISTRATIONKEEPSALIVE, pUnkGraph,
                            pMoniker, pdwRegister);
        pMoniker->Release();
    }

    pROT->Release();
    return hr;
}

Ah, Vista!
In Vista MS moved ROT-related functionality from quartz.dll to proppage.dll, so you need to locate and register (using regsvr32) proppage.dll to be able to work with ROT.

A quote from the internets:

In order ... to work on Windows Vista, you actually need to have the version of GraphEdit from the Windows SDK for Windows Vista and register the proppage.dll that comes with it. If you have the older version of GraphEdit from the previous version of the Windows SDK, it still won't work. It has to be the one from the Windows SDK for Vista. The reason for this is that Microsoft (in their infinite wisdom) removed almost all the proxy/stub pairs from Quartz.dll in Vista and moved them all into the proppage.dll file. Without the proxy/stub pairs registered, Windows can't marshal proxies from one thread apartment to another.

[Vittorio]

I know this but I didn't load any dll explicitly ever before. Do you do it now?

[Dee Mon]

No, you just need it registered in the system.
