I don't have any BEGIN_OBJECT_MAP entries, but I think as of VC7, ATL
switched to using OBJECT_ENTRY_AUTO() macros instead. I'm using VS
2005, if that helps.

I do have an OBJECT_ENTRY_AUTO() macro at the bottom of my
wizard-generated IMyModule.h

OBJECT_ENTRY_AUTO(__uuidof(IMyModule), CIMyModule)

as well as a COM_MAP entry in my CIMyModule() class

    DECLARE_REGISTRY_RESOURCEID(IDR_IMYMODULE)

    BEGIN_COM_MAP(CIMyModule)
        COM_INTERFACE_ENTRY(IIMyModule)
        COM_INTERFACE_ENTRY2(IDispatch, IComponentRegistrar)
        COM_INTERFACE_ENTRY(IComponentRegistrar)
    END_COM_MAP()

I wasn't entirely correct before, though. The interface is being
properly put in to the registry, it's only that when I try to access
it, I get the REGDB_E_CLASSNOTREG error from:

{
    //...
    MyModuleLib::IIMyModulePtr pModule = NULL;
    HRESULT hr = pModule.CreateInstance(TEXT("MyModule.IMyModule"));
    //...
}

I have a COM DLL (created with the ATL COM wizard). It comes with the
function:

// DllRegisterServer - Adds entries to the system registry
STDAPI DllRegisterServer(void)
{
    // registers object, typelib and all interfaces in typelib
    HRESULT hr = _AtlModule.DllRegisterServer();
    return hr;
}

This function does get called when the object is registered, but none
of the interfaces I have defined get registered.
Do I need to put code in to manually register my objects? What does
that function register, then?

Thanks,

Have you checked, that each COM class is in the object map of your
server? Opening the .cpp file of the server, you should find something
like that:

BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_<your COM class>, <class name of implementation>)
END_OBJECT_MAP()
