NS_ERROR_FACTORY_NOT_REGISTERED error - Please help.

[Paul Rouleau]

Hi,

I'm in the early stages of embedding gecko in my own MFC test
application.

So far, I am only calling NS_InitEmbedding( nsnull, provider );   My
provider class is currently identical to winEmbedFileLocProvider.

I'm getting a curious failure inside NS_InitEmbedding.  Internally this
function calls:

nsCOMPtr<nsIObserver> mStartupNotifier =
do_CreateInstance(NS_APPSTARTUPNOTIFIER_CONTRACTID,
                                         &rv);
if(NS_FAILED(rv))
    return rv;


When I test the value of rv, it is not 0.

Digging deeper, it appears that
nsComponentManagerImpl::CreateInstanceByContractID is failing in a call
to FindFactory.   The error code from FindFactory is
NS_ERROR_FACTORY_NOT_REGISTERED.


I've looked through the source code for mfcEmbed and connot figure out
how the "factory" gets registered.    Am I going blind?


I could sure use some help here.

Thanks,
   Paul
