I'd just like to double check that it *is* actually possible to marshal
IDispatch, right? I've got it using the marshallers in oaidl_p.c, but I
get fixmes from the RPC runtime like so:
fixme:ole:NdrConvert (pStubMsg == ^0x4d7a27a4, pFormat == ^0x53bc5f84):
fixme:ole:PointerUnmarshall unhandled ptr type=12
and so on. Eventually it crashes inside native code (i think) just after
returning from the proxy (well, i can see the last call to
NdrComplexArrayUnmarshall) and calling VariantInit.
Are those fixmes actually critical? The NdrConvert stub at least
suggests that it might be, and that it should throw an exception.
any insights welcome, thanks -mike
