Problem with preference_page_instance 2010-10-30 15:39:13 Hi,I'm trying to upgrade my (very old) input plugin to the new SDK. It was originally written against 0.8.3.It compiled cleanly, and playback is working. However the configuration page did not support apply/reset, so I wanted to upgrade it.I updated my v2 prefpage to v3, derived a class from preference_page_instance.However, my preference page is a very very simple non-WTL/ATL/MFC dialog, so the WTL helpers are not appropriate (they don't even compile since I don't have WTL installed).This leaves me in a situation where my plugin does not compile, because preference_page_instance does not implement service_release() or service_add_ref(). This seems to be contrary to the SDK readme, which says that those are defined by the services and should NOT be overridden by implementations.Is it safe for me to implement those 2 methods as no-ops? Do I have to use them alongside or instead of using a destructor? Or am I _required_ to switch to using WTL for my preference page?
