   // ATTENTION: We did something a little unusual in

   // We want to be able to have a fixed pointer which other
   // parts of the snapin (e.g. the taskpad's Configure Logging command)
   // can use to get at the local file logging node.
   // So we have a member variable m_pLocalFileLoggingNode which
   // points to that node object.  However, we wanted to re-use
   // the features of CResultNodeWithChildrenList,
   // so we added this node to the list of children.
   // The children list will automatically take care of deleting
   // any nodes added to the list, so we must be careful that if the
   // list of children ever deletes these nodes,
   // we don't still try to use m_pLocalFileLoggingNode.
   // The practical solution is to never allow the children
   // list to try to repopulate itself, which in this case
   // means to not enable the MMC_VERB_REFRESH for the
   // CLoggingMethodsNode.  This is what we do.
