 Situations may arise when it is necessary to refresh the underlying DAO collection objects. Normally, this should not be necessary, but it is a simple procedure if it is necessary. An example of when a collection might need to be refreshed is when operating in a multiuser environment with multiple users creating new tabledefs. In this case your tabledefs collection might become stale. To refresh the collection, you simply need to call the `Refresh` method of the particular collection object and check for errors:
 
 ```cpp
-DAO
-_CHECK(pMyDaoDatabase->m_pDAOTableDefs->Refresh());
+DAO_CHECK(pMyDaoDatabase->m_pDAOTableDefs->Refresh());
 ```
 
 Note that currently all DAO collection object interfaces are undocumented implementation details of the MFC DAO database classes.
