This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So show us the code you are using, explain what is happening, and don't try to type as little as possible!

AfxDaoTerm is not closing the database. Quite the contrary it requires that all MFC DAO objects has been destroyed before calling it. Therefore you must not use instances of DAO objects but allocate them using new and delete them before calling AfxDaoTerm:

C++

CDaoDatabase *pDb = NULL;

// In InitInstance for global objects or function entry for local objects
pDb = new CDaoDatabase;

// Usage
pDb->Open();
// ...

// In ExitInstance for global objects or function exit for local objects
if (pDb)
{
    if (pDb->IsOpen())
        pDb->Close();
    delete pDb;
}

// ExitInstance
AfxDaoTerm();
