Q: CDaoRecordset and AddNew

Environment: VC 4.0 and Win95

I am using CDaoRecordset Objects in connection to an ACCESS database.
When calling the AddNew funtion several times the debugger reports
a memory leak. The AddNew function allocates something like a cache
that is not freed. Is there a possibility to free that cache memory ?

thanks

Jochen

Can you reproduce this problem using a more current version of MFC?

In MFC 4.2, it looks like the cache is freed by CDaoRecordset::FreeCache().
In MFC 4.2, the pointers to the cache memory are public, so you could
just delete them directly if you're destructing the object yourself.
If you've written a CDaoRecordset-derived class, you can probably delete
them in your overridden destructor.

I'm afraid I've become some sort of speed freak.
