Dao DB
-
I'm using vc++ 6.0,MFC and the CDao classes to open up access databases because of the better performance over ODBC. But when I try to open an Access 2000 db, it can't do it. I assume this is because the Jet engine it is using is 3.x. Is there a way to set which jet engine is used??? Thanks

Please note that Microsoft really are trying to kill off DAO. If you want to future proof your application I would reccommend switching to ADO (there are some C++ wrapper classes for this).

This is true. Although, to be on rfraser's side, DAO *is* much more faster and efficient than ADO due to the fact thats its inherently closer to the native JET engine.
I have been using ADO, over DAO for a while now and know of its scalability. But the downside is that you lose the data access speed that DAO is so good at.
Switching to ADO, no matter what the speed depreciation, is the way forward. If I remember correctly, Microsoft has stopped support for the JET engine as of V2.7 of the ADO distribution files. This is to promote the MSDE engine; a localised, 'baby' version of the SQL Server database system.My advice is to start out on your db adventure with the CDAO* classes then quickly move on to ADO for real world, scalable applications.

Hi , just an question from a novice like me : how to use #import in c programme ? not c++ is there an directive like it for c ? it's for use ADO in a c program thank you Adel that which hesitates is lost. that which hesitates is lost.
