If you are using DAO, it's not good idea. DAO don't support multiread/multiwrite actions.<br />
If you use DAO, you have to create a critical section to regulate the thread access to database.<br />
You can use ADO. It support multiread/multiwrite actions.<br />

I hop that you resolve your problem.<br />

My question was about MFC’s ODBC database classe(CDatabase,CRecordse<wbr />t,..)<br />
and not DAO classes(CDaoDatabase , CDaoRecordest,...).
</div>


<div>
MFC's ODBC classes are thread-safe<br />
You can use CDatabase and Crecordset classes in any app threads without worrying about simultaneous access.<br />

I want to use ODBC in a multithreaded application.Should I worry about simultanios access to record or ODBC itself manages it (by some sort of locking)? In other words should I use critical sections , etc when updating the database or executing a query ?

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
