RE: database access from VC++

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Charles

Thank you so much for your suggestions. It did help. Well, I've already
installed .NET framework on my computer and using SQL server 2005 database.
It seems that ADO.net would be the best option. I checked the site
Data Access Using ADO.NET in C++
http://msdn2.microsoft.com/en-us/library/9ctka9db(VS.80).aspx

It shows how to access data (creating/modifying tables) using ADO.net
DataTable object. But my database already exist in SQL server 2005. I need to
access SQL server 2005 database from VC++ interface.

Is there any difference in native and unmanaged code?

Hi Manjree,
I think that anyone of the three ways is OK. This depends on your
requiremnets. If you do not want to install .NET framework, you can use MFC
classes like CDatabase, CRecordset, OLE DB templates like CCommand and ADO.
For ADO.NET, you can interact with your ADO.NET database from native code,
however that requires your compiling your application with /clr switch.

For more information, you may refer to:

If your SQL Server is 2005, I recommend that you use ADO.NET or OLE DB
templates. ADO programming seems a bit more complex than other methods.

Hope this helps. If you have any other questions or concerns, please feel
free to let me know. It is my pleasure to be of assistance.
