C++ Builder 4 + ADO

Hi all,

I'm evaluating Diamond ADO components with C++ Builder. Everything
works fine as long as I use these components at design time. When I'm
creating a TAdoQuery object at run-time and free it's resources after
using it, I get a compiler error in the systobj.h header file:

[C++ Error] systobj.h(242): E2315 'Release' is not a member of
'Ado21::_Recordset', because the type is not yet defined

When I remove the delete statement for freeing the memory, everything
compiles fine. When I bring it in, the compiler appears. I can't
figure it out. Can anyone help me out?

Also I've looked at the Borland website in order to investigate if the
ADOExpress components can be used with C++ Builder 4. They are
claiming that it can't be done.

Has anyone has good expiriences with third party ADO components that
work with C++ Builder 4? I'm trying to migrate from BDE to ADO and
this for a large project. Do we need to upgrade to C++ Builder 5 or 6
in order to accomplish this?

I know these are a lot questions, but all advice would be highly
appreciated!

Thanks in advance
