Convert Delphi 5 ADO App to Delphi 2007 ADO.NET
I have an appliction tha that is writen in Delphi 5 with ADOConnetion, ADOTable, and ADOQuery components.
I need to upgrade to Delphi 2007 and use ADO.NET.
I have the program building in with Delphi 2007. Is there anything I need to do to convert the ADO to ADO.NET?

Reasons for ...ADO not ADO.NET
I have to connect to a db using adodb (which i select from the references). I have to retrieve the car models from the database and bind them to a listbox. I am not sure how to proceed and I can't find any articles on ADO with .net and data binding.
Here is the code that i tried but it only retrieves the car model for the specified id. If I delete the id it doesn't work. Also it writes the car model in the listbox vertically such as:

...Type Mismatch error when sorting ADO tables [Edit]
I have an app with a form with two dbgrids setup as master/detail. I placed two TGroupboxes with two radiobuttons each. One of the sets of radiobuttons sorts the Projects(master) dbgrid and the other sorts the Comments(detail) dbgrid. Both sorts are on a date field in the underlaying ADO tables. When I run the app, sorting just one of the dbgrids works fine until I try to click on the other dbgrid or the associated radiobuttons at which time I get the "Type Mismatch" error popping up.
The ADO components are on a datamodule and are as follows:

Hi, I am trying to convert this code from ADO to ADO.NET
I am very new to ADO.NET and am a bit confused on how I would convert this.
Basically what I am trying to do is capture the name of the fields of a table to populate a dropdownlistbox. The table name will change every time the program is run. This is not a problem and I can code for that.
Here is what I have in ADO (I have tried the wizard but it did not change the code)

I am having ADO.NET course these days. I asked the instructor that developing online system like airline reservation system needs to a connected environment to lock/Unlock the table when u read/write to it Can that be acomplished using ado.net.
His answer was no
ADO.NET is only for disconnected environment and it will not work with online system and i still should use the old ADO. ADO.NET is not a replacment for ADO and both will continue in paralell.
IS his answer true that ADO.NET will not replace ADO and both will continue
