Hello, When I make A winform .NET project I dont have the ADO.Net components available, and if I go in the 'Installed .NET components and check the checkbox so they appear then when I try to put one on the form I get : 'La création d'une instance de 'Borland.Vcl.TADOConnection' a échoué, car 'System.MissingMethodException: Constructor on type Borland.Vcl.TADOConnection not found. at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at Borland.Studio.Host.CreationManager.a(Type , Object[] , Type[] , Boolean )'.' So Is it possible to use the ADO components under D2005 Pro in a Winform project ?

I think you're mixing up some things here - ADO and ADO.NET. ADO is a COM-based set of components, which is available in .NET, if you must use them, by COM Interop. You will need to add a reference in your project to the COM class library for ADO. I don't see any reason why you'd want to do this, except if you can't find a way to get at your data with ADO.NET You *DEFINITELY* have ADO.NET available in your Winforms project - again, if you want to use it. You should see the "Borland Data Provider" (BDP) components in your toolbox - if not, you can always add them manually. I would strongly recommend using ADO.NET over straight, COM-based ADO, for a number of reasons - ease of use and performance among the top reasons for this.

Yes I did mean ADO.NET, and the components do not work under my copy of Delphi 2005 with update 2. I guess I'll have to reinstall again.... But are they easyer or faster than the BDP components ? (for Firebird databases) and can one autogenerate the SQL for the insert/modify/delete... ?

But are they easyer or faster than the BDP components ? (for Firebird There is no BDP provider for Firebird. The InterBase driver might work with Firebird 1.5 (I have not tried it) but this is unlikely to be true with future releases of Firebird.

Yes, you can autogenerate the SQL at design time by clicking a button in the DataAdapter Configuration dialog or at runtime using the CommandBuilder object. -- Bill Todd (TeamB) Back to top Bill Todd Guest Posted: Wed Jul 13, 2005 2:51 pm    Post subject: Re: Delphi 2005 winforms : can one use ADO?

The InterBase driver works with Firebird 1.5 up to a point, I did a test program and I could read the database as long as the SQL was filled at runtime but could not do the 'Generate SQL' , I posted a message in the BDP newsgroup about that (you read it and gave me a question by the way). It seems you just awnserd my questions about the bdp, Sad that it does not fully support Firebird.
