I'm trying to write a .net application that will connect to a VAX RDB database using an Oracle RDB ODBC driver.  The driver is not .net compliant.  I'm not sure which components I should be using.  When I try to drop a TADOConnection control on the form I get the following message:

Failed to create an instance of 'Borland.Vcl.TADOConnection' because '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)


Thanks for any and all help.

Alan

Where did you get the controls? This sounds like it is a Winforms
component which has a different constructor to a VCL component.

I got the TADOConnection in the General section of the tools.

Sorry to be such an idiot about this.  My real question I guess is what set of components should I be using that work in a winforms application but use the "old" ADO and not ADO.net.

thanks, Alan

You can't really. Why don't you want to use ADO.NET?
