Maybe you can help me with this one then ...

Fire up D2005 (Architect Trial)

Select File | New Windows Forms Application

There is immediately a message in the "Messages" pane at the bottom of the
screen that I cannot read, *because it doesn't wrap around my screen*.
Rightclick/copying it here gives :

Could not find type 'WinForm.Container'. Please make sure that the assembly
that contains this type is referenced. If this type is a part of your
development project, make sure that the project has been successfully built.

Next, look for TADOConnection. Doesn't exist anywhere. Fire up Component |
Installed .NET compoonents ....

Eventually!!! A huge list of components appears, with check boxes down the
left I assume that, like VB, not all components are "enabled" by default.

Scroll to TADOConnection (General components), tick all TADOQuery etc and
close the dialog. A new tab appears in the Tool palette, "General".

Click on TADOConnection, drop on form, voila : Error

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)
   at Borland.Studio.Host.CreationManager.a(Type , Object[] , Type[] ,
Boolean )'.

I mean what am I doing wrong?
