To make a connection with ADO I must by creating it give the TComponent. But
the problem is that during the initialization part I don't have it.
How can I solve this problem?

Thank you!

Is this what you want?

unit MyUnit;

uses
  ADODB;

const
  Con: TADOConnection = nil;

implementation

initialization

  Con := TADOConnection.Create(nil);
  Con.ConnectionString := <Some connection string>;
  Con.Connected := True;

finalization

  FreeAndNil(Con);

end;

Don't see how you can your form hasn't been created yet and so none of
it's components. Personally I'd do this in the FormCreate or FormShow
events. Or better yet in a separate Login Form.

Put the component on a datamodule, remove the datamodule from the autocreate
list, create it in code in your units Initialization section, using an Owner
of Nil. Destroy it in the finalization section.

Be warned: any exceptions caused during this process or when opening the ADO
connection will likely *not* be trapped by the Application object, instead the
app will die a silent death with a run-time error.
