Q:  How do I create a form with the equivelent of the visual basic 'FIXED DOUBLE' border with NO caption bar?

A:   Just override CreateParams thus:

  private
    { Private declarations }
    procedure CreateParams(VAR Params: TCreateParams); override;
  ...
procedure TForm1.CreateParams(VAR Params: TCreateParams);
begin
  Inherited Createparams(Params);
  WITH Params DO
    Style := (Style OR WS_POPUP OR WS_BORDER) AND NOT WS_DLGFRAME;
end;
