Formless application

I want to create an application that does not have a form.  However,  I want it to make use of the Timer component so that when a certain time is reached it displays a message to the user.  How can this be done ?

I would be grateful for any advice offered regarding this.

Try using this at the Forms OnCreate event:

Application.ShowMainForm:= False;

I tried this in Delphi 1 and unfortunately it does not work.

You are a most Generous guy mr. John Clarke, so I think I'll provide you with an example:

You'll just have to open Delphi, DoubleClick the OnCreate event of Form1, and then cut'n'paste the following lines into unit1:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ExtCtrls;

type
  TForm1 = class(TForm)
    Timer1: TTimer;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    Timer: TTimer;
    procedure OnTimer(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
  Timer:= TTimer.Create(Self);
  Timer.OnTimer:= OnTimer;
  Timer.Interval:= 10000;
  Timer.Enabled:= True;
  Application.ShowMainForm:= False;
end;

procedure TForm1.OnTimer(Sender: TObject);
begin
  If MessageDlg('Every ten seconds!, should I close now?',
                mtInformation,
                [mbYes,mbNo],
                0)=id_Yes
  Then Application.Terminate;
end;

end.

ok, this is a hack! Try it with the forms OnPaint event, or at least after the window is stopped showing (Not OnShow!)

procedure TForm1.FormPaint(Sender: TObject);
begin
  Hide;
end;
