I want a delphi 2 app (with forms) to start with its main form hidden, and not show any icon in the taskbar of the task list. Also, I DO NOT want it to appear for a second and just then diapper, I want it to never appear in the first place.

More points may be granted if needed.

Did you try to put this in your projectfile
 Showwindow(application.handle,SW_HIDE)
just before application.run ?

That doesn't work! The project starts a taskbar icon, hides the taskbar icon and then shows the form normally!!
You mast add this to You'r MainForm OnCreate event.

procedure TForm1.FormCreate(Sender: TObject);
begin
  Left := -1000;  { You'r form is invisible on screen }
  showwindow( FindWindow (nil,@Application.Title[1]),sw_hide);  { application is invisible on task bar }
end;

Hi there alona,

Part one of your question is easy without dicking around and setting its location off screen.  Simple go to the DPR file and do the following:

PROGRAM HideForm;

USES
   Forms, OtherStuff;

{$R *.RES}

BEGIN
   Application.Initialize;
   Application.ShowMainForm := FALSE;  <-- Prevents form showing
   Application.CreateForm( TFormType, FormInstance );
   Application.Run;
END.

This is exactly what the ShowMainForm property was meant for.

Now part two of your question.  Do the following:

CONSTRUCTOR TForm1.Create( AOwner: TComponent );
BEGIN
   Inherited Create( AOwner );      {Create the object instance}

   ShowWindowAsync( (Owner AS TApplication).Handle, SW_HIDE );
END;

I hope this helps you out.
Cheers,
Ian C.
