How can I have application without a form? Ive tried coding the form to ShowWindow(Application.Handle, SW_HIDE) but I would prefer it to not have a form at all. Also can I still include components with my app as I would not be able to drop the component on the form? Thanks for any help.

Just the all the forms from the project, and do all the work in the Project source (the .DPR file).

You can still instatiate objects and component, but keep in mind that now you have to do it manually... and remember to free them.

Sure you can have an application without forms.

But then you will have to init every Component yourself.

If you can live with the fast that there are forms in the Exe just put this line in the projects source.

Application.ShowMainform := False;


Good Luck

Thanks again

exemple1 shows you a dpr file that displays a simple message when compiled and this requires no other code.

exemple 2 shows a dpr file, using a blanc form (unit1) to which it adds a label (I know you don't want a form, but I just wanted to demonstrate that you could create a form and a label at run-time, you can of course also do this for non-visual components, and then you won't need a form to display them, which I now did :-)


exemple1

program Project1;

uses
  Forms,dialogs;

{$R *.RES}

begin
  Application.Initialize;
  showmessage('This is a sample program');
  Application.Run;
end.


exemple2 :


program Project1;

uses
  Forms,dialogs,stdctrls,
  unit1 in 'unit1.pas' {form1};

{$R *.RES}
var
   form1 : tform1;
   label1 : tlabel;
begin
  Application.Initialize;
  showmessage('This is a sample program');
  form1 := tform1.create(application);
  label1 := tlabel.create(form1);
  label1.top := 10;
  label1.left := 10;
  label1.parent := form1;
  label1.caption := 'hello there';
  form1.show;
  showmessage('there you go');
  label1.free;
  form1.free;
  Application.Run;
end.

Tom,
