Alternatives to DLL?

I was wondering is there any way that I can have a main form compiled into a EXE and EACH SECONDARY FORM COMPILED INDIVIDUALLY and then dynamically load in these other secondary forms in runtime ( DLL concept)

Why not?

(* The DLL unit *)

library MyLib;

type

  TMyDLLForm = class(TForm)

  ...

  end;

{$IF dynamically creation}

function CreateForm: TForm; {$IFDEF WIN32} stdcall;{ENDIF} export;

begin

  Result := TMyDLLForm.Create(Nil);

  Result.OnClose := @FreeForm;

end;

{$ELSE}

var

  MyDllForm: TForm;

function CreateForm: TForm; {$IFDEF WIN32} stdcall;{ENDIF} export;

begin

  Result := MyDLLForm;

end;

{$ENDIF}

exports

  CreateForm;

end.

(****************)

(* The Main Form in exe module. Calling the MyDLLForm *)

function CreateForm: TForm; {$IFDEF WIN32} stdcall;{ENDIF} external

'MyLib';

procedure TMyMainExeForm.OnOpenDllFormBtnClick(Sender: TObject);

var

  form: TForm;

begin

  form := CreateForm;

  form.owner := self;

  form.parent := self;

end;
