borland C++ builder 6 (closing windows)

I opened a form using this command:

Code:

---

Form2 = new TForm2(Application);
  Form2->ShowModal();
  delete Form2;

---

(its my about menu)... now how do i close it with a ok button? what do i put in the ok button code?

...button OKClick...
{
Close();
}

If your window is an MDIchild you must write in the OnClose option

Action=caFree();
