Second Form and Thread

Good morning.

A modal form has not to be closed with "TForm.Close".

Zitat von Delphi Help:

To close a modal form, set its ModalResult property to a nonzero value.

As next here is the example of the same help topic. It explains, how to close the modal form in the right way.

Delphi-Quellcode:

			procedure TMyDialogBox.OKButtonClick(Sender: TObject);

begin

  ModalResult := mrOK;  // mrOK ...

end;

procedure TMyDialogBox.CancelButtonClick(Sender: TObject);

begin

  ModalResult := mrCancel;  // ... and mrCancel are nonzero values

end;

// This code brings up the modal dialog from Form1 when a button is clicked.  It causes a Beep if the OK button is clicked.

procedure TForm1.Button1Click(Sender: TObject);

begin

  if MyDialogBox1.ShowModal = mrOK then

    Beep;

end;

So you don't need to thread this modal form for that simple problem.
