Somewhere you call Form.Show. Replace by Form.ShowModal.

if your form is not created automatically at runtime just do:

Procedure TForm1.Button1Click(Sender: TObject);
begin
 application.createform(TForm2, Form2);
 Form2.Showmodal;
end;

It is important to remember that modal forms can not be MDiChild and they will stay on top until you call the form's OnCloseEvent:

Action:=CaFree;


Hope it helps!

hmm,

i usual use something like this

begin
  with tFormWhichShouldBeShowedModal.create(self) do
  try
    showmodal;  
    //or if modalresult is needed
    //mres := showmodal;
    //
    //maybe transport some values from the form
    //for further process
    somevar := EditControlOnModalForm.text;
  finally
    release;
  end;
end;

Do not call CreateForm. Create is good enough.

Thanks all for the response.
I did indeed find the ShowModal, but was surprised I couldn't place this setting on the form properties itself.

As Robert was the first with th esolution, I'll reward him with the points, but I'm also gratefull for the other comments. Thanks guy's ;-)
