The difference is in what object owns the form. You can also specify nil as the owner, if you don't need the object to be owned by anything. > procedure TForm1.Button1Click(Sender: TObject); > Var > Form2: TForm2; > begin > Form2:= TForm2.Create(Self); > Form2.Show; > end; With that way, Form2 will get destroyed automatically when you free the owning instance of TForm1. > Here is the alternate method as I understand it: > > procedure TForm1.Button1Click(Sender: TObject); > Var > Form2: TForm2; > begin > Form2:= TForm2.Create(Self); > Form2.Show; > end; That way is the same. Did you mean this? Form2 := TForm2.Create(Application); With that way, Form2 will get destroyed when the application object gets destroyed. A component destroys all the components it owns before it destroys itself. -- Rob ------------------------ Yahoo!
