Question

How to disable maximize button in delphi program?

Answer 1

Oh! I found in object inspector "BorderIcons" Just set there biMaximize from true to false!

Answer 2

Here is another trick if you want to do it using code only.

procedure TForm1.FormCreate(Sender: TObject);
var
  l: DWORD;
begin

  // hide minimize and maximise buttons
  l := GetWindowLong(Self.Handle, GWL_STYLE);
  l := l and not(WS_MINIMIZEBOX);
  l := l and not(WS_MAXIMIZEBOX);
  l := SetWindowLong(Self.Handle, GWL_STYLE, l);

end;
