Answer 2

EnumWindows(@closeApp, integer(pchar('应用)));
function closeApp(wnd: HWND; cap:pchar)  : boolean ;stdcall;
var Caption: array[0..256] of Char;
begin
  if GetWindowText  (wnd, Caption, SizeOf(Caption)-1) <> 0 then
  begin
    if copy(strPas(Caption),1,length(strPas(cap)))=strPas(cap) then
       PostMessage(wnd,wm_close,0,0);
  end;
  Result :=True;
end;
