Cursor position in the edit window using GUIDE

Hello, I am using KeyPressFunction for my edit text uicontrol to replace input characters with the string of "*". However, every time I set the string the cursor always goes at the beginning of the string. Is there any way to send it at the end? I know there is a "\r" special character, is there any special character that does the opposite? I have found some solutions which use actxcontrol, but I am trying to avoid that.

Here is the code snippet:

if true
  function edit_pass_KeyPressFcn(hObject, eventdata, handles)
  acceptable_characters=char([65:90 97:122]);
  if strfind(acceptable_characters,eventdata.Character)
      handles.password=[handles.password eventdata.Character];
      dummy_str=char(42*ones(1,length(handles.password)));
      set(handles.edit_pass,'String', dummy_str);
  end
  guidata(hObject,handles);
end

Thank you!
