the problem of callback function creating a control by uicontrol function

if true
  % --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
global aryData
scrsz = get(0,'ScreenSize')  %获取显示器屏幕尺寸 
f_size= [scrsz(3)/15  0.2*scrsz(4)  0.6*scrsz(3)  0.7*scrsz(4)]
hf=figure('Name','图1','Position',f_size);  
set(hf,'NumberTitle','off') %隐藏数字标题即左上角的“Figure1,2..” 
set(hf,'NumberTitle','on') %显示数字标题 
set(hf,'Menubar','No')  %隐藏菜单栏 
set(hf,'Menubar','Figure')%显示菜单栏 

hb = uicontrol(hf, 'style', 'pushbutton', ...
    'units', 'normalized', ...
    'position', [0.75,0.8,0.2,0.1], ...
    'string', '对比',...
     'Callback', @pbCompare);
 %%%%-----------------------------------------
function pbCompare
global aryData
global totalTimes
msgbox('sucess')
disp 'sucess'
%%------------------------------------
end

pbCompare callback function cannot be performed. why? think you very muchu. email:[e-mail]

Callbacks must accept at least two arguments. They can ignore them but they must accept them. You can use varargin for this purpose.
