长见识了！
我这个就是实现用密码登录，提示错误是
??? Error using ==> feval
Undefined function or method 'entersys_WindowButtonDownFcn' for input arguments of type 'struct'.
Error in ==> gui_mainfcn at 96
feval(varargin{:});
Error in ==> entersys at 44
gui_mainfcn(gui_State, varargin{:});
??? Error while evaluating figure WindowButtonDownFcn
另外跳出提示“用户名或密码错误”的窗口，而且密码没有用 * 显示出来。
读密码的代码是
handles.output = hObject;
[num txt raw]=xlsread('userinf.xls');
if ~iscellstr(raw)
for i=1:numel(raw)
n(i)=isnumeric(raw{i});
end
raw{n}=num2str(raw{n});
end
handles.user=raw(2:end,1)';
handles.code=raw(2:end,2)';
guidata(hObject, handles);
判断密码的是
c = get(hObject,'Currentcharacter');
if isstrprop(c,'graphic')
set(hObject, 'userdata', [get(hObject,'userdata') c])
set(handles.userpassword, 'string', [get(handles.userpassword,'string') '*'])
else
val = double(c);
if ~isempty(c)
switch val
case 13
%判断对错
user = get(handles.username,'string');
code = get(gcf, 'userdata');
users = handles.user;
codes = handles.code;
n = find(strcmp(users,{user}));
if length(n) && isequal(codes{n}, code)
h = msgbox('登陆成功！');
uiwait(h);
delete(gcf);
lightdesign;
else
errordlg('用户名或密码错误！', '错误提示');
set(handles.userpassword, 'string', '')
set(hObject, 'userdata', '')
end
case 8
str = get(hObject, 'userdata');
if ~isempty(str)
str(end) = [];
end
set(hObject,'userdata',str)
str2 = get(handles.userpassword,'string');
if ~isempty(str2)
str2(end) = [];
end
set(handles.userpassword,'string',str2)
end
end
end
