MATLAB: Undefined function ‘timeoutDlg’ errors out

Hi,

In my code I have usage of timeoutDlg to pop up a box to take user input. It worked fine and suddenly it started complaining as follow, what could be wrong here?

*******************************************

Undefined function 'timeoutDlg' for input arguments of type 'function_handle'.
Error in Configs (line 10)
gRunName = timeoutDlg(@inputdlg, 60,'Name this NGFSSC run:','NGFSSC');
Error in Interface (line 9)
Run = Configs(LocalDirectory);

Neesha - I suspect the problem is that your timeoutDlg function is no longer within the MATLAB search path. Try typing the following in the Command Window

 which timoutDlg -all

The above will display the full path to the timeoutDlg…if it exists. If it doesn't, then look for the folder that contains the file and add it to the search path.

If you can't find the file (maybe it has been deleted), then try creating it again. (Presumably, you obtained this file from http://www.mathworks.com/matlabcentral/answers/96229-how-can-i-have-a-dialog-box-or-user-prompt-with-a-time-out-period.)

There might be better ways, but this does work:

 msg=['Number not found in array. Or you may have ',...
     'not entered a number. Program terminating.'];
 errordlg(msg, 'File Error');

MATLAB: How to have a dialog box or user prompt with a time-out period

Currently, there is no built-in command in MATLAB that includes a time-out period for the dialog/input prompt.

As a workaround, you can use the TIMER function to close the dialog at time-out. An example is provided below.

function varargout = timeoutDlg(dlg, delay, varargin)
% Dialog function with timeout property
% dlg is a handle to the dialog function to be called
% delay is the length of the delay in seconds
% other input arguments as required by the dialog
% EXAMPLE FUNCTION-CALL
% To display an input dialog box (REFER MATLAB HELP DOC) with a 
% timeout = 6 second say, the function call would be:
%
% [matrix_size_value, colormap_string] = timeoutdlg(@inputdlg, 6, ...
%                                {'Enter matrix size:','Enter colormap name:'}, ...
%                                'Input for peaks function', 1, {'20','hsv'})
% Setup a timer to close the dialog in a moment
f1 = findall(0, 'Type', 'figures');
t = timer('TimerFcn', {@closeit f1}, 'StartDelay', delay);
start(t);
% Call the dialog
retvals = dlg(varargin{:});
if numel(retvals) == nargout
      varargout = retvals(:);
else
      varargout = cell(1, nargout);
end
% Delete the timer
if strcmp(t.Running, 'on')
       stop(t);
end
delete(t);
function closeit(src, event, f1)
disp('Time out!');
f2 = findall(0, 'Type', 'figure');
fnew = setdiff(f2, f1);
if ishandle(fnew);
      close(fnew);
end
