How do I removed warning dialog popups?

Hi,

I'm working on a bit of code that was made by some people a few years back and I've been trying to removed some warning dialog pop ups. The only way I could think of was to just comment the code involving them out but when I do that and then launch the program, them pop ups still occur. Any idea how I fix this?

Thanks.

Also, here is the code.

% --- Executes on button press in start_button.
function start_button_Callback(hObject, eventdata, handles)
target_pc_struct = get(handles.connect_button, 'UserData');
target_obj = target_pc_struct.target_obj;

try
    % Check if the target computer application is already running. If so, do nothing aside from
    % alerting the user.
    task_flag = 0;
    if (strcmp(target_obj.Status, 'running'))
        warndlg('The target application has already been started.', 'Application already running', 'modal');
    else
        % Get the default sample position parameters and reset (initialize) them in the model.
        task_flag = 1;
        build_params = target_obj.getparam(target_obj.getparamid('Build-dependent physical parameters', 'Value'));
        model_params = getConfigurations('ECHTGAIN_MODEL_PARAMETERS');
        target_obj.setparam(target_obj.getparamid('x_pos', 'Gain'), 0);
        target_obj.setparam(target_obj.getparamid('y_pos', 'Gain'), 0);
        target_obj.setparam(target_obj.getparamid('z_pos', 'Gain'), build_params(3)/2);
        target_obj.setparam(target_obj.getparamid('Time Const 1', 'Gain'), 1/model_params.horizontal_time_constant);
        target_obj.setparam(target_obj.getparamid('Time Const 2', 'Gain'), 1/model_params.vertical_time_constant);
        target_obj.setparam(target_obj.getparamid('frequency', 'Gain'), model_params.default_osc_frequency);
        target_obj.setparam(target_obj.getparamid('amplitude', 'Gain'), 0);

          % Start the target application on the target computer and collect the start timestamp.
           task_flag = 2;
           target_obj.start;
           time_stamp = now;
            warndlg('The application was successfully started on the target computer.', 'Application started', 'modal');

          % Store the timestamp on the target computer.
          task_flag = 3;
          target_obj.setparam(target_obj.getparamid('Initial timestamp', 'Value'), time_stamp);

          % Get the sampling period of the real-time application. Display the initial timestamp and
          % the sampling period. Clear the display boxes for stop timestamp, timestamp difference,
          % total execution time, and number of samples computed.
          tau = build_params(4);
          set(handles.start_timestamp, {'String', 'UserData'}, {getDateString(time_stamp, getNumberOfDecimalDigits(tau)), time_stamp});
          set(handles.sampling_period, 'String', tau);
          set([handles.stop_timestamp, handles.timestamp_difference, handles.execution_time, handles.number_of_samples], 'String', '');
      end
  catch err
      if (task_flag == 0 || task_flag == 2)
          msg = 'Could not start the application because an error occurred while attempting to communicate with the target computer.';
      elseif (task_flag == 1)
          msg = 'Could not initialize the sample position parameters because an error occurred while attempting to communicate with the target computer. The application will not be started.';
      elseif (task_flag == 3)
          msg = 'Could not store the starting timestamp on the target computer because an error occurred while attempting to communicate with it.';
      end
      beep;
      errordlg(sprintf('%s\n - Error identifier: %s\n - Error message: %s', msg, err.identifier, err.message), 'Communication error', 'modal');
  end

Just put a % in front of every call to warndlg(). If you still get them, then you missed some.

I've tried this and the popups still occur.

That's impossible. Just step though your code line by line until you find the line without the % that is causing the popup to occur.

Use find and replace and you can't possibly miss any... :)

Ctrl+F Find: warndlg Replace: %warndlg

There are also plenty of other kinds of dialog boxes that could be coming up. These might include the functions: dialog, errordlg, helpdlg, msgbox, questdlg, etc.

Search for the text being displayed in the box. It will be in the code somewhere if it was homemade.
