the name of my gui is g1.m associated with gi.fig
in command window:
>> h=g1
h =
173.0012
>> handles = guihandles(h)
handles =
figure1: 173.0012
waitbarr: 182.0012
exitt: 181.0012
pushbutton28: 180.0012
text24: 179.0012
push_opendatafile: 178.0012
text23: 177.0012
run_examine_N: 176.0012
panel_Nvalues: 15.0013
optimization: 11.0013
axes1: 6.0013
panel1: 3.0013
begin: 0.0013
run1: 174.0012
text18: 175.0012
editN: 17.0013
popup_Nvalues: 16.0013
help1: 14.0013
no: 13.0013
yes: 12.0013
reload: 5.0013
import: 4.0013
single: 2.0013
monte_carlo: 1.0013
doesnt this mean that the handle of my waitbar is 182.0012?
then why I get this response:
>> get(182.0012)
Error using handle.handle/get
Invalid or deleted object.

The handle is handles.panel1. You use that instead of the actual number. For what it's worth, here is the progress bar code I use:
%--------------------------------------------------------------------
% Displays a progress bar on the figure at the specified location.
% percentageDone should be a number between 0 and 1.
function handleToProgressBar = DisplayProgressBar(varargin)
%DisplayProgressBar: A progress bar that can be embedded in a GUI figure.
% Syntax and sample calling:
% progressBarPosition = [.007 .46 .38 .027]; % Position of progress bar in normalized units.
% handleToProgressBar = DisplayProgressBar(progressBarPosition);
% for k = 1:100
% percentageDone = k / 100;
% DisplayProgressBar(handleToProgressBar, percentageDone)
% end
% % Delete the progress bar. Make it disappear.
% delete(handleToProgressBar);

try
if ishandle(varargin{2})
% Progress Bar axes exist already. Just need to set the value.
handleToProgressBar = varargin{2};
%msgboxw('Progress bar already exists.');
value = varargin{3}; % Percent done, in the range 0-1.
numberOfImagesAlreadySnapped = int32(varargin{4});
grandTotalOfImages = int32(varargin{5});
p = get(handleToProgressBar, 'Child');
x = get(p, 'XData');
x(3:4) = value;
set(p, 'XData',x);
caption = sprintf('%d of %d Images = %.2f%%Done', numberOfImagesAlreadySnapped, grandTotalOfImages, value*100);
title(handleToProgressBar, []);
title(handleToProgressBar, caption);
return;
else
% Progress Bar axes doesn't yet exist. Need to create one.
% First argument is the size (not a handle).
%msgboxw('Progress bar does not exist yet. First argument is the location and size (not a handle).');
h = varargin{1}; % Get the handles structure.
progressBarPosition = varargin{2};
% Make sure we're on this figure, not the calibration figure like we are if we launch this from calibrate().
figure(h.figMainWindow);
drawnow;
if length(progressBarPosition) < 4
%msgboxw('Problem: length(progressBarPosition) = %d.', length(progressBarPosition));
% Should not happen. If it does, set up default.
progressBarPosition = [.007 .46 .38 .027];
end
backgroundColor = [236 0 140] / 255; % Fuschia, magenta.
foregroundColor = [0 128 0] / 255; % Dark Green
handleToProgressBar = axes('Units', 'normalized',...
'Position',progressBarPosition,...
'XLim',[0 1], 'YLim',[0 1],...
'XTick',[], 'YTick',[],...
'Color', backgroundColor,...
'XColor', backgroundColor, 'YColor', backgroundColor);
patch([0 0 0 0], [0 1 1 0], foregroundColor,...
'Parent', handleToProgressBar,...
'EdgeColor', 'none',...
'EraseMode', 'none');
% set(h, 'units', 'normalized');
% Set up a title for it.
title(handleToProgressBar, []);
title(handleToProgressBar, '0% Done');
end
catch ME
message = sprintf('Error in DisplayProgressBar():\n%s', ME.message);
WarnUser(message);
end
return; % from DisplayProgressBar()

handles.panel1
I would imagine since it doesn't look like you changed its tag. I don't know anything about that waitbar submission though as I use a different one that is in its own figure rather than embedded.
