Next use a listbox command

if(get(hObject, 'Value') == get(hObject, 'Max'))
filelocation = get(handles.MAT_file, 'string');
%evaluate the sting as if it were a command. See notes on 
%apostrophies for this one.
 loadfile =['load ''' filelocation ''''];
 evalin('base',loadfile);
 eval(['varlist = who(''-file'' , ''' filelocation ''');']);
listofvars = [];
for menuFillItr = 1:length(varlist)
    listofvars = [listofvars varlist(menuFillItr)];
end
set(handles.listbox1,'String', listofvars);   
end

This is just a snippet from some code I wrote a while ago

MATLAB: Passing the listbox name to a function

You could pass handles.listbox2 (or as appropriate) to the function, which could then set() against the variable that holds that.

Or you could pass a string to the function, such as in the variable BoxName . Then you could

set( handles.(BoxName), ...)

MATLAB: Load folder’s images names to a Matlab listbox

You will get that error message if you had one folder and had, say, the 10'th item in the listbox selected. Then if you went to another folder and called LoadImageList() and that folder only had, say, 5 images. The listbox would still have a "value" property of 10 but there are only 5 items there. It can't select the 10th item, so it throws that warning message.

What you need to do is to add something like this after the for loop

if length(ListOfImageNames) >= 1
    set(handles.lstImageList, 'value', 1); % Select first item in listbox.
else
    set(handles.lstImageList, 'value', []); % Deselect all items.
end
