how to interrupt the exececution?

      clear;
      close;
        uicontrol('Style', 'pushbutton', 'String', 'Browse','Position', [20 20 50 20],...
              'Callback', '[filename,pathname] = uigetfile');

imagefiles = dir(pathname);
% Number of files found
nfiles = length(imagefiles);

Hi. I want to create a Browse button, point to the folder where my files (images)

are, get the folder path and use it for getting the number of he files;

but the program is running up to the end without 'pathname' set.

thanks
