GUI Pushbutton, display user input?

Hi, I wrote the following code to pull out a user defined increment of photos and file those photos somewhere else (user defined) for DIC. For the pushbutton with the uigetdir prompt, I would like it to orginally say "Directory" or something, then once the user pushes the button the user navigates to their desired directory, then I would like the pushbutton to display what directory the user chose. How do I do this?

%In order to work the image files of interest must be in the current
%path/directory. They also must be in the .jpg format.

clear all;
clc;
f= figure;
selpath = 'Directory';

      uicontrol(f,'style', 'text','string', 'Enter Index','position', [65,355,100,20]);
      cinput = uicontrol(f,'style', 'edit','String','#','position', [100,325,30,30],'callback','c = get(cinput);C=c.String;I=str2num(C);');

      uicontrol(f,'style', 'text','string', 'Enter New Folder Name','position', [300,355,120,20]);
      binput = uicontrol(f,'style', 'edit','string', 'NewFolderName','position', [260,325,200,30],'callback','b = get(binput);B=b.String;');

      bdinput = uicontrol(f,'style', 'pushbutton','string', selpath,'position', [100,255,360,30], 'callback', 'selpath = uigetdir;');

      uicontrol(f,'style', 'pushbutton','string', 'Done','position', [460,200,40,30], 'callback', 'closereq');

      uiwait(f);

imagefiles = dir('*.jpg');%Find the jpg files
nfiles = length(imagefiles);%How many files are there

   if nfiles ==0 %If there are no .jpg files found output a message
       message1= sprintf('Please add your image folder to the current directory navigation bar.');
       msgbox(message1);
   end

for ii=1:nfiles
    currentfilename = imagefiles(ii).name;
    currentimage = imread(currentfilename);
    images{ii} = currentimage;
end

for jj = 1:I:nfiles
    bestdirectory = strcat(selpath,'\',B);%choosen by user
    mkdir(bestdirectory);
    j=['Image_S001_' num2str(jj-1,'%04d') '.jpg'];
    fulldestination = fullfile(bestdirectory,j);  %name file relative to that directory
    q=images{jj};
    imwrite(q, fulldestination);  %save the file there directory   
end

You should read up on guidata to read up on how to share data between callbacks of a GUI. A callback is not run when you create it, only when you click it.

A tip: use multiple lines if you define multiple Name,Value pairs, it really improves readability.

bdinput = uicontrol(f,...
    'style', 'pushbutton',...
    'string', 'Directory',...
    'position', [100,255,360,30],...
    'callback', 'selpath = uigetdir;[~,seldir]=fileparts(selpath);set(gcbo,''String'',seldir)');

Another option:

bdinput = uicontrol(f,...
    'style', 'pushbutton',...
    'string', 'Directory',...
    'position', [100,255,360,30],...
    'callback',@bdinput_callback);
%sometimes people use this:
%'callback',@(hObject,eventdata)bdinput_callback(hObject,eventdata,guidata(hObject))
%function bdinput_callback(hObject,eventdata,handles) %#ok<INUSD>

function bdinput_callback(hObject,eventdata) %#ok<INUSD>
handles=guidata(hObject);%load from shared guidata
selpath = uigetdir;
[~,seldir]=fileparts(selpath);
set(gcbo,'String',seldir)
handles.seldir=seldir;
guidata(hObject,handles)%save back to shared guidata
end

Thank you for pointing me in the right direction!
