MATLAB Figure file trouble

The Capture button does capture images and saves it on a single folder. Whenever I'll push the Capture button It'll just keeps on capturing and saving images. What I want to do is whenever I will push Capture button, it will automatically update the image1.jpg textbox.

To make things clear:

Every hit to Capture button, the Edit textbox updates it's name to image1.jpg, 1 hit again to Capture, Textbox updates to image2.jpg etc.... please help me :(

The Capture button's code is

vid = videoinput('winvideo', 1);
set(vid, 'ReturnedColorSpace', 'RGB');
img = getsnapshot(vid);
imshow(img);

%this is where the image will be saved
counter  = 1;
baseDir  = 'C:\Users\Sony Vaio\Documents\Task\Appendix\images\';
baseName = 'image';
newName  = [baseDir baseName num2str(counter) '.jpg'];
while exist(newName,'file')
counter = counter + 1;
newName = [baseDir baseName num2str(counter) '.jpg'];
end    
imwrite(img, newName);

The Textbox's code is

function name_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end

Since I don't have your full code, I have made two assumptions:

1. I have changed the button's TAG to "button_capture"
2. Make sure your capture button code returns newName (if it is a separate function, if you do that in the callback, then don't worry).

Now find the callback when the button is pressed.

This will then be something like:

function button_capture_Callback(hObject, eventdata, handles)
% Run the capture button code
[newName] = capture_button_code(varargin);
% hObject is the calling object, ie; our button, we now update it's string
set(hObject,'String',newName)

After you set() the hObject string property, add a call to

drawnow()

i already figured the answer

tboxName = [baseName num2str(counter) '.jpg']; set(handles.name,'String',tboxName);

Thank you :)
