Error in ==> test_lbox2>pushbutton1_Callback at 192 Adup=test_eucled(filename); Error in ==> gui_mainfcn at 96 feval(varargin{:}); Error in ==> test_lbox2 at 43 gui_mainfcn(gui_State, varargin{:}); Error in ==> guidemfile>@(hObject,eventdata)test_lbox2('pushbutton1_Callback',hObject,eventdata,guidata(hObject)) ???

You probably forgot to assign anything to it. hey image analyst!! u were rite....d filename comprises d name of d file alog wid its extension eg: ELEPHANT.JPG so i need to also pass d path of d image...which is contained in a variable called pwd eg: D:\Image Processing so now how do i pass d variable "filename" and "pwd" to d file test_eucled.m?? pls can u write d statement along wid d syntax....as in what statement will cum in d GUI and wat will cum in d file test_eucled.m??? i tried doin d follow bt it din workout... Adup=test_eucled(pwd,filename); %in d GUI function haar=test_lbox2(pwd,filename) fn=strcat(pwd,int2str('\'),filename); i included "\" bcoz pwd comprises of only d:\foldername so i need to put "\" after foldername and then d filename... thanx image analyst fr helping me out!!

You can use uigetfile() if you want to browse for a file [baseFileName, folder] = uigetfile({'*.*'}, 'Select file'); if baseFileName ~= 0 fullFileName = fullfile(folder, baseFileName); end or just type in the filename like this: fullFileName = 'c:\images\myimageFile.jpg'; then call your function: Adup=test_eucled(fullFileName);

By the way, you might want to use standard English. It really helps the non-English speaking users, and me as well - it takes about 10 times as long to read your message when you use cryptic non-words like: d cum wat wid bt dn pls din u rite alog, etc. Why not make it easy for us to read your requests?

hiii image analyst!! i have created a simple GUI which comprises of loading of images. Thank You for helping me out with that. My project supports only .JPG images. What i want is that when the user selects .BMP or .tiff images or any other image format except JPEG (by selecting All Files from open dialog box) then i want a MSGBOX to prompt informing the users to upload only .JPG images. How shall i do that??? i tried writing the follow code but it gives me error for selecting each and every image str='*.jpg'; if baseFileName == strcmp(str,baseFileName) global fullFileName if baseFileName ~= 0 fullFileName = fullfile(folder, baseFileName); end disp(fullFileName); setappdata(hMainGui, 'fileName', fullFileName); updateAxes else msgbox('please enter images of .jpg format', 'error'); end i just need help for showing the message box saying "please enter images of .jpg format"....Thank You again for helping me out with loading of image.....Now i just need to solve this problem regarding the Message Box...pls help...

How about: str =3D {'.jpg','.jpeg'}; [ext ext ext] =3D fileparts(baseFileName); if max(strcmp(str,ext)) global fullFileName if baseFileName ~=3D 0 fullFileName =3D fullfile(folder, baseFileName); end disp(fullFileName); setappdata(hMainGui, 'fileName', fullFileName); updateAxes else msgbox('please enter images of .jpg format', 'error'); end Does this work for you? -Nathan
