If I understand you correctly, you want to extract the text from a message box and copy it to a text box in your GUI.
Step 1: Copy the message box string.
mh = msgbox('Copy this text.'); %Create a message box
th = findall(mh, 'Type', 'Text'); %Get the handle to the text within the box
msgString = th.String{:}; %Copy the string
Step 2: put the string in your your text box
The handle to you text box in this example is h.text1.
h.text1.String = msgString;

thank you sir..
I get the out put from this code.
im=imread(fname);
imshow(im);
title('Test Image');
%% Fond out which Class it Belongs to
Ftest=FeatureStatistical(im);
%% Compare with Database
load db.mat
Ftrain=db(:,[1,2]);
ctrain=db(:,3);
for(i=1:size(Ftrain,1))
dist(i,:)=sum(abs(Ftrain(i,:)-Ftest));
end
Min=min(dist);
if(Min<3)
m=find(dist==Min,1);
det_class=ctrain(m);
msgbox(strcat('detected class',num2str(det_class)));
else
msgbox('Not Exist');
end
can I extract that value to a text box?

To use my method, you need the handles to your message box.
mh = msgbox(strcat('detected class',num2str(det_class)));
mh = msgbox('Not Exist');
Then follow my example.
