go to next function in one callback?

ching l — Thu, 17 Jul 2008 10:19:02 -0400

In Gui, how do I command the callback function to go to the
next function?

For example, when I first press the button, it will go to this,

function answer_faster_Callback(hObject, eventdata, handles)
csvwrite('subject1.dat',[1;00;55]);

then when I press again, it will go to this,

csvwrite('subject2.dat',[3;5;6]);

Possible to do that?

Thanks.

yes, just save where you ere in the handles or a global
variable and do the next thing each time.

Yes,

function answer_faster_Callback(hObject, eventdata, handles)
  persistent fargs
  if isempty(fargs)
    fargs.args = {{'subject1.dat',[1;00;55]}, {'subject2', [3;5;6]}, ...
                  {'subject3.dat',[17;8;21]}, {'subject4', [255;0;255]};
    fargs.count = 1;
  end

  csvwrite(fargs.args{fargs.count,1}, fargs.args{fargs.count,2});
  fargs.count = fargs.count + 1;
  if fargs.count > length(fargs.args)
     set(hObject, 'Callback', '');
  end
end

I got some changes of this...not very sure how to work it out...

Is it possible to retain the previous value of the callback?
something like this, but I know this is not right. I want
the callback to store the previous count value and store in
current count value

handles.s {counter} = [(handles.id), (handles.randValue), 2]

handles.scount= 1
handles.scount= handles.scount +1 ;

handles.s= [handles{count}, handles{count-1};]

so let say handles.s {1} = [1, 2, 3];
           handles.s {2} = [4, 5, 6]; handles {1};
           handles.s {3} = [7, 8, 9]: handles {2};


so on and so forth...

This would set up network address, then to return to the kind of data transmission, is how the application of this Â» That this is the first to write themselves a callback function, and then set up the callback function to libcurl Curry, and then specify what kind of format to receive data, when libcurl to return to the data will set the callback function. Are as follows:
Callback function definitions:
size_t write_data (void * buffer, size_t size, size_t nmemb, void * userp);
Set up a callback function:
curl_easy_setopt (easyhandle, CURLOPT_WRITEFUNCTION, write_data);
Set up a callback function to receive the data format:
curl_easy_setopt (easyhandle, CURLOPT_WRITEDATA, & internal_struct);

Through the above settings, you can receive data to the callback function inside, then how is the kind libcurl command to start the download data or upload the data? Â» Below on the function curl_easy_perform, this function is to connect remote sites, began operating agreements related to the order, calling the examples are as follows:
success = curl_easy_perform (easyhandle);

Above through a series of calls, you can connect with the HTTP server and download the data and reached in the callback function. When finished using the library after this, do not forget to call functions curl_global_cleanup () to do the removal work.

Is it possible to retain the previous value of the

I want the callback to store the previous count value and
store in current count value

handles.scount= 1;
handles.scount= handles.scount+1;

handles.sc{handles.scount}= [handles.id,
(handles.randValue), 2]

handles.s = [handles.sc{handles.scount};
handles.sc{handles.scount-1}]

guidata(hObject, handles);

it still doesn't return the previous count value..any idea how?

Get rid of the semicolons so you can see what's happening. Look at the
all the values on each click, figure out what isn't changing the way you
want, fix it, and try again.

dreammissu, is that a reply to the previous discussion, or did you happen
to start a new discussion under an old title? If you were starting
a new discussion, then I could not make out what your question was?
