Many examples in the "getting started" section of the online
documentation under "programming m-files" (or similar title, that's
otomh not looking at index/toc).

While not highly recommended in general, look at the documentation for
GLOBAL as well.

I think u did not catch my problem. It is..

(I have 2 GUI: no. 1, the user will execute search (sql) and will get the user ID. Then when the user click the update button, another gui should open and at the same time shows that ID gotten in the first one).

I've never written a ML GUI (and can promise that I never will :) ) so
what's the way to do something there I don't know.

Sounds like GLOBAL may be the answer; others may have better ways to
design it, I don't know.

assuming the "update" button callback kicks off the 2nd GUI, why not passing a parameter via the function interface ?
Global and persistent variables usually require careful management, to prevent undesirable side effects.

Riccardo, how can I pass the parameter

function btnExecute_Callback(hObject, eventdata, handles)
value = get(handles.id, 'string');


value should be shown in 2nd gui after clicking this button. Plz clarify more!

The example answer to question #21 (and others) cover how to do these types of things.
