How to make string in edit_text1 from edit_text2 exp : In edit_text1 : 123456789 In edit_text2 : 123

[Jan]

The question is not clear. Do you want to get the first three characters, if so, what happens if the text1 has less than 3 characters? Do you want all characters of number < 4? Do you want to set text2 from the callback of text1 or by a timer or trigger by another event or ...?

Please post all necessary details.

Yeah, it wouldn't if your "tag" for the edit text control was edit_text1 like you said first.

% Get the string in the control called handles.edit_text1.
string1 = get(handles.edit_text1, 'String');

% Extract just a portion of it.
string2 = string1(1:3); % Or whatever you want to start and stop at.

% Send that string2 to the control called handles.edit_text2.
set(handles.edit_text2, 'String', string2);
drawnow; % If needed, like you're in an intensive loop.

Then show YOUR code because you did not run any of our code. You probably misspelled something, or are using different names for your controls and didn't modify our code to reflect that, or somehow otherwise changed things. Why don't you tell us the actual error message? Copy and paste all of the red error text that you see in the command window.

I used the wrong name of Text1 and Text2.

Now everything is okay. Thank you very much.
