The user will insert a data into the table. If the user suddenly inserts the wrong data, the table will be 'NaN'. My question is how I want to make the table does not display 'NaN' on the table but I want an error message appear. I have this coding: function Mytable1_CreateFcn(hObject, eventdata, handles) if isnan(Mytable1) set(hObject, 'Data', 0); errordlg('Input must be a number','Error'); end handles.Mytable2 = hObject; guidata(hObject,handles); But there is an error with this code. Is this coding are correct to answer my question? 0 Comments Show all comments Tags uitableguicode Products No products are associated with this question.

Some of the values the user can enter in editboxes are essential for the calculation that runs once the pushbutton is presses whereas others are not essential. However, I wanna create an error message that pops up when the user forgets to enter a value in the essential editboxes. I've https://www.mathworks.com/matlabcentral/newsreader/view_thread/302474 tried the following: value_edit1 = get(handles.edit_1,'UserData'); if value_edit1 == []; error('myApp:argChk', 'Entry required') end Since I am posting this here...it didn't work, which means no error message poped up when I left editbox1 blank. I also tried a few other things that didn't work either. I am also not sure what 'myApp:argChk' does and if I need to amend that fo my script (just got that from the matlab help section). Does anyone has some good suggestion how to get that to work? Many thanks, Rob Subject: How to create an error message for a GUI?

'Wrong amount of numbers!','warn') end end It gives a warning if the input wasn't exactly 10 numbers. So I guess you could change the if statement. Hopes this helps, Stefan Subject: How to create an error message for a GUI? From:

For example, if I have a simple GUIDE-generated GUI which runs code matlab gui error when a pushbutton is pressed, I know that I can use 'edit' text boxes to put in mathematical values ( the 'input boxes').If I was to put a word instead of a number into the input boxes, I know that there will be an error displayed on the MATLAB command window-however, is there a line of code which would allow me to display this message (or another message) in the input boxes, if the pushbutton were to be pressed?Any suggestion would be most helpful!-Nathan. 0 Comments Show all comments Tags matlab gui error messages display guide Products No products are associated with this question.

Check the documentation for these functions in your version of MATLAB as they might have been changed.%% try a=1/'abc'; catch ErrorMessage=lasterr; disp(ErrorMessage); end 0 Comments Show all comments Jan Simon (view profile) 57 questions 6,892 answe
