The user will insert a data into the table. If the user
Matlab Try Catch
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.

You may also want to uiwait() around the errordlg() so that you force the user to acknowledge the error. Your present code pops up the error but the user can hide it

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 tried the following: value_edit1 = get(handles.edit_1,'UserData'); if https://www.mathworks.com/matlabcentral/newsreader/view_thread/302474 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: ImageAnalyst Date: 8 Feb, 2011 14:15:55 Message: 3 of 5 Reply to this messa
