Hello everybody,
is there a way to disable Ctrl+C when no edit text or similar has focus, to prevent it crashing a GUI?
Thanks

No, there is not. control-c cannot be disabled in MATLAB.

"No. In older releases, Ctrl-C could be caught by TRY/CATCH; that changed a while ago. [When Ctrl-C was caught, you could get into a situation where there was no way, short of terminating the MATLAB process, to end your code.]"
That thread is still not quite authoritative with regards to compiled executables,
Unfortunate that Windows uses control-c for "paste".

Yes, quite unfortunate, I agree.
Once again thank you for your answers.

Although there's no way to disable it, you can keep stuff running even if it is called using a timer to execute your tasks.
Example:
t = timer('timerfcn','disp(''hello world'')','period',2,'taskstoexecute',10,'executionmode','fixedrate');
start(t)
It is going to display hello world 10x and if you click crtl+c in the middle the remaining hello worlds will still be displayed.
And what do you mean by GUI crashing?

Thank you Sean.
My GUI is compiled as a Windows stand-alone application; when I press Ctrl+C without an edit text or similar having focus I get a message from Windows stating that the executable has stopped working and the program closes.
