You need an exception handler around the code in question.
Have a read in the help about exceptions, but something like this should
suffice :
line of code...
line of code...
line of code...
TRY
line(S) of code that causes the violation
EXCEPT
On e:exception do
Showmessage('Whoops, error '+e.message);
END
