Thanks, that all makes sense, I didn't realise it did re-raise the exception
if it was caught. However I tried both options and it didn't catch either.
Here's the actual code.
try
device_id := strtoint(get_markitem(2,msg));
except
on EConvertError do
device_id := 0;
end;
I also tried
try
device_id := strtoint(get_markitem(2,msg));
except
device_id := 0;
end;
IT raises the exception when get_markitem(2,msg) returns a null string (
result = ''). (is this a null string??)
Thanks so much for your help
