Dear Alex,
The sample you show means a different case.
If you stuff through exception, it will only be caught by finally or except
block. In that case the caller of your function to check your function value
line will not be executed.
so you may write like that
begin
try
// do my stuff which may through exception
// in this case FALSE will be returned
// at the end of all
result := TRUE;
except
// By the way, this block eat all your exceptions, and do nothing,
it is not recommended
result := False;
end;
end;
Best Regards
Leigh Wanstead
