You've declared stringLength as a pointer to an int, then assigned an
integer value to it. You don't want a pointer here, so leave out he *:
int stringLength = [string length];

The -setStringValue: method takes one and only one argument. In
particular, it does *not* take a format string and a variable argument
list, as you appear to expect it to do. To do something like that, you
need to break it into two steps:
NSString *newString = [NSString localizedStringWithFormat:
@"\"[EMAIL PROTECTED]" is %d characters long", string, stringLength];
[textLabel setStringValue: newString];
