String is not null, empty, or empty string

Question

What is the quickest and easiest way (in Classic ASP) to check if a string has some string (that has a length greater than 0) i.e. NOT \"Null\", \"Nothing\", \"Empty\", or \

Answer 1

Here's a one-liner that dodges all the trouble with Null by concatenating the value with an empty string. It works for Null, Empty, "", and, of course, strings with actual length! The only one it doesn't (nor shouldn't) work for is Nothing, because that's for object variables, of which a string is not.

isNullOrEmpty = (Len("" & myString) = 0)
