Checking if not equal

Hey guys, Im looking for some help with some code. I need an If statement that first checks to see if a string has any letters in it. What I have is:

If Len(featuretwo) 'does not equal' 0 Then

Just curious what expression I need to put in place of 'does not equal'.
I tried:

If Len(featuretwo = Not 0 Then

That one didn't seem to work

Nevermind guys, I got it. Thanks anyway though!

use:

If Len(featuretwo) <> 0 Then

or

If Len(featuretwo) > 0 Then

because Len is never less then zero
