>>>Hi All,

>>>I have a method that returns a string if there is no file in a directory. I have stepped through this and watched this line get set to an empty string but when it comes back to the calling line of code, it is null. I am missing something and wonder if it is the way I did the while statement. Any ideas appreciated.

>The problem with this Naomi is the fileName variable would never change since it occurs prior to the while loop. I need to reset fileName as what drives the loop. I agree it is a bit funky to read but why does fileName get set to "" and then be null when it gets back to here? I don't understand that.

Look closer to my suggestion. You need to re-assign this filename variable again inside the loop. I think it's clearer than assignment and comparision as you're currently trying. At least for me it's simpler to understand and maintain.
