Directory empty?

Ok...I'm going insane.

All I want to do is check and see if a directory is empty or not.  
Ideally, I want a loop that checks every so many minutes for files.  
Once it see's that the directory is empty, I want a msgbox to pop up 
telling me it's empty.

Msgbox = no problem
While loop = no problem
Checking for no files in directory = me pulling out the rest of my hair.

Any ideas from you pros?
