Why this warning in IDE?

rdufour

Dim Myfiles() as string
Myfiles(0) = "filename1"
I get a warning on line myfiles(0)=.. that myfiles has been used before it
has been assigned a value a null exception may occur. Obviously this is bs,
since I am in the process of assigning a value at that instant in code. How
do I prevent this warning from appearing? Maybe I should code this in a
different way?

Any help would be appreciated.

Bob,

You get this warning because you haven't set size of array MyFiles. If
you do this you won't get worning.
