Passing Byte arrays to a function...?

Ok, I know a funtion can return a byte array:

VB Code:

Private Function Woof() As Byte()
   'Blah Blah
End Function

Now why can't I do this:

VB Code:

Private Function Woof(ByVal Buffer() As Byte) As Byte()
   'Blah Blah
End Function

:confused:
But...ByRef works!!! Hmmmmmmmmm...any ideas?

Erm...you can't pass any kind of array as ByVal.

Passing an array ByRef is simple, you're only passing in the address of the first element (just like in C). However, if you were to pass in the array ByVal, you push the argument list onto the stack. Pushing an array of known size onto the stack could get really ugly, pushing an array of unknown size would be downright foolish.

Would you pass a byte array ByRef of ByVal using a string type as the parameter???

OK, I have 2 DLLs I want the same Enums in both...Should I just add a private class and just add all my enums publicly in there.
God knows why you can't define them in a module?
