One other note. As a general rule I try to find a way to do what I
want using built-in features. I figure that it's going to be faster
then writing the code in RB. :-)

That may well be the case, if order matters -- an assumption of
Dictionaries is that order doesn't matter.
However, there's nothing magic about the Keys function (nor the Values
function for that matter). It just loops through the dictionary and
gathers them up. You can do the same thing yourself almost as fast. I
have a StringKeys extension method I sometimes use:
Function StringKeys(Extends dict As Dictionary) As String()
Dim i, maxi As Integer
maxi = dict.Count - 1
Dim out() As String
redim out( maxi )
for i = 0 to maxi
out(i) = dict.Key( i )
next
return out
End Function
With that, your function as originally written would work (just use
StringKeys instead of .Keys). However, you're still converting your
dictionary into a pair of arrays; if speed matters, consider just
keeping them as arrays instead.
Best,
