[Access VBA Central] Finding a Windows username in VBA

[Heaton, Timothy H. (USD)]

I wrote a home-made Common Dialog Box for VBA, but I'm wondering if
there's a way to grab the current Windows username in VBA. I want it for
a shortcut to My Documents, as in:

ChDir "C:\Documents and Settings\" & UserName & "\My Documents"

Any ideas?
