Mathematica doesn't currently support OLE automation.  However, there is
a simple example in the Mathematica distribution that does something
very similar to what you want to do using the MathLink protocol
developed by Wolfram.  If you've installed the MathLink Developer's Kit
from the Mathematica 3.0 CD onto your system (it's installed by
default), then look in the following subdirectory of the Mathematica
directory:

  Addons\Mathlink\DevelopersKits\Windows\UnsupportedGoodies\vbfe32

There's not much documentation that I'm aware of on using MathLink from
within Visual Basic, but the sample program here offers a good starting
point for a basic GUI front end.
