.Net help or COM alternatives?

Hello all,

With the help of some people on the list, I have made some progress
with using COM automation with Squeak.  I am still stuck with a few
steps, so I asking the list again, to see if anyone can push me in the
right direction.

I am trying to access a particular COM object from Squeak.  Most of
the indicators I can find, say to use it through the .NetBridge.  The
site <http://wiki.squeak.org/squeak/3773> shows how to turn a COM
object into a .Net assembly.  I have done this and that part works
fine.  The documentation for the COM object I am trying to access can
be found at <http://www.sagesoftware.com/education/webinar/MAS90ObjectInterface.pdf>.
 It has code in VBS in the documentation that works.  I also have
sample code in VB and C# that works against the original COM object.
I have the .Net assembly working to a point.  Once I get to a certain
point in the code, I can get no further.  The code is below.

Hopefully someone can nudge me in the right direction, as I have tried
to contact the author, with no success.  Or, alternatively, if anyone
knows a better way to access COM from Squeak, I am all ears.

The code is below, with the part that fails commented.  Thank you in
advance to anyone who can help me out.
