Hi,

I know very little about either MzCOM or VB, so I'm reduced to reading
the MzCOM documentation and trying to find out where it might be
improved. Let's take it from the top...

The MzCOM docs say:

  In the Visual BASIC 6 environment, from the menu 
  Project|References (VB6), check "MzCOM 1.0 Type Library".  
  In Visual BASIC .NET, choose Project|Add Reference,
  and from the COM tab, select "MzCOM 1.0 Type Library".
  In your code, declare a variable, then assign to it:

    DIM schemeObject AS MzObj
    SET schemeObject = NEW MzObj

Does this much work? If so, are you able to call one of the three
methods About(), Eval(), or Reset()?
