I have done a small conversion of vb to vb.net before and I can say that
every other line needed changing. There are significant changes between
the languages although they are trivial in most cases. I do not believe
you can just wrap them up in classes as MS would have done so already.

Not so because I am developing a Gnome scripting engine for all gnome
To sum up what I am creating :
*A non-visual bonobo object that any gnome application can embed.
*It will have properties for selecting a grammar (these will be xml
files). One advantage of using xml here is if say the VBA implementation
did not support a function that you needed then you could just edit the
xml file to add support for that function.
*It will have properties for specifying the application specific objects
using xml (I.E. in Excel you have the Application, Workbook and Range
objects. For something like Rhythmbox you might want objects for
*The bonobo component will generate events/signals whenever an
application's objects properties or methods are used in the script. That
way the application can interact with the script engine.
* The component will parse and syntax check scripts prior to converting
them to python.
A future bonobo object that I would like to create as well would also
include a mini IDE that can be embedded into any Gnome app. This would
use things like Scintilla to provide syntax highlighting for the
selected grammar. Also provide debugging for the scripts etc.
