[python-win32] creating a Word AddIn based on the Excel one

[Kieran Martin]

I tried to create a really basic Word AddIn based on the Excel example
(which works fine for me).  I've pasted the code below. 

 

Apologies for my general ignorance - I've trolled the Archives looking for
something close but no dice.  I've had luck making an Excel AddIns in the
past and can make my way round the Word Object model, VBA et al. But I'm
really winging it with the COM stuff.

 

Thanks in advance to who-ever takes a look at this .
