The whole point of using a Hash as an argument is so that you don't have 
to enter all the nil values. You might need to use the "Execute" method 
for that to work, I'm not sure.

Anyway, the best way to test what works is to attempt that command 
manually using IRB. Put together a test sequence with different ways of 
using OLEObjects, and then find out which ones work. Once you've played 
around with it a bit you'll be able to better understand the way it 
works.
