Hi Sandi.
>I've been trying to figure out where to change the cFieldExpr property in the fields collection but I'm not sure where I should put the code - should I be looking at the sfgetfilter class or somewhere else?
You can put it in your own code sometime after the instantiation of SFQuery. Reference the oFieldCollection object of the SFQuery object. For example:
loField = oQuery.oFieldCollection.Item('customer.company')
loField.cFieldExpr = whateverDoug
