How can I do the following things from VFP via Excel?

1) Freeze the top row of a spreadsheet
2) Turn on auto-filter

I already have a reference to the excel object (loExcel) and can refer to the active worksheet (loExcel.ActiveWorksheet).

More generally, where can one find that kind of information so you don't need to ask the wonderfully helpful folks of the UT?

Grateful as always,

Alex
