loExcelSheet.UsedRange.Rows.Count

?

I found that UsedRange could sometimes include empty cells (probably because they were accessed and cleared at one point), which may wreak havoc on certain things I'm trying to do. That's why I prefer to use the End property, which will always get me to the last non-empty cell (at least from what I've experienced).

Laterness,
