I have additional thoughts for the class code ( my God, you're extra OOP :) for later (such as a selection itself is a range object and you could just say :
...selection.value = 0, .selection.clear etc).

But for the Excel task. Instead of checking window via WinAPI try checking files RW openability (been there done that:)

lnHandle = fopen(pcFile,12)
do while lnHandle < 0
 lnHandle = fopen(pcFile,12)
enddo
* Now release oExcel

If you get the window way, take window id of worksheet not Excel itself (and I bet you do it much better than I).
And check your email frequently :)
