Sorry, if this sounds like dumb question but I'm an excel programming noob.

Basically what I'm trying to do is determine what workbook(index wise) is
the one closing during the "Worbook before Close" method.

For example, lets say I have 5 workbooks open in my Excel session and I
close one of them. I could access them easily by saying
Application.Workbooks[1], etc. However, I just want to know if there is a way
to know which one I'm currently closing.

I can easily count my number of open workbooks using workbook.count but I am
not able to go from that to the actual index of the one I'm closing...

I'm doing this in C# if it helps but I can probably translate VB if someone
knows how to do it...
