Arranging Numbers in Descending Order using Arrays

Can someone help me on how to arrange numbers in descending order?
I'm using Visual Basic 6.0
What I want to do is that, when I click a button, the name of the person + the general average will be saved on a textbox, when I got all the average of the students, then when I click another button the textbox wherein the general averages were saved, will arrange into descending order.
Please help. :(

This thread in the Code Bank section has multiple methods of sorting an array.
