[RESOLVED]Sorting Items.

[Deny Winarto]

(See attachment)
I need help sorting items inside a listbox, the problem is, i'm using columns; so i don't know the algorithm if i want to sort it like this :
See the combo box in my program?
If "A" is selected, i want the items to be sorted based the values of A, descending down from the biggest number to smallest number, and the same applies the other letters.
ex :

A B C D
3 2 8 5
6 5 4 2
8 6 3 2
7 5 7 5
4 7 4 8
8 6 4 0

Select "A"

A B C D
8 6 3 2
8 6 4 0
7 5 7 5
6 5 4 2
4 7 4 8
3 2 8 5

Select "B"

A B C D
4 7 4 8
8 6 3 2
8 6 4 0
7 5 7 5
6 5 4 2
3 2 8 5

Select "C"

A B C D
3 2 8 5
7 5 7 5
8 6 4 0
6 5 4 2
4 7 4 8
8 6 3 2

select "D"

A B C D
4 7 4 8
7 5 7 5
3 2 8 5
8 6 3 2
6 5 4 2
8 6 4 0

(these numbers are just an example, they're not in the prog. )

Thx in advance.
