decremental for,,,each

[Colmag]

I've use a for...each loop to move items in a listview
upwards, and now i want to write a routine to move items
down.

For this, i need to do a for...each starting with the
last item in the list and ending with the first.

Any ideas on how to do this?

I tried for ages before posting, and almost as soon as
i'd posted i sorted it. Isn't that always the way?

Instead of a for...each i used a for...next with a step
of -1. What was throwing me was how to use the
for...next variable with the listview, which i did with:

Dim lvi As ListViewItem = ListView1.Items.Item(variable)

Instead of "for each lvi in listview1.items"

If there's a way of doing this with for...each, i'd still
like to know, as i'm learning at the mo'.

You could use a For-Next for that:

For i As Integer = ListView1.Items.Count - 1 To 0 Step -1
Dim li As ListViewItem = ListView1.Items(i)
'Do stuff...
Next

Jan,

Thanks for the info. You must have posted while the
server was sorting my own reply!

It's great to hear a solution that matches my own, good
for the confidence!

Can not be done with for-each. Use
For index = lastIndex to firstindex step -1
instead.

Thanks. Confirmation of what can't be done is just as
useful as knowing what can (saves me wasting time!)

Are you just trying to sort?
Can you be a little more specific?

is this what you want?

Private Sub MoveDown()
Dim lvi As ListViewItem
For Counter As Integer = (Me.ListView1.Items.Count - 1) To 0 Step -1
lvi = Me.ListView1.Items(Counter)
'do something here
Next
lvi = Nothing
End Sub

Thanks to everyone for the great replies. I managed to
sort it about a minute after posting (typical...), but
posted as anonymous by accident. I used a for...next
with a step of -1. As i'm learning at the mo', I was
interested to know if it's possible with a for...each,
but it seems not.

Jared, i'm using the routine to reorder items in a
listview. I can select multiple objects, then click on
up/down buttons to move the items up and down the list.
