Hi Portroe,

Let the user select the row(s) and calculate with the item(s) the user has
selected.

That can with the click event from a button (multiselect) or just with an
event from the listbox, by example selected itdex changed

I hope this helps a little bit.

Hi Portroe,

I thought yes in a multiselect, therefore you can have to look for the
selectedItems property

Set the control's 'SelectionMode' property to 'MultiExtended', then you
can use this code:

\\\
Dim Sum As Integer
For Each i As Integer In ListBox1.SelectedItems
Sum += i
Next i
MsgBox(Sum.ToString())
///

You can select items programmatically by calling
'listbox1.SetSelected(<item index>, True)'.
