Read values from a listview

[Freakshow]

Hi,

 

I have a listview in my form with 3 collums (Nr - Name - Type) and an unknown number of row. When i select a row, i want to read the value of the Nr collum.

To make a long story short: I have figured our how to add items in the listview, but i don't know how to read them :(

 

It's my first year programming at high-school so my knowlege isn't that big...

 

Thnx in advance

ListView1.Items(itemIndex).SubItems(subItemIndex)

Well i already tried that. But the problem is that you need to define the itemIndex to a indexnumer. But when you select another row the value of the indexnumbers dousn't change. So you keep on reading the same line. And that's not the point :)

 

Or am i missing something here?

use ListView1.SelectedItem to reference the currently selected item. So

ListView1.SelectedItem.SubItems(subItemIndex)

   Private Sub lstApp_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstApp.SelectedIndexChanged
       txtAppNr.Text = lstApp.SelectedItems.Item(0).Text
   End Sub

this should be the code then?

Well it works if you only select 1 and you do not select another again.

If you do, this error appears:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll
