I'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this:
Try If listbox1.Items.Count <> 0 Then Dim linedel As Integer linedel = listbox1.Items.IndexOf(listbox1.SelectedItem) listbox1.Items.RemoveAt(linedel) Else End If Catch ex As Exception MsgBox(ex.Message) End Try
If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.
I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.
