Opening listview items with a double click vb.net - vb.net

Question

I want to open items from a list view with a double click.
Imports System.IO
Imports System.Xml
Public Class cv7import
Private Sub cv7import_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim caminho As String
caminho = "C:\Documents and Settings\Software\Ambiente de trabalho\cv7import"
lstvicon.View = View.Details
lstvicon.GridLines = False
lstvicon.FullRowSelect = True
lstvicon.HideSelection = False
lstvicon.MultiSelect = True
lstvicon.Columns.Add("Nome")
lstvicon.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize)
Dim DI As System.IO.DirectoryInfo = New System.IO.DirectoryInfo(caminho)
Dim files() As System.IO.FileInfo = DI.GetFiles
Dim file As System.IO.FileInfo
Dim li As ListViewItem
For Each file In files
li = lstvicon.Items.Add(file.Name)
Next
End Sub
Private Sub btnimp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnimp.Click
Dim caminho As String
caminho = "C:\Documents and Settings\Software\Ambiente de trabalho\cv7import"
Dim items() As ListViewItem = lstvicon.SelectedItems.Cast(Of ListViewItem).ToArray
Dim csv() As String = Array.ConvertAll(items, Function(lvi) String.Join(",", lvi.SubItems.Cast(Of ListViewItem.ListViewSubItem).Select(Function(si) si.Text).ToArray))
IO.File.WriteAllLines("C:\Documents and Settings\Software\Ambiente de trabalho\cv7import\teste.csv", csv)
End Class
That's the important part of the code, I was think of using onclick but I cant seem to get anywhere with it, any suggestions?
I also considered using and Open File Dialog but I dont think it can be done without the user's input of a path

Answer 1

I'm assuming that when you say open, you mean you want to open the associated file in the default program for that file type. In that case, you need to be storing the full path to the file in the list view. That can be accomplished via this code:
For Each file In files
li = lstvicon.Items.Add(file.Name)
li.Tag = file.FullName
Next
You will then need to add an event for the listview's double-click method. Within that event you'll want to look at the selected item and run the default program for it.
Private Sub lstvicon_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstvicon.DoubleClick
Process.Start(lstvicon.SelectedItems(0).Tag)
End Sub
