something like this:
make a new imagelist
add a image into it
then select your listview and go to the properties and select smallimagelist
and select the imagelist
Code: Select all
Dim li As New ListViewItem()
li.SubItems.Add(fi.Name)
li.ImageIndex = 0
Listview1.Items.Add(li)

Do you see the file Icons.vb? You can use that class to get the icon from a file.
Code: Select all
Dim Icons As New Icons(True) 'True = Big icons, False = small icons
ListView1.LargeImageList = Icons.LargeIcons
Dim item1 As New ListViewItem("file1.txt")
item1.ImageIndex = Icons.GetIconIndex("C:\file1.txt")
ListView1.Items.Add(item1)
If you have a file named 'file1.txt' in your C:\ directory, it will load the correct icon and add it to a ListView named ListView1.

Is it possible when you click a button that have a folderbrowsedialog it will show the icons after the folder has been choosen ? so it will work as the file you posted? just without the treeview

Code: Select all
Dim icons As New Icons(True)
ListView1.LargeImageList = icons.LargeIcons
Dim browser As New FolderBrowserDialog
If browser.ShowDialog() = DialogResult.OK Then
   For Each f As String In System.IO.Directory.GetFiles(browser.SelectedPath)
      Dim Item As New ListViewItem(System.IO.Path.GetFileName(f))
      Item.ImageIndex = icons.GetIconIndex(f)
      ListView1.Items.Add(Item)
   Next
End If
You could have that in a button, as long as you add the class Icons.vb from the file I uploaded to your project. I think it works, but I didn't test it.

I added this code to my button but no icons did show up and 2 folderbrowse dialogs showed up

Did it show any text at all? Did you have any other code in your button?
