[Solved] ListView items add and General coding problems (Mp3 player)

[Tertitten]

This problem is now solved, see http://www.vbforums.com/showthread.php?t=560787
I'm working on a simple MP3 player and are stucked on some Treview.Click and Listview.Items.Add problems which I cant seem to get past.

What I'm trying to do is first with a button launch a FolderDialog to get folder path, when this is done I add the directories and subdirectories to tvFolders1 (Treview)
For the whole procedure for this see classes LoadFolderTree(), LoadDir() and tvFolders1_AfterExpand.
This seems to work just fine and no problems as far as I can see

The we add a feature where user click on the Treeview (tvFolders1) and we are supposed to do the following:
On tvFolders1_AfterSelect (when the user actually select something)
I am the trying to add Items and subitems to the lvFiles control (Listview)

Then we go trough the whole procedure of adding:
- Items = File Names
-- SubItems X 4 = ID3 info which we get from

            Me.lvFiles.Items.Add(FileIO.FileSystem.GetName(a))
        Next
        Dim _N As Integer
        With Player
            For _N = 0 To .currentPlaylist.count - 1
                lvFiles.Items(_N).SubItems.Add((Player.currentPlaylist.Item(_N).getItemInfo("Title")))

See the Class

Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect

For all the details.

Now adding items and subbitems goes just fine if I:
1. Do not clear the ListView lvFiles in the Class tvFolders1_AfterSelect
But I need that, I want the listview to be cleared before adding new items/subitems or we end up with an enormous list
2. Only add more items to the ListView without doing anything more

What happens:
If I clear the ListView lvFiles in the class tvFolders1_AfterSelect the application will simply freeze and crash after clicking on any item in TreeView tvFolders1

So basically somewhere in my code there is something causing this and that's were I need help, I where hoping someone could figure out what I need to do
I have pasted the whole code for that form because I suspect the problems are not in the adding/clicking on items but somewhere else, I do not know though.

There is also a "bug/another big problem" in the adding of items/subitems to the lvFiles ListView and that is that the first mp3 file only gets added with file/path and not ID3.

I would really appreciate some help with this problem, Thank You
