ListView Items Add And General Coding

url...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)[code]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

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 tvFolders1So 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.
