  put one listview and treeview control on a form, ive written this in c# and it may be or may not be what u want as. it first lists all drives in the list, then all folders under that, then listview gets filled with folder location.
  

  
  

  Code:

  
  public void FillTree(string Location)
         {
             //CLEAR HOLDERS
             treeView1.Nodes.Clear();
             listView1.Items.Clear();
             //FIND ALL FILES IN FOLDER
             System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(Location);
             foreach (System.IO.FileInfo f in dir.GetFiles("."))
             {    //LOAD FILES
                 ListViewItem lSingleItem = listView1.Items.Add(f.Name);
                 //SUB ITEMS
                 lSingleItem.SubItems.Add(Convert.ToString(f.Length));
                 lSingleItem.SubItems.Add(f.Extension);
                 }
             //FIND ALL DRIVES
             TreeNode DrivesTop = treeView1.Nodes.Add("Available Drives");
             DrivesTop.ImageIndex = 2;
             DrivesTop.SelectedImageIndex = 2;
             DrivesTop.Tag="";
             String[] drives = Environment.GetLogicalDrives();
             int NUM = drives.Length;
             int p = 0;
             while(p!=NUM)
             {
                 String OutPut = Convert.ToString(drives[p]); // + Convert.ToString(drives[p].Length);
                 TreeNode Drives = DrivesTop.Nodes.Add(OutPut);
                 Drives.Tag = Convert.ToString(drives[p]);
                 Drives.ImageIndex = 1;
                 Drives.SelectedImageIndex = 1;
                 p++;
             }
             
             //FIND ALL FOLDERS IN FOLDER
             TreeNode Main =  treeView1.Nodes.Add("Folders in : " + Location);
             Main.Tag = "";
             Main.ImageIndex = 2;
             Main.SelectedImageIndex = 2;
             foreach (System.IO.DirectoryInfo g in dir.GetDirectories())
             {    //LOAD FOLDERS
                 TreeNode MainNext = Main.Nodes.Add(g.FullName);
                 MainNext.Tag = (g.FullName);
             }
             //EXPAND TREE + GOTO TOP
             treeView1.ExpandAll();
         }
  

  
  

  
  now to call this , do
  

  
  

  Code:

  
  string Location = Convert.ToString(txtPath.Text);
  FillTree(Location);
  

  
  

  
  and to change the listview files when folder,drive is clicked use this
  

  
  

  Code:

  
  private void treeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
  {
     if (Convert.ToString(treeView1.SelectedNode.Tag) == "")
     {//DO NOWT
     }
     else
     {
         txtPath.Text = Convert.ToString(treeView1.SelectedNode.Tag);
         string Location = Convert.ToString(treeView1.SelectedNode.Tag);
         FillTree(Location);
     }
  }
  

  
  

  
  now as u posted in VB.NET and ive given code for c# , u can use this converter to change the code
  

  
  http://www.developerfusion.com/utilities/convertcsharptovb.aspx
  

  
  also u can remove the Main.ImageIndex = 2; + Main.SelectedImageIndex = 2; from the code as i have an imagelist associated with the treeview.

  It's been a long time since this was posted but I'm tying to implement it in C# Express and get a couple of errors:

  (1) FillTree(Location); Method must have a return type; (2} Identifier expected

  (3) The name 'txtPath' does not exist in the current context

  Would greatly appreciate feedback.

  Thanks.
