Directory.GetDirectories(dataDirectory)

iis://localhost//w3svc//1//root//data and //localhost//W3SVC//1//Root//Data// anad also one back slash, same error result i took...

public void CreateFormsMenuItems(BarManager barManager, BarSubItem formsBarSubItem, ItemClickEventHandler formsBaritem_ItemClick, string dataDirectory)
      {
         foreach (string dirName in Directory.GetDirectories(dataDirectory))
         {
            BarSubItem barsubitem = new BarSubItem();
            barsubitem.Category = barManager.Categories["Forms"];
            barsubitem.Caption = Path.GetFileNameWithoutExtension(dirName);
            barsubitem.Tag = dirName;
            //baritem.ItemClick += new ItemClickEventHandler(formsBaritem_ItemClick);
            barsubitem.ImageIndex = 5;
            barManager.Items.Add(barsubitem);
            formsBarSubItem.AddItem(barsubitem);
            CreateFormsMenuItems(barManager, barsubitem, formsBaritem_ItemClick, dirName);
         }

         foreach (string fileName in Directory.GetFiles(dataDirectory))
         {
            BarButtonItem baritem = new BarButtonItem();
            baritem.Category = barManager.Categories["Forms"];
            baritem.Caption = Path.GetFileNameWithoutExtension(fileName);
            baritem.Tag = fileName;
            baritem.ItemClick += new ItemClickEventHandler(formsBaritem_ItemClick);
            baritem.GroupIndex = 1;
            baritem.ButtonStyle = BarButtonStyle.Check;
            baritem.ImageIndex = 4;
            barManager.Items.Add(baritem);
            formsBarSubItem.AddItem(baritem);
         }
      }
DirectoryEntry dataDir = new DirectoryEntry("IIS://localhost/w3svc/root/1/Data/");

I think this is more of an issue in an ASP forum.

hmmm, Yes Danny, but I think he has a problem in undertanding what virtual directory is!! What you are doing Mkn is going to shared folder on network not virtual directory!!
I'll search in this topic and reply you soon, but better go to ASP.NET forum and discuss that there http://www.daniweb.com/forums/forum18.html
