Hy everybody i've created an event creating my users; doctyperelated Media and so on.

Now for better handling of the backoffice  i need to create an event wich is deleting the related mediafolder to the document. heres my code so far.

namespace ClientFolder 
{
    public class ClientFolder : umbraco.BusinessLogic.ApplicationBase
    {
        public ClientFolder()
        {
            Document.AfterPublish += new Document.PublishEventHandler(Document_AfterPublish);
            Document.AfterDelete += new Document.DeleteEventHandler(Document_AfterDelete);
        }

        void Document_AfterDelete(Document sender, DeleteEventArgs e)
        {
            if(sender.ContentType.Alias == "WebsiteContainer")
            {
                MediaType folderType = MediaType.GetByAlias("Folder");

                if(FolderExists(sender.Text))
                {
                    //now take the same folder from mediasection and delete
                }
            }

        }


        void Document_AfterPublish(Document sender, PublishEventArgs e)
        {

            if (sender.ContentType.Alias == "WebsiteContainer")
            {
                string websiteName = sender.Text;
                string myUser = websiteName;
                string myUserMail = "[email protected]";


                MediaType folderType = MediaType.GetByAlias("Folder");
                UserType demoUserType = UserType.GetUserType(2);


                if (!FolderExists(sender.Text))
                {
                    Media.MakeNew(websiteName, folderType, new User(0),-1);
                    DocumentType newDt = DocumentType.MakeNew(new User(0), "WebsiteContainer");
                    newDt.Description = "Seite des neuen Kunden";
                    newDt.Text = websiteName;
                }

                if(!UserExists(sender.Text))
                {
                    User u = User.MakeNew(websiteName, myUser, hashPassword("111111"), myUserMail, demoUserType);
                    u.addApplication("content");
                    u.addApplication("media");
                    u.Save();
                }

            }

        }



        private bool UserExists(string userName)
        {
            foreach (var myUser in User.getAll())
            {
               if(myUser.LoginName == userName)

                   return true;
            }
            return false;
        }


        private bool FolderExists(string folderName)
        {
            foreach (var item in Media.GetRootMedias()) 
            {
                if (item.Text == folderName)
                    return true;
            }
            return false;
        }

        string hashPassword(string password)
        {

            HMACSHA1 hash = new HMACSHA1();
            hash.Key = Encoding.Unicode.GetBytes(password);
            string encodedPassword = Convert.ToBase64String(hash.ComputeHash(Encoding.Unicode.GetBytes(password)));
            return encodedPassword;
        }


    }

Thanks for all help
