Question

How do i get ridd of this problem?? This is how my file is created: XmlTextWriter writer = new XmlTextWriter("jhk.xml", null); writer.Formatting = Formatting.Indented; writer.WriteStartDocument(); writer.WriteStartElement("user"); //writing a encrypted version of name and password writer.WriteElementString("name", crypt.Encrypt(tBUsername.Text.Trim(), "test")); writer.WriteElementString("password", crypt.Encrypt(tBPassword.Text.Trim(), "test")); writer.WriteEndElement(); writer.WriteEndDocument(); writer.Flush(); writer.Close();
