		String sql = "delete users where userid=" + id + "";
		con = Dbmanage.getcon();
		try {
			st = con.createStatement();
			int num = st.executeUpdate(sql);
			if (num > 0) {
				return true;
			} else {
				return false;
			}
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			return false;
		} finally {

				con.close();
			} catch (SQLException e) {
				// TODO Auto-generated catch block
