ASP.Net课堂--期末复习

ASP课堂--期末复习


1、 建立网站,以班级+序号+姓名为名字(如“软件工程1班1好张三”)来建立网站。建立数据库test,其中包含stu_info表和goods_info表,stu_info表结构:(Done)

          stu_name    varchar(20)

          stu_pwd     varchar(20)

在stu_info表中插入一条记录(”zhang”,”zhang”)

  goods_info表结构:

       goods_name     varchar(50)

        goods_price     float

       goods_date     varchar(20)

       goods_images   varchar(100)

 

2、 新建login.aspx页面,要求在此页面中用户输入用户名和密码,当用户单击“登录“按钮时,判断用户的输入与stu_info表中的数据是否符合,如果不符合,弹出对话框提示”用户名或密码错误“,如果用户输入正确,将用户的用户名保存到Session,并跳转到goodsadmin.aspx页面。(Done)
