using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

{

info.name = Login1.UserName;
info.pwd = Login1.Password;

return info;
}

private void validate()
{
bool flag = bll.select(getInfo());

if (!flag)
{
ClientScript.RegisterStartupScript(typeof(Page), "", "<script>window.open('用户名或密码错误,登陆失败！');</script>");
}
else
{
ClientScript.RegisterStartupScript(typeof(Page), "", "<script>window.open('登陆成功！');</script>");
//ClientScript.RegisterStartupScript(typeof(Page), "", "<script>window.open('Navigate.aspx');</script>");
}
}
protected void Login1_Authenticate1(object sender, AuthenticateEventArgs e)
{
validate();
}
}

---------------------------------------------------------

public bool select(loginInfo info)
{
string sql = "select * from loginInfo where [name] = '"+info.name+"' and pwd ='"+info.pwd+"'";

//SqlDataReader reader = helper.ExecuteReader(sql);

//if (reader.Read())
//{
// return true;
//}
DataSet ds = helper.ExecuteDataSet(sql);

if (ds.Tables[0].Rows.Count > 0)
{
return true;
}

return false;
}

输入的用户名和密码已经传递到数据库，检索出数据存在数据库当中了，为什么点击登陆以后，页面给出的还是。。您的登录尝试不成功。请重试呢？？？？

麻烦知道的帮下，第一次做这个，不胜感激好心人。
