解决了上面两个问题，相信大家心里一定有底了吧。下面就开始实现login.aspx页面。利用C#和SQL Server2000，创建一个webform页面，加入相应的控件。具体代码如下：
<%@ Page language="c#" Codebehind="login.aspx.cs"
AutoEventWireup="false" Inherits="secure.login" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>Secure Site</title>
<meta content="Microsoft Visual Studio 7.0" name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="javascript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5"
name="vs_targetSchema">
</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="login" method="post" runat="server">
<table cellSpacing="0" cellPadding="0" border="0">
<tr>
<td vAlign="top" align="left">
<asp:label id="Message" Runat="server" ForeColor="#ff0000">
</asp:label>
</td>
</tr>
<tr>
<td vAlign="top" align="left">
<b>E-mail:</b>
</td>
</tr>
<tr>
<td vAlign="top" align="left">
<asp:textbox id="username" Runat="server" Width="120">
</asp:textbox>
</td>
</tr>
<tr>
<td vAlign="top" align="left">
<b>Password:</b>
</td>
</tr>
<tr>
<td vAlign="top" align="left">
<asp:textbox id="password" Runat="server"
Width="120" TextMode="Password">
</asp:textbox>
</td>
</tr>
<tr>
<td vAlign="top" align="left">
<asp:checkbox id="saveLogin" Runat="server"
Text="<b>Save my login</b>">
</asp:checkbox>
</td>
</tr>
<tr>
<td vAlign="top" align="right">
<asp:imagebutton id="btnLogin" Runat="server"
ImageUrl="/images/w2k/login/btnLogin.gif">
</asp:imagebutton>
</td>
</tr>
</table>
</form>
</body>
</HTML>
界面做好之后，就开始编写提交按钮事件，首先需要注册该事件，代码如下：
private void InitializeComponent()
{
this.btnLogin.Click += new System.Web.UI.ImageClickEventHandler(this.btnLogin_Click);
.
.
.
}
事件注册好之后，自然就是编写事件处理函数了：
private void btnLogin_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
CCommonDB sql = new CCommonDB();
string redirect = "";
if((redirect = sql.AuthenticateUser(this.Session, this.Response,
username.Text, password.Text, saveLogin.Checked)) != string.Empty)
{
// Redirect the user
Response.Redirect(redirect);
}
else
{
Message.Text = "Login Failed!";
}
}
