在ASP.NET中创建安全的web站点（配置） _ASP.NET技巧

<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!";
