admin_updatepwd.aspx.cs

《ASP.NET程序设计实用教程》源代码,这本书非常使用,有次源码更是锦上添花,谢谢使用

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using nsShop;	//因为用到了自定义业务对象，所以导入

public class admin_updatePWD:  System.Web.UI.Page
{
	public TextBox txtUserPWDold,txtUserPWD,txtUserPWD2 ;
	public Button Enter;
	public Label lblMessage;

	public void Page_Load(object sender, System.EventArgs e)
	{		
		//判断一下，如果不是管理员，就返回到首页
		if (DataUserLog.IsAdmin()==false )
			Response.Write("<script language='javascript'>top.document.location='../index.aspx';</script>");

		if (! Page.IsPostBack )
		{
			//利用DataUser对象，返回原来的值
			DataUser du = new DataUser(Convert.ToString(Session["UserId"]));
			txtUserPWDold.Text = du.UserPWD;
		}
	}

	public void Enter_Click(Object Sender,EventArgs E )
	{
		String strUserId,strOldPWD,strNewPWD ;
		strUserId = Convert.ToString(Session["UserId"]);
		strOldPWD = txtUserPWDold.Text;
		strNewPWD = txtUserPWD.Text;
		//调用函数更新密码
		DataUsers dus = new DataUsers();
		if (dus.UpdatePWD(strUserId,strOldPWD,strNewPWD)== true )
			lblMessage.Text="已经成功修改";
		else
			lblMessage.Text="旧密码错误";

	}
