㈠ 用戶登錄 asp+sql源碼
資料庫建立一個表admin 3個列:Username Passwd oskey(用戶級別)
ODBC數據源創建一個sql的數據源與你建立的資料庫連上。
conn.asp
<%
set conn=server.createobject("adodb.connection")
conn.connectionstring="DSN=ccsw;uid=sa;pwd=1234"
conn.open
%>

檢查用戶界面:
<!--#include file=articleconn.asp-->
<%
dim rs
UserName1=request.form("UserName")'獲得登錄界面輸入的用戶名
Passwd1=request.form("PassWd")''獲得登錄界面輸入的密碼
set rs=server.CreateObject("ADODB.RecordSet")'建立資料庫連接
rs.open "select * from admin where UserName='" & UserName1 & "' and passwd='"&passwd1&"'",conn,1 '查詢該用戶名和密碼是否存在
if rs.eof or rs.bof then '當沒有符合篩選結果時,則執行下面的句子
response.write "<script language=javascript>"
response.write "alert('用戶或密碼不對!');"
response.write "javascript:history.go(-1);"
response.write "</script>" '用javascript腳本提示用戶
else '如果符合條件的時候
session("UserName")=RS("Username") '新建session,值等於表單傳來的用戶名
session("KEY")=rs("OSKEY")
response.write"<SCRIPT language=JavaScript>alert('登錄成功');"
response.write"this.location.href='admin.asp';</SCRIPT>"
end if '結束if語句
%>
㈡ asp.net C# 登陸頁面 源碼
程序不復雜,去網上當一個
㈢ 誰有會員登錄系統網頁代碼+mysql資料庫(5頁就好)
給她錢了
㈣ php寫一個登陸界面並且保存到資料庫,實現1天免登陸,求源碼
login.php
<!doctype html public "-//W3C//dtd html 4.01 transitional//en" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title> New Document </title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<meta name="Generator" content="EditPlus">

<body>
<form name="form1" method="post" action="confirm.php">

<p>密碼:<input type="password" name="pwd"></p>
<p><input type="submit" name="b1"></p>
</form>
</body>
</html>
㈤ C#如何運用ACCSEE資料庫製作一個登錄、注冊的界面,代碼是怎麼樣的
不知道你有沒有使用過SQL Server資料庫,其實語句都是一樣的呀,只不過鏈接的資料庫的字元串不一樣。
SQL Server資料庫:string connectionString = "Data Source=localhost; Initial catalog=JXC_DB; User Id=sa; Password=sa";
Access資料庫:string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="Access資料庫路徑";
還有,就是操作資料庫的命名空間和類有所區別。如
SQL Server資料庫:using System.Data.SqlClient;
Access資料庫:using System.Data.OleDb;
僅此而已
㈥ 求一個visual studio2012編寫登錄界面與sql server2012資料庫連接的源碼
網上很多這樣的代碼吧,網路一下sqlconnection你就發現新大陸了。
㈦ 求c#注冊登錄界面源代碼(全部包括SQL資料庫)
我寫了一個登錄的程序,界面也做的還可以,寫了號幾天呢。20分把這么多代碼寫給你不太可能吧,這里也放不下
㈧ 求html登陸界面代碼,要連接資料庫的
<p
style="font-size:
45px;
color:
#FF9;
font-weight:
bold;
text-align:
center;">用戶登錄
</p>
<form
name="form1"
method="post"
action="loginok.asp"><table
width="292"
align="center">
<tr>
<td
align="center">用戶名:
<label
for="user"></label></td>
<td><input
name="user"
type="text"
id="user"
size="15"></td>
</tr>
<tr>
<td
align="center">密碼:
<label
for="psw2"></label></td>
<td><input
name="psw1"
type="password"
id="psw1"
size="15"></td>
</tr>
<tr>
<td
align="center"></td>
<td><input
type="submit"
name="button"
id="button"
value="登錄">
<input
type="reset"
name="button2"
id="button2"
value="重置"></td>
</tr>
</table>
</form>
這是連接資料庫那部分的代碼,自己做的。下面是效果圖。之後還要做個登錄成功的跳轉頁面。還有前面有人提了,動態網頁要保存為.asp格式。
