应该是这个问题：.net framework坏了 看看这句话就知道了Compiler Error Message: CS0234: The type or namespace name 'OleDb' does not exist in the class or namespace 'System.Data'
借个光问问：asp.net连接SQL的问题 我用asp.net做了一个系统登陆的页面.后台数据库采用的是SQL SERVER 2000 欲用SQL Managed Provider进行连接,代码如下: <%@ import namespace="System.Data" %><%@ import namespace="System.Data.SQLClient" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <title>欢迎使用万维软件-HR </title> <META http-equiv="Content-Type" content="text/html; charset=gb2312"> <script language="VB" runat="server"> Public Sub Page_Load(sender As Object,e As EventArgs) if not Page.IsPostBack then '网页组件初始设置 lblMsg.text = "" UserName.text = "" Password.text = "" end if End Sub Sub btOK_Click(sender As Object,e As EventArgs) Dim strConn,strSQL,getpsw As String
strSQL = "select UserID,UserName,Password,Preview from userinfo" strSQL = strSQL & " where e.UserName='" & UserName.text & "' "
dim myConn as SQLConnection =New SQLConnection("server=localhost;Integrated Security=SSPI;Intial Catalog=HR") dim myCommand as SQLCommand = New SQLCommand(strSQL,myConn) myConn.open() '取得OleDbDataReader对象 dim dr as ExcuteReader = myCommand.Reader() if dr.read() then session("UserName") = dr.item(1) getpsw=dr.item(2) if(Password.text<>getpsw) lblMsg.text="您输入的密码不正确！请重新输入！" UserName.text=dr.item(0) Password.text=""
else lblMsg.text="登陆成功" Page.Response.redirect("aaa.aspx") 'if dr.isdbnull(1) then ' session("UserName") = "" ' else ' session("UserName") = dr.item(1) end if 'Page.Response.redirect("MainFunction.aspx") 'MainFunction.aspx为主功能页面 else
System.Data.SqlClient.SqlException: SQL Server 不存在或访问被拒绝。就是sqlserver 名字写错了或者用户名和密码错误
我运行上面的代码怎出现这样的问题？ Server Error in '/samples' Application. --------------------------------------------------------------------------------The resource cannot be found. Description: HTTP 404.
