Access データベースで Visual Studio のログイン コントロールを使用しようとしています。2つの使い方がよくわかりません。これが私がこれまでに持っているものです：
ログイン.aspx:
<%@ Page Title="Login" Language="C#" MasterPageFile="~/EditSite.master" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Login ID="Login1" runat="server">
</asp:Login>
</asp:Content>
コードビハインドは次のとおりです。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
using System.Data;
using System.Data.OleDb;
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
ViewState["LoginErrors"] = 0;
}
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
if (YourValidationFunction(Login1.UserName, Login1.Password))
{
e.Authenticated = true;
Login1.TitleText = "Successfully Logged In";
} else {
e.Authenticated = false;
}
}
protected void Login1_LoginError(object sender, EventArgs e)
{
if (ViewState["LoginErrors"] == null)
ViewState["LoginErrors"] = 0;
int ErrorCount = (int)ViewState["LoginErrors"] + 1;
ViewState["LoginErrors"] = ErrorCount;
if ((ErrorCount > 3) && (Login1.PasswordRecoveryUrl != string.Empty))
Response.Redirect(Login1.PasswordRecoveryUrl);
}
private bool YourValidationFunction(string UserName, string Password)
{
bool boolReturnValue = false;
string constr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\TravelJoansDB.mdb;";
OleDbConnection con = new OleDbConnection(constr);
String SQLQuery = "SELECT UserName, Password FROM Login";
OleDbCommand com = new OleDbCommand(SQLQuery, con);
OleDbDataReader Dr;
con.Open();
Dr = com.ExecuteReader();
while (Dr.Read())
{
if ((UserName == Dr["UserName"].ToString()) & (Password == Dr["Password"].ToString()))
{
boolReturnValue = true;
}
Dr.Close();
return boolReturnValue;
}
return boolReturnValue;
}
}

change the connection string named "DefaultConnection" to connect to an instance

どんな助けでも大歓迎です。ログイン ボタンをクリックすると、ネットワーク関連のインスタンスが見つからないというエラーが表示されます。誰でも完全に制御できるように、フォルダーにセキュリティを設定しました。
