好的。所以我有一个简单的网站，其中包含一个用户名和密码文本框以及vb2008中的提交按钮，该按钮应该导致访问网格视图中SQL源表的新页面。我应该输入“mcobery”作为用户名和“密码”作为密码，当我这样做时，没有任何反应。我的代码背后有什么问题吗？我的用户名和登录页面不起作用
看看我的代码以及我的默认页面和它导致代码的页面。
这背后
Protected Sub butSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butSubmit.Click
Dim correctPassword As Boolean = False
'Establish the SqlConnection by using the configuration manager to get the connection string in our web.config file.
Using mySqlConnection = New Data.SqlClient.SqlConnection (ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
Dim sql As String = "SELECT password FROM MyUsers WHERE username = @userName"
Using mySqlCommand = New Data.SqlClient.SqlCommand(sql, mySqlConnection)
mySqlCommand.Parameters.AddWithValue("@userName", Me.TextBox1.Text)
Try
mySqlConnection.Open()
Using myReader = mySqlCommand.ExecuteReader()
If myReader.Read() Then
Dim password As String = myReader.GetString(myReader.GetOrdinal("password"))
If password = Me.TextBox2.Text Then
'Open page with users and roles
correctPassword = True
End If
End If
End Using
Catch ex As Exception
Console.WriteLine(ex.ToString())
End Try
End Using
End Using
If correctPassword Then
Response.Redirect("userAdmin.aspx")
End If
End Sub
End Class
我Default.aspx页
<%@ Page Language="VB" Debug="true" MasterPageFile="~/master.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="header" Runat="Server">

它应该是导致当您按下提交页面的代码。这就是所谓的userAdmin.aspx
<%@ Page Language="VB" MasterPageFile="~/master.master" AutoEventWireup="false" title="UserAdmin" %>
<asp:Content ID="Content1" ContentPlaceHolderID="header" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="navigation" Runat="Server">
<a href="Default.aspx">Default.aspx</a>
<br />
<br />
<a href="userAdmin.aspx">userAdmin.aspx</a>
<br />
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="main" Runat="Server">
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [MyUsers]"></asp:SqlDataSource>
<asp:GridView ID="UserRolesGrid" runat="server" DataSourceID="SqlDataSource1"
Width="399px" AutoGenerateColumns="False" DataKeyNames="id">
<Columns>
<asp:BoundField DataField="id" HeaderText="id" InsertVisible="False"
ReadOnly="True" SortExpression="id" />
<asp:BoundField DataField="user_logon_id" HeaderText="user_logon_id"
SortExpression="user_logon_id" />
<asp:BoundField DataField="user_full_name" HeaderText="user_full_name"
SortExpression="user_full_name" />
<asp:BoundField DataField="user_description" HeaderText="user_description"
SortExpression="user_description" />
<asp:BoundField DataField="user_password" HeaderText="user_password"
SortExpression="user_password" />
</Columns>
</asp:GridView>
</asp:Content>
<asp:Content ID="Content4" ContentPlaceHolderID="footer" Runat="Server">
</asp:Content>
这里是母版页的代码是否有帮助
