我的 default.aspx 上有以下代码
Label1.Text = Session("valueName").ToString()
以及我 login.aspx 上的以下代码
Dim strCon As String = ConfigurationManager.ConnectionStrings("Goed").ConnectionString
'Create Connection String And SQL Statement
Dim strSelect As String = "SELECT COUNT(*) FROM tbl_LogIn WHERE Gebruiker = @Gebruiker AND Wachtwoord = @Wachtwoord"
Dim con As New SqlConnection(strCon)
Dim cmd As New SqlCommand()
cmd.Connection = con
cmd.CommandType = CommandType.Text
cmd.CommandText = strSelect
Dim Gebruiker As New SqlParameter("@Gebruiker", _
SqlDbType.VarChar)
Gebruiker.Value = TxtUs.Text.Trim().ToString()
cmd.Parameters.Add(Gebruiker)
Dim Wachtwoord As New SqlParameter("@Wachtwoord", _
SqlDbType.VarChar)
Wachtwoord.Value = TxtPw.Text.Trim().ToString()
cmd.Parameters.Add(Wachtwoord)
con.Open()
Dim result As Integer = DirectCast(cmd.ExecuteScalar(), Int32)
con.Close()
If result >= 1 Then
Response.Redirect("default.aspx")
Session("valueName") = TxtUs.Text.ToString()
Else
lblMsg.Text = "Gebruikers naam en of wachtwoord kloppen niet"
End If
End Sub
但这似乎没有帮助。我没有得到任何错误或什么,任何想法?
