I am using aspx.vb to create a login page. I would like to create a remember me cookie using a checkbox that will help to remember user ID but will also allow it to be destroy if a different user ID wants to log in with the same computer, but i have no idea how to start. Any assistance? Thank you! :cry:

You might start with Forms Authentication in .NET. It automates the "remember me" cookie with the following method call.

FormsAuthentication.SetAuthCookie(userName, saveLogin);

Here's a place to begin learning more:
MSDN Documentation for SetAuthCookie Method

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            'Check if the browser support cookies
            If Request.Browser.Cookies Then
               'Check if the cookies with name PBLOGIN exist on user's machine
                If Request.Cookies("PBLOGIN") IsNot Nothing Then
                    'Pass the user name and password to the VerifyLogin method
                    Me.VerifyLogin(Request.Cookies("PBLOGIN")("UNAME").ToString(), Request.Cookies("PBLOGIN")("UPASS").ToString())
                End If
            End If
        End If
    End Sub

    Protected Sub BtLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        'check if remember me checkbox is checked on login
        If (Me.CbRememberMe.Checked) Then
            'Check if the browser support cookies
            If (Request.Browser.Cookies) Then
                'Check if the cookie with name PBLOGIN exist on user's machine
                If (Request.Cookies("PBLOGIN") Is Nothing) Then
                    'Create a cookie with expiry of 30 days
                    Response.Cookies("PBLOGIN").Expires = DateTime.Now.AddDays(30)
                    'Write username to the cookie
                    Response.Cookies("PBLOGIN").Item("UNAME") = Me.TbUserName.Text
                    'Write password to the cookie
                    Response.Cookies("PBLOGIN").Item("UPASS") = Me.TbPassword.Text
  'If the cookie already exist then wirte the user name and password on the cookie

                    Response.Cookies("PBLOGIN").Item("UPASS") = Me.TbPassword.Text
                End If
            End If
        End If

        Me.VerifyLogin(Me.TbUserName.Text, Me.TbPassword.Text)
    End Sub

Hi

you can refer the following code for remember cookie.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%
If request.form("remember") = "ON" Then
' Set cookie(s) to expire at later date, for example
response.cookies("username") = value
response.cookies("username").Expires = (Date+365)
End If
%>
