execute membership validator after some tasks done

Maxxim · February 14th, 2007, 12:14 AM

Hello!

I have a standart html text to validate user login under membership class.

The html tag is:

Code:

<asp:LoginView... <asp:ImageButton ID="Submit" runat="server" AlternateText="Login" CommandName="Login" ImageUrl="~/images/go.gif" ValidationGroup="Login" meta:resourcekey="SubmitResource1" />

My problem is that i want to execute some tasks when a user click in the submite button and only when this tasks are maded execute validator login.
My question is:
How can execute this the "Login" command from code-behind?

Thanks!

I have an old application (asp.net 1.1) with users' accounts and I want to check if the current user is an old member, If it is and password match, then encrypte the password and insert it into memberships table then delete this account from old_accounts_Table and only then try to validate user.
So i need to call the login command for perform this last task!

If anyone could help i'll be thankfull!
(Forgive my bad english)

Hi there,

I a not sure I understand this:

Are you saying you still want to call normal validation first?

If so, you can handle various events of the Login. For example:

Protected Sub Login1_LoginError(ByVal sender As Object, _
      ByVal e As System.EventArgs) _
      Handles Login1.LoginError

  ' Custom code here

  End Sub

This event fires when authentication fails, so this is a good place to query your old system.

Alternatively, you can use the Membership API. For example:

Membership.ValidateUser(userName, password)

can be used to authenticate a user against the new system while:

Membership.CreateUser(userName, password)

can be used to create a new user.
Hope this helps,

It's not that case. I want to execute some tasks BEFORE Validator... Not AFTER!

I think i partially solve the problem:

Code:

<asp:LoginView ID="LoginView1" runat="server">
 <AnonymousTemplate>
   <asp:Login ID="Login1" runat="server" onauthenticate="AuthenticateUser" FailureAction="RedirectToLoginPage" Width="100%" meta:resourcekey="LoginResource1">
    <LayoutTemplate>
      ...

Public Sub AuthenticateUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs)

            Dim curLogin As System.Web.UI.WebControls.Login = CType(LoginView1.FindControl("Login1"), System.Web.UI.WebControls.Login)
            Dim txtUsername As TextBox = CType(curLogin.FindControl("UserName"), TextBox)
            Dim txtPassword As TextBox = CType(curLogin.FindControl("Password"), TextBox)
            'my code to see if current user is on old account database.
                'If it is, then pass him to new membership database
            If Membership.ValidateUser(txtUsername.Text, txtPassword.Text) Then


                If Not (Request.QueryString("ReturnUrl")) Is Nothing Then
                    FormsAuthentication.SetAuthCookie(txtUsername.Text, False)
                    Response.Redirect(Request.QueryString("ReturnUrl"))
                Else
                    FormsAuthentication.SetAuthCookie(txtUsername.Text, False)
                    Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath)
                End If
            Else
                FormsAuthentication.RedirectToLoginPage()
            End If

But this store a cooki for this user in cache when the Request.QueryString("ReturnUrl") is nothing

The code is:
FormsAuthentication.SetAuthCookie(txtUsername.Text , False)

So... I don't understand why the system store the cookie! :(

I have a loginView inside a MasterPage

I am not sure I understand. Aren't you telling it to store a cookie when the QueryString is Nothing?

Also, this:

If Membership.ValidateUser(txtUsername.Text, txtPassword.Text) Then

is checking against the new Membership system.

I don't see any code that uses the old system.

BTW, Personally, I would run the old code after the new code failed. That way when all users made the switch from old to new, you don't have to modify the code. It will continue to check the new system, but never has to access the old system anymore.
That way, you're favoring new users over old users in terms of performance.

Just a preference though....

Please corrects me if i'm wrong:

If i used:

Code:

FormsAuthentication.SetAuthCookie(txtUsername.Text, False)

I do not save cookie on client machine right?
But When I debug using this code, I make my login, then i close the browser and when I reopen the browser and return to my default page i'm still logged!!

It's that i don't understand!

You don't see the code that uses old system because I didn't wrote it yet! I'll place it before de "membership.validate"
Your idea it's possible and better if i don't want to change my code in future...

But i only have 250 users on my site, and i need that old system because they all have one way password (dashed) with asp.net 1.1

In 3 months I'll erase the code of codebehind and use standart membership because I'll erase the accounts of users that not enter in the system throughout these 3 months.

Thanks very much for your help on this! If you could spend one more minutes to see the problem with "FormsAuthentication.SetAuthCookie" I'll be very greatfull!!

Problem solved! :)
