I am receiving the following error when using the PasswordRecovery control:

Specified cast is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Specified cast is not valid.


I do not believe it is a database connection error because all the other forms work in the website. I think it has to do with the web.config settings. Could someone please assist me with this issue? I have looked on the web for ideas but could not find anything that was related to this. Do I need to change a setting in my web.config? I did follow the same steps as in Beginning ASP.NET 3.5 but still no luck. I can create a user and then navigate through my website creating, viewing and deleting records without any issues. Any advice will be greatly appreciated. I am coding in VB.

Thank you,

Hi there,

Do you have any custom code in the page with the PasswordRecovery control? I can't imagine (although anything is possible) that the control itself throws this error, so something ight be going wrong in your code?

Hello,

Thanks for your reply.

I do not have any special code or code behind in the login page. The error is very odd because everything was working and now only the passwordrecovery control is not working.

Here is all the code for the login page.

<%@ Page Title="Log in to NetWorx Classifieds" Language="VB" MasterPageFile="~/MasterPages/MasterPage.master" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="Login" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="cpMainContent" Runat="Server">



<asp:LoginView ID="LoginView1" runat="server">
<LoggedInTemplate>
You are already logged in
</LoggedInTemplate>
<AnonymousTemplate>
<asp:Login ID="Login1" runat="server" CreateUserUrl="~/SignUp.aspx"
CreateUserText="Sign Up for a New Account at Classified Ads">
</asp:Login>
<br /><br />
<asp:PasswordRecovery ID="PasswordRecovery1" runat="server"><MailDefinition Subject="Your New Password for Networx Classifieds" >
</MailDefinition>
</asp:PasswordRecovery>
</AnonymousTemplate>
</asp:LoginView>
<asp:LoginStatus ID="LoginStatus1" runat="server" />

</asp:Content>

I can't see what the problem is. After I fixed the web.config file (extra spaces in the names under section groups) this code works fine for me, and I successfully get my password.

Do you get more information about where the error occurs?

Cheers,

Imar

Hello,

When I enter the user name in the forgot your password field and click submit I receive the error. It should postback and allow you to answer your unique question so a password will be emailed to you. Where in section group was there extra spaces?

I pasted the error below.




Exception Details: System.InvalidCastException: Specified cast is not valid.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Take a look at this:

>> System.Data.SqlClient.SqlDataReader.GetGuid(Int32 i) +51

Did you make any (manual) changes to the database? Looks like the user's ID is not a valid GUID.

There are lots of them. For example:

System.Web.Configuration.ScriptingJsonSerial izationSection

However, this is probably a forum bug that messes up your code.

Cheers,

Imar

Hello Imar,

I got the password recovery working. I had to re-create the database.

Thank you for your assistance.
