Invalidcastexception - Can't Access Custom Membership User In Code
Feb 2, 2010
I've wrote a custom membership provider and a custom membership user. So far so good, I can create users / login etc, but when I try to access the custom membership user in code like this;
Code:
Public Function GetOpportunities() As IQueryable(Of Opportunity)
'Dim p As CiseroMembershipProvider = System.Web.Security.Membership.Provider
'Dim _User = p.GetUser(System.Web.HttpContext.Current.User.Identity, True), CiseroMembershipUser
Dim _User As Curve.CiseroMembershipUser = Nothing
_User = System.Web.Security.Membership.GetUser() 'Dim _CurveUser As New CiseroMembershipUser
'Return From o In Me.ObjectContext.Opportunities Where o.ClientID = User.ClientID
Return From o In Me.ObjectContext.Opportunities Where o.ClientID = _
_User.ClientID Order By o.ModifiedDate Descending
End Function
I get this error:
Unable to cast object of type 'CustomMembershipUser' to type 'Curve.CustomMembershipUser'. When I put a quickwatch on the object System.Web.Security.Membership.GetUser() it is of type CustomMembershipUser. The quickwatch window generates the text DirectCast(System.Web.Security.Membership.GetUser(), CustomMembershipUser) when I click onto the properties, but reevaluating the expression raises the error.

I have an application that has been running for about 1.5 years. Suddenly, I got a bug report that the support team are receiving an InvalidCastException in the User ManagerUnable to cast object of type 'System.Guid' to type 'System.String'. The line this appears to be happening on is:
string queryStringID = Session["EditID"].ToString();
Guid providerUserKey =
new
Guid(queryStringID)
MembershipUser user =
Membership.GetUser(providerUserKey);
<--- here
This is a rather strange error as the value of the queryStringID is in fact a Guid generated by the Membership.GetUser(UserName).ProviderUserKey on the previous page. It doesn't seem to make any sense at all. I'm using the built-in SqlMembershipProvider with no changes. It's as if it isn't picking up that it should be using the overloaded function Membership.GetUser(object providerUserKey)Anyone else ever seen anything like this? I wouldn't normally post here unless I was absolutely stuck but I can't seem to find any relevant information by Googleing this one. Also, it's just started doing this. There was never an issue before. Very strange

I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure
public override bool ValidateUser(string username, string password) is
{
//select hashed password from db
return (EncodePassword(password) == dbpassword)
}
[code]....

Unfortunately, all the examples for Forms Authentication Code Behind w/ Custom Role and Membership Providers I find online are written with a VB.NET code behind and I need a C# code behind. I need a codebehind that will do the following:
authenticate user upon login button click
if user active_flag=0 (false) OR password!=@password, display error: "Access Denied"
if user admin_flag=1 & active flag=1 (true), redirect to admin_pageszipsearch.aspx
if user admin_flag=0 (false) & active_flag=1 (true), redirect to pageszipsearch.aspx
Default.aspx Code:
<asp:Login ID="LoginUser" runat="server" EnableViewState="false" RenderOuterTable="false">
<LayoutTemplate>
<span class="failureNotification">
<asp:Literal ID="FailureText" runat="server"></asp:Literal>
</span>......

in my app i want to create two types of users. (1) 'staff' (2) 'admin'
i have a page called registration which basically creates a user. i used the asp.net configuration wizard to create roles and set access rights to certain pages and this works great.
however, if i was to deploy this app then users wouldnt have access to the asp.net wizard therefore not be able to create users with roles/access.
so how can i do this in code? can i create a drop down in the registration page with two values (staff and admin) which will represent roles and then another drop down with access rights? (allow/deny)
how can i now program these drop down and make it work like i would normally do using asp.net configuration wizard?

For that, I made my own users and passwords tables and hashed the passwords myself. Now, I would much rather move to Microsoft's built in membership provider with asp.net in sql server. Does anybody know a good way to migrate over?
The only real idea I've had so far is to make both systems run simultaneously, then when a user logs in, validate them in my old system, then ask them to re-enter their password and save their new stuff in the microsoft's system... then clear the record out of my old system. Eventually, I would hope that would move everybody into the new system. But that seems annoying and messy. Is there some better way?

This is my first membership provider; I converted the sample provider [URL] to SQL. I created a vb class provider and put it into the App_Code folder. After it was created I tried to modify my webconfig but the error pops up. I don't know what else to try, I don't know if I have missed something

I'm using DotNetOpenAuth as my membership system, and the way I have it working now seems to be working quite well. What I'd like to do however is build into my website the ability to check user credentials against the AuthCookie rather than a session. In the membership provider, I can check for the username like this
string UserName = System.Web.HttpContext.Current.User.Identity.Name;
''# which returns the OpenId ClaimedIdentifier
What I'm wondering is if there is a way to extend this so that I can retrieve custom properties from the AuthCookie rather than having to create my own session object. Currently I have this setup.
UserSessionModal
Namespace Domain
Public Class UserSessionModel
Public Property ID As Integer
Public Property RegionID As Integer
Public Property Username As String
Public Property Slug As String
Public Sub New(ByVal user As User)
_ID = user.ID
_RegionID = user.RegionID
_Username = user.UserName
_Slug = Replace(user.UserName, " ", "-")
End Sub
End Class
End Namespace
BaseController (inherited by all controllers)
Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
''# Create a UserInfo object for the logged in user
''# and store it in a session state.
If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then
Dim user As Domain.UserSessionModel = New Domain.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User)
Session("UserInfo") = user
End If
Return MyBase.CreateActionInvoker()
End Function
Then in my views I do something like this
<%
Dim user As MyApp.Core.Domain.UserSessionModel = DirectCast(Session("UserInfo"), MyApp.Core.Domain.UserSessionModel)
%>
<%: Html.ActionLink(user.UserName, "Details", "Users", New With {.id = user.ID, .slug = user.Slug}, Nothing)%>
What I really need to be able to do is remove the Session stuff all together and just simply check the AuthCookie for my custom properties ID, RegionID, Username, and Slug. I can already get the "ClaimedIdentifier" out of the AuthCookie using HttpContext.User.Identity.Name... I just need to be able to extend it.

I'm using vs 2005 and asp.net 2.0 to create my website. Recently, I thought about applying membership instead of my customized security system in order to achieve higher security level and performance. At first thing went well, since it was easy to create/manage users and Role names from behind code, but when I came upon the "Access Rules" I faced what you can call it an 'obstacle' at least from my opinion.
The thing is, I don't want to use Asp.net Web Site Administration Tool to create and manage my access rules which I'm going to assign to each of my dynamically created Roles. What I want to be able to do is make a page where the Admin can create/manage his desired Role(s) and also, create/manage the Access Rules, then add such Access Rules to the previously created Role(s).
Now, what I need to know first is... is it even possible to do such thing in the first place? Because the way i understand it is, since the access rules are stored in the web.config of each folder/directory that you apply them on then it shouldn't be allowed to modify it from the running/published website.

I created a custom forms authentication and membership provider and it seems to work fine opening up in WAT, creating roles and adding users. Also when I in my mvc app use it to log users in, it works fine. However it seems to fail to determine a user's role (no errors, but just jump over User.IsInRole(...) lines and Roles.GetRolesForUser(); comes up empty. I got a gut feeling I did something wrong with my configuration, so for now I'll post just that:

I am trying to create a Forms Authenticated site and have already used the aspnet_regsql tool to create the necessary logic in my SQL Server DB to hold my data. Now, I am looking to create a custom Membership, User and Role provider for my DB model. I was looking at the following video: [URL]
Now, I get the concept on how to go about it but I notice that this guy uses custom DB Procedures as to the ones that are generated by the aspnet_regsql tool. Can anyone direct me on where I can find info on how to go about building the Membership, User and Role provider class using the DB structure that aspnet_regsql generates? So much junk on google that I am having a hard time finding good guidance.

how to implement the authentication and membership for a hobby project I'm working on. Tought I'd ask for opinions here. I started using the asp.net membership/authentication/profile providers. First off I want user's to "activate" their accounts, so upon registration I figured I'll set "IsApproved" to false, generate and email an activation code which I store in a user profile. User's won't have usernames, just log in by email address. While it's easy to pass an email address as username, I'm worried about user's having to change their email addresses (used for logging in) later.

We have created a Master page that inherits off the asp.net Master class.We have also got ui controls that inherit off the standard asp.net ui control class.Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use.However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?

I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this
MyControl myControl=(MyControl)userControl;
The reason i need to do this is because my user control has a custom property, person, I need to do the following:
myControl.Person=new Person();
essentially i need to simulate:
<%@ Reference Control="~/UserControls/MyControl.ascx" %>
which normally goes inside asp.net page or master-pages.any way of doing this in an Ajax Enabled WCF Service?

I have a user control called adminMenu and I use it in my index.aspx and all is fine, but I need to access a MenuItem in adminMenu and need to change NavigateUrl on the MenuItem. Tried this code with no luck:
MenuItem MaintenanceReports = this.adminMenu.FindItem("MaintenanceReports");
Not sure if I should be accessing adminMenu properties from controls code behind, but when I try from controls code behind was not able to access it either.

I'm new to ASP.NET and I don't exactly understand some features.
I have a custom membership provider TestMembershipProvider which inherits from MembershipProvider. It has the following CreateUser method:
[Code]....
It's absolutely simple code.Then I have two text boxes (login, password) and the button to register a new user. I thas a following code:
[Code]....
[Code]....
Authentication in web.config is set like this:
[Code]....
No matter what I write into textboxes, following error is being returned:
The password retrieval question provided is invalid.
I don't know why. Either in web.config or in get RequiresQuestionAndAnswer I have false value. When I instantiate my TestMembershipProvider and call CreateUser directly instead of using static Membership.CreateUser, it works fine. Do I have to use instance of my TestMembershipProvider or did I missed anything?

I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below:
public class SGIMembershipProvider : MembershipProvider
{
#region "[ Property Variables ]"
private int newPasswordLength = 8;
private string connectionString;
private string applicationName;
private bool enablePasswordReset;
private bool enablePasswordRetrieval;
private bool requiresQuestionAndAnswer;
private bool requiresUniqueEmail;
private int maxInvalidPasswordAttempts;
private int passwordAttemptWindow;
private MembershipPasswordFormat passwordFormat;
private int minRequiredNonAlphanumericCharacters;
private int minRequiredPasswordLength;
private string passwordStrengthRegularExpression;
private MachineKeySection machineKey;
**private DBConnect dbConn;**
#endregion
.......
public override bool ChangePassword(string username, string oldPassword, string newPassword)
{
if (!ValidateUser(username, oldPassword))
return false;
ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true);
OnValidatingPassword(args);
if (args.Cancel)
{
if (args.FailureInformation != null)
{
throw args.FailureInformation;
}
else
{
throw new Exception("Change password canceled due to new password validation failure.");
}
}
SqlParameter[] p = new SqlParameter[3];
p[0] = new SqlParameter("@applicationName", applicationName);
p[1] = new SqlParameter("@username", username);
p[2] = new SqlParameter("@password", EncodePassword(newPassword));
bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);**
return retval;
} //ChangePassword
public override void Initialize(string name, NameValueCollection config)
{
if (config == null)
{
throw new ArgumentNullException("config");
}
......
ConnectionStringSettings ConnectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]];
if ((ConnectionStringSettings == null) || (ConnectionStringSettings.ConnectionString.Trim() == String.Empty))
{
throw new ProviderException("Connection string cannot be blank.");
}
connectionString = ConnectionStringSettings.ConnectionString;
**dbConn = new DBConnect(connectionString);
dbConn.ConnectToDB();**
......
} //Initialize
......
} // SGIMembershipProvider
I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider.
