How can I get the exact ID of a user that is logged into a site?
I'm using the login and registration controls created by Visual Studio 2010, in the database the unique identifier is in this 28e8957e-00b8-4e75-bec9-2b90e640962d for example how can I return the exact one to be used in an SQL command for example?
I am creating a few web services for use with a mobile application. My current site uses asp .net membership and one of the web services will validate username and password.
In the web service I get passed uname and pword and just use
Code:
If Membership.ValidateUser(username, password) = True Then
Return "True"
Else
Return "false"
End If
Is there a similar way to get the userid without logging the user on or do I need to create a Stored procedure?
I have a gridview nested inside a Loggedin Template so when a user logins it will display their own details (name, address etc) When i attempt to run this i get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:

I need to insert a declaration in the codebehind function below that will make the variable "UserId" equal to the "logged-in user". In what way do I need to change the code below (elsewhere in the project, I successfully make reference to basically the same code and make the UserId equal to logged-in user by using this handler expression inside an image control: ImageUrl ='<%# Eval("UserId","Image.aspx?UserId={0}")%>'...But in the case below, the function is not fired by this expression, but rather by CustomValidator).
Sub ValidateImage(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
If Request.QueryString("UserId") IsNot Nothing Then
' Get the connection string from Web.config.
Using conn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabaseConnectionString").ToString())
' Create a command object.
Dim cmd As New SqlCommand()
' Assign the connection to the command.
cmd.Connection = conn
' Appendy the parameter to the SqlCommand and set value.
cmd.Parameters.Add("@UserId", SqlDbType.UniqueIdentifier).Value = Guid.Parse(Request.QueryString("UserId"))
' Set the command text
' SQL statement or the name of the stored procedure.
cmd.CommandText = "SELECT Avatar FROM aspnet_Membership WHERE UserId = @UserId AND Avatar IS NOT NULL"
' Set the command type
' CommandType.Text for ordinary SQL statements;
' CommandType.StoredProcedure for stored procedures.
cmd.CommandType = CommandType.Text
' Open the connection.
conn.Open()
' Convert the returned result to a bytes array.
Dim bytes As Byte() = DirectCast(cmd.ExecuteScalar(), Byte())
If bytes IsNot Nothing Then
' Set the HTTP MIME type of the output stream.
Response.ContentType = "image/jpeg"
' Write a string of Binary characters to the HTTP
' output stream.
Response.BinaryWrite(bytes)
' Send all currently buffered output to the client.
Response.End()
Else
args.IsValid = False
End If
End Using
End If
End Sub
I'm trying to get the current logged in UserId Value, using this code
[code]...
But, I getting an error (NullReferenceException), I did set a url authorization on the page that i try to get the logged in user information, witch is info.aspx, and I made the login.aspx control to be redirected to the info.aspx after the login process, But the info.aspx only shows me (access in denied), how can i make this page knows that i am already logged in?
i am trying to show a list of users of my application "school", when admin logs in then he can view all the users in list but when school principals logins, he should get only users of his school, So i thought to get the current loggedIn userId first and then by that userId i'll get schoolId since userId is foreign key in school table...once i'll get the schoolId i can show the members of that school.
But my problem is how to get the UserID of currently loggedIn. I'm using MVC 1.0 Asp.Net -- "Membership" if my logic above is wrong then tell me the alternate good idea, so that principal can see only his users list.
So I have been trying to pull the userid of whoever is currently logged in and match it to another table that it is a fk in. I have some code that should work but I get an error that says specified cast is not valid in line 10.
here is the code I have behind file:

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

Our application lets the administrator create new users. Since the administrator is logged in, I have set Logincreateduser = false so that the administrator is not logged out even after creating the new user.
The problem is :I need the userid of the newly created user to store additional details of the user in another database table. I see that i can get the username using Createuserwizard1.username; but how do I get the userID?
I would like users to upload a profile picture when they register, and to then show that picture in a picture box control when they are logged in based on that specific user.
View 1 RepliesI deployed a website where a logged user or an anonymous user can select data and download a XML file. The website generate the XML file in the server and then deliver it.
It works fine in my development environment, but after deployment, the anonymous user can download the file, but the logged user receive this error:
System.UnauthorizedAccessException: Access to the path 'd:HostsLocalUserheringerwebsiteUpload20110107094051.xml' is denied.
It is weird that as anonymous i can do it.
The website server help states this:
"Grant write, modify, delete access rights on website's folder
Your website executes under unique user account that by default has full control over the website's folder.
So your application can create, open, read, write and delete files and folders inside of your root folder.
There is no need and no way to change this permissions.
If, when running ASP.Net application, you still unable to create file or update it, you have to check your Web.Config file for "<Identity impersonate..." tag and remove it.
The only exception is when the application tries to modify a file or folder in "Application_Start" event of Global.asax file. This is by design that user authenticated only after the Application_Start even. Before the user is authenticated your website runs under an identity of Application Pool which is "Network services". That account doesn't have access to the folder of your website.
To make it work you eather have to move the code that tries to modify files or folders out of the "Application_Start" event of the Global.asax file or inside the event you'll need to impersonate your user by code."
But i am not using impersonate and the tag is not in my web.config.
I have the membership provider and the create user with tow steps, one of the steps contains a custom registration form, for each created user data will be in the database, and there is an account page shows the data that the new created user did insert during the registration process on the custom registration page,
the problem, when the user is created and logged into his account page, this account page shows only the information for the first created user, not the info on the logged in user , but the logged in user data still saved in database and not showing on his account page?
This is web.confg code:
<?xml version="1.0"?>
I have table called ROLE with fields (id,name,permission) example values (1001,madhu,hr)
I have another table called LOGIN with fields(id,DOB,password) example values(1001,24101989,madhukumar)
What i want is , if i login using the LOGIN table ,it check the id and permission in the ROLE table , if the permission is 'hr' it enable to access the menu , or if the permission is any other it just print the error message ("no permission")
Note: menu is placed in master page , but login is not in the master page ...

when your using ASP.NET Wizards to create a login, it uses a set of auto generated tables using the aspnet_regsql.exe tool...When you create a user using the wizard it generates a very long userID
"a40cf936-1596-4560-a26c-450792e2c8c0" I want to add users using another program that connects to this database... but how does visual studio auto-generate this ID. I want to auto-generate it as well
Is there any way to get the UserId of the curently loggedin user? Please help.
View 5 RepliesThe app requires user (mainUser) to login. Once logged in, the user can create users (subUser). I use the CreateUserWizard Control for this. I need to get the UserID of the subUser. HOw can I do this. I'm not sure of how to do it without confusing ASP of which userId I want. Is this a case for sessions? Or is there a more direct way?
