Security :: Identifying Users Uniquely Via A Guid Or Other Techniques?
Oct 14, 2010
I am in the process of building a survey using asp.net and store these results into a database. Now this is what I am trying to achieve: - The survey is fairly long but will be split up in sections. - the way I have been told to develop this is to save each section into the database when the user clicks on a next button for example rather than clicking a final submit button and then submitting the results all in one go to the database. The reason being is for example, the user's browser crashes etc or if they accidentally close it down. I need to build it such a way that survey can remember who the person is.
I can't use windows authentication as it will be externally based, is there anyway I can uniquely identify people when they arrive on the web application e.g. by using a guid? Can it be guaranteed that the person who arrives on the application with a guid on that machine be exactly the same when he/she arrives again?

I am making a database with SQL server 2008 express edition and trying to make a GUID for new users signing up. I have the UserID field as a NVARCHAR(36) with a default value of NEWID() but all it keeps providing are all 0's for all 36 characters. How do I fix it where it provides a true GUID with all random letters/number?

I am using the asp.net membership.
On my site I have a Profile.aspx page.
In the code behind of this page, i get the logged in UserId (Guid) and pass this to a method in my DAL. GetUserByUserId()
In my database I have a Table called Member which the method gets the data from and displays details on the page about the user.
What I want to happen is when they have logged in and are diverted to Profile.aspx,
the page URL shows www.MyWebSite/Profile/UsersName
for example www.MyWebsite/Profile/JohnSmith.aspx
In my Member table I have FirstName and LastName columns or do I get the name from the membership table.
even better would be they go straight to www.MyWebsite/JohnSmith.aspx

I'm using .NET 3.5 and C# I've been searching a lot trying to find out how to change the default GUID that is generated by the membership provider to just use an ever increasing INT. Sounds like it's possible but I don't know what code I need to change.

I would like to insert a GUID into my table, then pass that variable to another page where I will use it in an email validation. Is this how you create a GUID?

We have a system where an administrator can login and create other users. If the administrator creates another user, then logs out and immediately logs back in with the new user information the UserID Guid is not available. If you log out and login again with the new username it works, or if you simply refresh the page it works.
Why does it not work on the first run?

I have an ASP.Net app with a lot of pages in it.My problem is to uniquely identify every page in my app. now the app might have pages with just the page name eg: home.aspx and can have pages with query strings eg:testPage.aspx?q1=1&q2=2.what i have been thinking is since every URL in my app is unique I could use the page name + all query string params concatenated(key and value) to identify the page uniquely.eg:home.asp home testPage.aspx?q1=1&q2=2 -> testpageq11q22.Is this the correct way to go or is there a better way to do it.The reason I want to do this is I need to add at run time some meta data information from a database for each of the pages.The PageID then becomes my unique ID which I can then map all my meta data info in the db to.
[code]...
would potentially point to the same page (where the optional param gives me some kind of meta information thats is not being used to generate the content on the page)

I have a server application that runs in a hosted environment but creates print jobs in the client's local network (behind NAT; the mechanics of this is not relevant).
In order to send the print job to the printer that is attached to the workstation, I need to identify the workstation. The users move around between workstations, so I can't permanently associate a user with a workstation/printer. The trivial solution is to require the user to identify the machine he is logging in from, for instance by selecting from a list, but that's an inconvenience and subject to user error.
Options I have eliminated:
Host header variables (nothing identifiable is sent) Cookies, in support of a user selection. This somewhat addresses the potential for user error, but not really. HTML5 DOM Storage - is not supported by the client's browser
Edit: I do have the option of puttnig this particular function (create a print job) into a thick client app. The app can then of course be configured and the problem goes away. But the user experience will suffer from having to switch between the browser and a Windows app.

What is wrong with this code? The error is Object reference not set to an instance of an object.
I have the below code in my class, then on the login page i need the GUID so i can perform a lookup in one of our custom tables. But then the error above pops up before the page even loads at the line Guid guid = (Guid)userInfo.ProviderUserKey;

As working with ip address in Sql Server needs some Efforts than mysql b'cos it Doesn't has INET_ATON() functionality. even though we create a Function to do that. But as per Requirement if ip address and postid should be Unique with One Post Question. than its some more complex to implement. so i need a solution without compromising my Disk space, 4 Tiny int field for ip address can be used but comparison will be more Hard to achieve. b'cos it is a composite primary key.

Scenario: I have a complex Asp.net app serving various units through programmatically constructed control collections in HttpModules. Some of these controls use Asp.NET Ajax.
Across many different units, ScriptResource.axd averages a transfer size of ~27k.
I have a ceiling that only allows ~3k for it.
There definitely isn't time to retrofit all the Ajax functionality with jQuery or hand-rolled js functions or whatnot. We already have the .axd coming over with gzip encoding (uncompressed it's more like 97k). It's often cached, but that doesn't matter: I have to hit a hard, low, externally-imposed limit on first-request total transfer size... markup, scripts, images & all summed up a-la firebug. I've been avoiding the .axds, but there really isn't anywhere else to shave bytes, and I have 24k to go.
Possible approaches: I'm not yet using Asp.NET 3.5 SP1's compositescript functionality, but I figure that would only save on request/response headers, and I'm not even sure headers count against me.
I don't have any other ideas other than something radical, like creating a response filter that uses reflection & some dictionaries to figure out what js functions are actually needed, and only emit those. I could cache the resulting list for each unit, since I have a low response time ceiling as well, and I don't think the .axds change from one request to another. Is this feasible? Any other ideas? ...what if I buy beer for the hero with a solution?

what MVC stands for,but if I'm already developing .NET websites without it,is there any reason I would need/want to use it?is it designed for people who already have experience with developing in an MVC environment and wanted a ".net"version of it?Is there some "head-to-head" comparison of MVC against other programming environments or techniques that have been written? It seems like what I might gain in development speed I might lose in flexibility.maybe I just don't understand what all the fuss is about.hence this post!

Say I have a single page/form with a search facility (i.e. a textbox plus 'Go' button) and a login facility (username, password and 'Login' button).
Is it possible to identify within the Page_Load event which button the user has clicked - i.e. 'Go' or 'Login' - can I somehow use the 'Source' and/or 'e' parameters to identify this?
I can direct both buttons to different OnClick event handlers or direct both to the same handler and identify the button using the Id or text properties but I'm curious to know whether the button can be identified at the Load stage.

Let us assume the following relationships (diagram). A FundCompany has Funds, and Accounts. There is also a FundAccount which creates a many-to-many relationship (as well as other attributes at the relationship level) between Accounts and Funds. Lastly an Account has one or more Beneficiary.The FundCompany is an aggregate root as it's at the top of the pyramid. Neither Account nor Fund can exist without the FundCompany. FundAccount cannot exist without both Fund and Account; does that make them both aggregate roots? Or is Fund still the only aggregate root, having to go through it to perform operations on FundAccount entities? The fact that the Account also has Beneficiaries, which cannot exist without the Account, does that also signal Account being an aggregate root?
All of the entities on this diagram will require CRUD operations and screens in my application. The reason I'm bringing this is up is most often every UI screen will store the ID of the row/entity it's referencing. So for example a user clicks "Details" on a table with Funds, I might need to retrieve a fund via its ID. My understanding is that if an entity needs direct access then it's an aggregate root in itself. However this would make a lot of entities aggregate roots by default.Based on the answers to above questions I have to map these operations to the proper aggregate root's repository.

I want to ensure a user isn't editing the same form data in two different browser tabs or windows (of the same web browser instance). The intention is to stop the user from accidentally overwriting their own data as they continue through a very long form process. On the server, ongoing data input through the screens is collected into the Session.
Assume for any browser, all tabs and windows run in the same instance of it (i.e. not each in a separate process). Obviously the browser tabs and windows share the same cookies in this scenario so cookie modification seems out of the question for viable solutions. This is also the reason they are sharing the same session state.
Considering that the form is already created and this is one of the final touches, how can I use ASP.NET, hopefully easily, to oversee this "feature"?

I am looking for a fast way (either by script or Query statements) that would enable me uniquely extract some tables from my database schema.
The tables I wish to extract have some unique columns like x and y coordinate columns and i want to extract only the tables that have these coulmns in them.
My database schema is very large with 100s of tables that i cant just go through the tables one by one.

i used security in login page which restricts all users who have not logged in to all pages. I need to restrict specific users to specific pages. I'm not using AspSqlService provider. So i cannot create roles and restrict automatically. And the pictures i use in login page are not visible @ runtime.
