I am trying to implement DotNetOpenid in my asp.net website. However, the more I try to read up on DotNetOpenid, the more confused I get. My initial goal is to allow user login process (similar to StackOverflow). attempted to get some help via this question http://stackoverflow.com/questions/3882248/dotnetopenid-tutorial/3895442#3895442but was unsuccessful (since I am not using MVC)How can I get a tutorial

Looking at the OpenID protocol, it appears that the relying party needs to send a request to the identity provider. In our situation, this is not exactly ideal since the identity provider is behind a firewall-- our server will not be able to make the request. However, the user accessing our website (client-side, e.g. javascript or redirects) would be able to. So my question is this: does OpenID support an identity provider behind the firewall? If not, is there a secure way of accomplishing this?DIT:The client has a web server behind their firewall. They have employees that visit our website and thus are able to visit our site and their webserver which resides behind their firewall-- our server, however, would not be able to.

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

I have a problem with a SessionVariable. I will explain what is happening:
1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !
2. In the Page_Load, I later fill a ListBox1 with foldernames.
3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)
The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?
if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

I've been working on building a back end on an access database that allows users to search records using a web search box. I've been able to successfully set up simple search query's but have run into trouble where multiple criteria with "AND" statements (OR statements would return too much to be useful). My problem is this, when all five text boxes are filled out the query returns records no problem, but if even one is left blank i get nothing what so ever. Is there any thing I can do in either SQL or VB to either ignore null values entirely or convert them to wildcard values?

FirstThreads.AddRange(Threads.Skip<Thread>(PageIndex * PageSize)
.Take<Thread>(PageSize));
I can't do this:
FirstThreads = FirstThreads.AddRange(Threads.Skip<Thread>(PageIndex * PageSize)

Here's the scenario, we've built a url shortener (that we use only to shorten urls for Twitter to our website), and we also track the number of times a url has been clicked. So, for example.. the url might be something like "http://ourshortdomain.com/x9Mr"
Now, in many cases, we see as many as 1000 or 2000 clicks per shortened url, but the referrer is almost always null. How can this be, if the only place we're handing out that shortened url is on Twitter? Shouldn't all the url referrers be coming from Twitter?...

.NET noob here (as in I know next to nothing, I'm trying to pick up some of the scraps left by my developer). Ok, I am getting this error on a number of my .aspx pages: Error while checking url '/': Key cannot be null. Parameter name: key Interestingly, I get this on my homepage on which the only .NET code is in the form of two includes, e.g: <% Response.WriteFile("/includes/footer.aspx") %> These includes in themselves only contain HTML, so I assume the issue can only be related to these or a configuration issue?
