How do you go about removing multiple items from a array list?
I'm using the RemoveAt() method to remove but doing that resets the ArrayList's index which cause me problems if the user selects to remove 1 & 3 out of a 3 list array since once it removes 0 the array list now just has 0 & 1.
ArrayList list = acontroller.ListForDisplay(articleModule.expireDate);
How can I get the "list" only display 10 items?
I don't want to set the number to display with stored procedure.
I've got another unrelated question, - from performance perspective, is it more efficient to sort data in stored procedure than sort using "icomparable" after I got a list of data into an arraylist? (30,000 record to sort.
i want to show the arrayliust items in the listbox, for that i had stored some data in array list, and now i want that if i gv any id which is in the array list its corresponding details are displayed in listbox. I had two fields ID, Name, and when i give id its corresponding name should be shown in list box.

How to handle this error
"An explicit value for the identity column in table 'UserActivation' can only be specified when a column list is used and IDENTITY_INSERT is ON."
I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.
[URL]
There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:

Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this

and then in the function I have no idea how to pass the values:

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

I've got a gridview that is databound with LINQ in the code behind. One column shows the id from the table. I would like to show a more human friendly product name that is associated with that id number but is from another table. Thought I had it figured out by entering a Template field in the gridview tags (in the .aspx page) and an item template within that with
<ItemTemplate>
<%Eval(Products.productName")%></ItemTemplate>
but when I try to build it says this can only be done in the context of a databound control.
Can I add this column within the gridview tags or does it have to be done from the code behind?
