I have the code below which does work, but I need to add further functionality to it. The functionality I want to add to it is the text I have commented in the code below.
Dim objSQLConnection As SqlConnection
Dim objSQLCommand As SqlCommand
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim intID As Integer = CType(Request.Form("ID"), Integer)
Dim strHeading As String = CType(Request.Form("Heading"), String)....
Before the if statement, I want to find out if the database already has records with the username in the strUser variable.

I have a problem that I cannot seem to resolve. We are using an access database to store data from a Quality Assurance Tool. I need to calculate an average on a specific column in the table, however the SQL statement needs to count the number of records that contain "0.1" and divide it by the total number of records in the table. This data is then displayed in an ASP Page.
The field name is 1.
Here is the SQL:
StrSQL = "(Select Count([1]) FROM cservice Where [1]=0.1) / (Select Count([1]) FROM cservice) As questaverage "

I have the following search query
// GET /Home/Results/
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Result(string searchtext)
{
var search = (from n in _db.NewsItemSet
where n.headline.Contains(searchtext)
orderby n.posted descending
select n);
return View(search);
}
}
The search works and displays a record if a record containing a keyword exists, I am struggling however to implement a feature where when the search is returned it says for example:
0 news items found
N news items match your search criteria: 'string'" displayed

I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.
