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)....

I want to display it like this on an asp.net page.
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 "

0 news items found
N news items match your search criteria: 'string'" displayed

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?

I need to do some performance testing for an ASP.NET MVC application and specifically want to measure how many database queries each HTTP request results in. The data access layer is using LINQ-to-SQL. I'd like to be able to automate the tests so am looking for a good way to be able to do a before and after count of the number of SQL queries. The possibilities I can think of are: A performance monitor counter for the ASP.NET process, A system table in the MSSQL database that can be queried before and after each page request, A property somewhere in the System.Data.SQLClient namespace that tracks the number of queries executed by the process. Has anyone done this before and can perhaps point my down the right path?
