One possible cause is that your asp.net pages are not inheriting from System.Web.UI.Page, i had that problem when i converted to .net 3.5, but i've never used IIS7 or win 2k8, so i'm afraid i cant be more help.
Alcohol the cause of and solution to all of life's problems.

I have problems to show images in a datagrid. I was looking for some answer and I found that if I use this code it should be work.
Dim Comm As New OleDbCommand(QPhoto, con.Con)
Conexion.Open()
Dim OledbRead As OleDbDataReader
OledbRead = Comm.ExecuteReader(CommandBehavior.CloseConnection)
Do While (OledbRead.Read)
Response.ContentType = OledbRead.Item("IDArti")
Response.BinaryWrite(OledbRead.Item("Image"))
Loop
con.Con.Close()
But, unfortunatelly it doesn't work. When I try to run this code, it asks me if I want to open or save and the both options don't do anything.
Could you help me?
I have the images in Access database and I want to display them in the datagrid with the information of each row
Please, help me I'm stressed out

I have two web pages , i am navigating from page1 to page2 with a query string . The problem is i don't want to show the query string value in the address bar , it leads to database hacking.
How should i overcome this problem ?
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

make another page, page a for now, a basic html page with a frameset that loads page 1, make page a the default page on the webserver and all they will ever see is whatever you call page a, but they'll interact with page 1 and when you navigate to page 1 to page 2 the address bar wont change and if you set the frameset up correctly no one will ever notice it. you could also put your querystring values into the session or viewstate and pass them that way.

Use View Source in the browser, and you'll see what id the elements really have.
You can use the ClientID property of a server control to find out what id it will get in the rendered page.
Despite everything, the person most likely to be fooling you next is yourself.

Wow, are you still writing classic ASP? Anyway, check permissions on the folders.
I didn't get any requirements for the signature

What is the best way to retrieve data from SQL Server 2005 for a performance hungry web site? I was thinking of using sqlconnection+datareader+stored procedures but I'm not keen on the idea of writing sqlconnection every time. I like using typed datasets but I really need the maximum performance for the site and I don't know about it's performance. What do you think? Should I go for my own DAL? Or are there good DAL components that I'm not aware of that I could use? Any opinion is appreciated.

Just declare one connection string at the top of the page
Then use stored procedures

Your best bet is to use a sqlconnection and datareader. You biggest bottleneck will often be your sql queries. So if you have data that doesn't change very often use System.Web.Caching...
Do not use typed datasets, they are a performance killer. If you want you can use class objects to represent your data and use generic lists instead of typed datasets.
Also, you can call one stored procedure to get all of your data. Just return multiple result sets and use reader.next
