Was there supposed to be a question hiding in there somewhere?

Not a question. However, if it were a question regarding what can a heavy traffic website handle the answer would still be "it depends." Availability and responsiveness are dependent on many different factors including the performance of IIS and then also of the sql db and the network. Many, many, different factors.

I dont see what your question has to do with ASP.Net - and you've posted it in two different places. In future pick ONE forum and post there please

Don't post in multiple areas. It's considered rude.
As I told you in QA, your problem is that the sql is dynamic so the number of return columns cannot be determined ahead of time. Use something other than EF for this one.

I have Visual Studio 2010 Professional which should have the chart control in the toolbox. It is checked as being in the toolbox for both web forms and windows forms, but it is not showing. Is there some way to fix this? My projects are VB.

You could always try adding it anyway in to your page and see if it takes or if you get an error that might tell you what is happening.

Ryan,
Thank you. I resolved the issue thus: Loaded Visual Web Developer 2008 and added chart control to the toolbox. Opened VS 2010, unchecked chart controls from the Add Controls Dialog. Then added them back. Voila! Now the chart control appears in the vs 2010 toolbox.
Windows update kept trying to install update for the control, and failed for 5 days. Now the update should work. Hope this helps anyone who is experiencing a similar problem.

i have a problem using the auto complete with oracle, when i use @SearchText i don't now how fix it
Imports System.Collections.Generic
Imports System.Data.OracleClient
Imports System.Data
Partial Class VB
Inherits System.Web.UI.Page
<System.Web.Script.Services.ScriptMethod(), _
System.Web.Services.WebMethod()> _
Public Shared Function SearchCustomers(ByVal prefixText As String, ByVal count As Integer) As List(Of String)
Dim conn As OracleConnection = New OracleConnection
conn.ConnectionString = ConfigurationManager _
.ConnectionStrings("conexss").ConnectionString
Dim cmd As OracleCommand = New OracleCommand
cmd.CommandText = "select SITIOSEDENAME from INV_SITIOSEDE where " & _
"SITIOSEDENAME like @SearchText || '%'"
cmd.Parameters.AddWithValue("@SearchText", prefixText)
cmd.Connection = conn
conn.Open()
Dim customers As List(Of String) = New List(Of String)
Dim sdr As OracleDataReader
sdr = cmd.ExecuteReader
While sdr.Read
customers.Add(sdr("SITIOSEDENAME").ToString)
End While
conn.Close()
Return customers
End Function
Public Function SearchCustomers() As System.String[]
End Function
End Class

You haven't told us what the problem is, but I'm guessing it's because you're using the wrong parameter prefix.
The OracleCommand class doesn't use @ as the parameter prefix; it uses : instead.
When using named parameters in an SQL statement called by an OracleCommand of CommandType.Text, you must precede the parameter name with a colon (:). However, in a stored procedure, or when referring to a named parameter elsewhere in your code (for example, when adding OracleParameter objects to the Parameters property), do not precede the named parameter with a colon.
cmd.CommandText = "select SITIOSEDENAME from INV_SITIOSEDE where SITIOSEDENAME like :SearchText || '%'"
cmd.Parameters.AddWithValue("SearchText", prefixText)

I've been looking around for some ideas or code for encrypting data like email addresses in c# for my MVC project.
I wrote some code in vb about 8 years back, wanted to beef it up this time, perhaps go 512K or higher. Cryptography is not one of my strong points. But I'm looking for suggestions on something rock solid.
[Edit]
The code I wrote is DES, guess I should go AES so I can use the Xeon CPU AES feature to make it faster, plus I'm now reading that DES is pretty unsecure.
I found this in code project. Not sure if I should adopt it or not. [Edit], I think I'll pass on this one and keep looking.

That is very similar to what I use and as far as I know, still very secure.

Is this forum for MVC too? or is there any separate forum for MVC?

No, since MVC is ASP.Net, this is the correct forum. CP has not created a specific MVC forum.

Hello
I am trying to use a DetailsView to insert a neew item into a db table.
The problem is, I organized all not knowing the table's schema a priori. I use a Gridview to visualize and update the table , and it all works correctly by binding dynamically the gridview to the table in the PageLoad event handler. I don't use any template.
When I try to do something similar to insert a new row using a dynamically bound detailsview , I correctly visualize the fields' names in the detailsview, but as I modify the values, and try to manage the insert event , I find into the DetailsViewInsertEventArgs parameter that the Values collection property only has the Keys subcollection correctly populated, but the Values are all empty . I would expect, but maybe I didn't understand well, the Values.Values subcollection to be populated with the values I inserted, just as find the Values.Keys subcollection populated with the fiedls' names. Is it due to the fact that I am bindingg dynamically ? is there a way to work around this limitation ?
