Hi peeps

I know loads of you have probably seen this error, or read about it before - so this shouldn't be a problem to answer.

I can connect and see my database (which is on my local machine) in Visual Studio (I am uing LINQ to connect and auto-generate entity classes). When I run my application it comes back with the dreadful error:

"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"

Now I've done everyting you are supposed to do:
1) Ensured remote connections are enabled, enabled TCP and named pipes
2) Started Browser service
3) Restarted servcies and/or Rebooted machine
4) Windows firewall isn't running as I have Kaspersky - but i've put in exceptions for the processes; and even turned Kaspersky off.

No joy.

As Visual Studio can connect and view the database, i was wondering if there is anything I have to configure on the ASP.net side of things?

I should point out that I am running:
- Vis Studio 2008
- Sql Server 2005 Service pack 2
- Vista business (incidentally I had no problems with the same set-up on diff machine running Vista Ultimate)

Confused | :confused:

I had this problem when I tried to connect from a server outside my local network to a server inside my local network
Are both the servers that are trying to talk to each other inside the same network?
Can you ping the address of the server you are trying to conenct to?

morning mate,

Yeah its all on my local machine

I had the same error on a diff machine connecting to a remote db, but sorted that by using the correct connection string.
This time, vis studio auto gens the connection string, which works in the designer, but not at run-time.

Hmmmmmmm

That would suggest that you need to write the connection string yourself, make sure all the basics are correct like username etc and also try using the name of the server instead of IP or viceversa

Yeah, I'll have to try that.

It's just funny how this worked without a problem on my other machine running Ultimate.
Damn computers, I knew I should have been a carpenter.

Does the View Source show txtdelivdate as it is or is the name mangled?

Can you quantify the situation? Are you getting any errors? Do you see the script emitted as part of the HTML?

Use RegisterStartupScript rather than RegisterClientScript.

Are you looking for something like this:

<br />
public void bg_color(TextBox txtbox_name)<br />
{ <br />
string stringvalue = txtbox_name.Text;<br />
<br />
}<br />
<br />
            string[] color = new string[] { "a", "b", "c" };<br />
            foreach (string i in color)<br />
            {<br />
                TextBox txt = new TextBox();<br />
                txt.Name = i;<br />
                txt.Text = i;<br />
                bg_color(txt);<br />
            }<br />

maybe something like that
