I have 2 databases one called DB1, and the other DB2. Both of them has exactly the same design (tables, procedures and etc..)
Now, I am using SQLMETAL to create the DataContext. problem is that there are two lines that direct to a certain database and so I cannot use the same code for both databases.
here is the code:
[Code]....
Now, What I am lookin for is a programmatically way to change this two lines (DataBaseAttribute and the connrection string) .
The easiest solution for me of course is to create the class twice, with the same code and just change manually what I need which is not what I am looking for.

I have a web site which uses one SQL database but the hosting company is very slow sometimes and I got database timeout, login and similar errors. Can I implement my code to use two databases simultaneously? I have stored procedures and the data is updated periodically.
EDIT:
Simply: When dbDefault is down and inaccessible I need to use dbSecondary so the web app keeps running. Ant these two databases must be always same.
EDIT:
Some errors:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.Cannot open database "db" requested by the login. The login failed. Login failed for user 'root'.
I would like to make a custom accordion, in which I have 2 panes, but where you couldn't open the second one until you clicked a validation button in the first one that would open the second...
I tried to just make a button that would hide the first pane but I cant get to make it work.
I have a user control is shown through a SimpleModal popup (JQuery), this user control gets some data from database and displays them (the details of a record).
The problem is that this user control makes a round-trip to gets the data every PostBack for the parent page even it's hidden.
I wonder if I could make it gets its data only if the popup is appeared.
I tried to put it inside a Panel with false for Visible property and change it to true when I open the popup, but it stil call Page_Load which gets the data from database!
i've learnt that you can create an auto-complete application using XML file, and XMLhttpRequest (JS, JS DOM).I was wondering if you can achieve the same thing using an .net application and some database info.Thinking about it, you might have to use AJAX to perform real-time auto-complete... But still, i dont know if it's possible that way.Aside of that, assuming that there is a .net solution, how professional site builders usually do that?
