I know its better to use stored procedures than the asp.net sqldatasource control. But on an app like say amazon and ebay what is the best way to connect to a database (best practices) that multiple users will use: sqldatasourcecontrol,disconnected classes,or connected classes?(Programmatically or not}
View 2 RepliesI have created my site using ASP.NET Personal Starter Kits 3.5. I use Visual Studio 2008 only . .with its built-in SQL Server (2005 Express) ... my database in App_Data is ASPNETDB.MDF ...
I have created some of my tables also ....in ASPNETDB ..
In my local PC the site was running fine ...
But when I publish my site on production server it doesn't work and shows the following error

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

My hosting provider connection string ..
<add name="ConnectionString" connectionString="Data Source=69.16.253.19;Initial Catalog=usa_data;Persist Security Info=True;User Id=user;Password=pass" providerName="System.Data.SqlClient"/>

Can anybody tell em how to fix this ... !! I am very tensed since last 3-4 days
I built an ASP.NET 4.0 Web Site. It works perfectly on my development computer. However, when I deploy the web site to theProduction Server, which is a Win2003 Small Business with Sql Server 2000, the site can't connect to the database.
These are the different tests I've made:
I tried using Integrated Windows authentication and this connection string: Data Source=myServerAddress;Initial Catalog=myDataBase;Integratedsecurity=true; and the error I got was that NT Authority/Network Service couldn't open the database. So I added that account to my database users list and gave it the appropiate permissions. Nothing.I tried using Sql Server authentication, so I created a new database user with a password and changed my connection string toData Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;. Nothing. I still got the same NT Authority user message.I deleted the used I created in step 2 and used the same connection string, to see if this time I got an error saying something about my user, and indeed it happened. I got an exception saying that user myUsername couldn't log on. I then created the user again, ang got the NT Authority user message one more time.I created a console application that used the same connection string from steps 2 and 3, and it connected to the database witouth any problem, which made me think that my problem's got something to do with my Web.config.I tried enabling impersonation on my Web.config, and thos time I got the same error message, only referring to the user I logged in to Windows, instead of NT Authority/Network service. What else could I check? My Web.config is this in case it helps (I havn't really put anything into it other than what VS puts):

Problem: I need to move a local development database to the production server without any of the test data.
I am running SQL Server Express 2008 and SQL Server Management Studio 2008.
To create my ASP.NET Membership 2.0 system I created the DB initialy and ran aspnet_regsql.exe
I then added my own tables manually to store additional information.
I adjusted the web.config file with an application name.
When I ran a sript the application ID name was created and populated in the aspnet_Applications table. My script created a new member created and added to the admin role. Ok so everything go so far.
Now I want to move the local DB to the server. I know the connection string and can change this in the web.config.
My hosting company doesn't provide restore, so I don't think I can backup and restore
Q 1. What would be the best way to move the database across. Bearing in mind I need to clean the database out of test data.
Would it be just generate an SQL Script for the database and run it as a query on the server? And if this is the best way then do I need to set the permissions for the ASPNET user?
Q 2. What is the best way to clear out the data in the local database.?
I've got an MVC 2 application running on Server 2008 R2, IIS 7.5. The application runs without issues. I added ELMAH to trap unhandled errors, write them to a database and send emails. The ELMAH functionality works without issues on my development machine (XP). However, that same functionality does not work on the server. ELMAH fails silently so I'm at a loss to know why things are not working
View 2 RepliesI have created a web application and an SQL database using Web Developer 2010 Express. I have SQL Server 2008 and SQL Server Management Studio Express. In order to deploy the database to my hosting space I need to create a .BAK file from my new database. I think I can do this from with the Management Studio, but can't figure out how to get it to connect to the database. I have used Management Studio before to retore another SQL database and the only connection I see when I open the Management Studio is the old connection to the old database. How do I connect to my new database?

So, how do I get the Server Explorer to connect with a remote SQL Server database?

I am using Visual studio 2010 c sharp express and Sql 2008 express R2.I have added a database in the project to have all the data needed. When I use the release folder or the debug folder on other pcs the app doesn't run. Wherever I install SQL server (database and management) things are fine. I googled but I am not sure what to look exactly for and made a brief search here but with no results.

Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?

We have a database on our server, here at the office. We now want to create a asp.net website that will be accessible to the public.
Say the domain of the website is [URL] and it's hosted on a webserver of HeartInternet.
When someone connects to that domain, that webpage must be able to pull data from our server that is located here in our office.
In other words the webpage cannot just load data out of the MySQL database loaded on its server, but it has to connect to our server and get data.

View 1 RepliesI recently upgraded a WinXP machine that had been running VWD 2005 to a Win7 machine using VS 2010. The application targets .Net 2.0, but since the upgrade, I cannot get VS to connect to my database and this is the first time I've tried working on the site since upgrading, so no changes have been made to any code (with the exception of trying to change my connection string so I can connect). The specific error is:Cannot open database requested in login 'dbName'. Login fails. Login failed for user 'SqlLogin'The sql database is on another machine and I was assigned the login/password; I know the login works because I can connect to it with SQL Server Management Studio. Having read several posts and still having trouble, I tried to do a couple things. First I modified my web.config connection string, which looks like this:
[Code]....
When that did not work, I deleted the connection string from the web config and dragged a sqldatasource control onto a page and tried to use the connection string builder while in design mode. Then the error I got was:The database db1 does not exist or you do not have permission to see it. Would you like to attempt to create it?I'm not sure I understand that there is a problem at all, except that I upgraded the OS/IDE.
