I 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?
View 6 RepliesI have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local 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. I am trying to make sth that has almost no dependencies but well I can't avoid installing .net framework 4 everywhere...
Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?

View 2 RepliesWe 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. I'm using IIS 7.5 on my local machine to serve the development site while connecting to the development sql server on the other machine. Since I can't use the IIS aspnet account on the remote sql server and my assigned login is verfied working through sql management studio, what else can I do to get my developement site working again?
I have a ASP.Net program written in C# that uses a database stored in the AppData directory, the program works perfectly on my development (Win7SQL 2008R2) when I deploy to a Win2008R2SQl 2008 R2 server the program is unable to connect to the database. I'm using the connection string below. Several sites suggest I set the Application Pool to use 'Network Service' as this has Modify permission to the AppData directory, I have done this but it still won't work, another site suggested I Application Pool to "Load User Profile = True" but still no joy.
