DataSource Controls :: Accessing Existing SQL Server Database With VS 2008?
Jan 13, 2010
I am attempting to write my very first ASP.NET application, it will simply display the contents of an SQL server database table in a Gridview. This is just a first step, my eventual intention is rewrite a set of VB6 applications I wrote some years ago. But I need to walk before I can run.
I have already created an SQL Server database containing all the tables used by the VB6 applications.
How do I link this database to my ASP.NET application. Previously (on another computer) I have simply opened "My Computer" and then navigated to the .mdf file (e.g. northwnd.mdf) and then dragged and dropped it into App_Data in Visual Studio. However when I try that on my own machine, with my own data, I get an "Access Denied" message.
How can I not have access to my own data on my own computer? What am doing wrong?
I am running Visual Studio 2008 on a Windows 7 Ultimate machine, with SQL Server 2005 Compact Edition (or which ever one installs with VS 2008).

I can see the AdventureWorks MDF file in my Server Explorer window in VS, but when I try to add this database file as an Existing item to my App_Data folder in the Solution Explorer it gives me an error saying that this file is in use. Is it possible for me to add my Adventureworks database to the App_data folder? I am running a 32-bit XP using SQL Server 2005 Express.

I started a new Sql Server 2008 with mixed authentication Windows and SQL SERVER AUTh... I created a new login account and use it to directly connect in SQL server managment studio BUT... when i create in VS2008 the connectionstring... everytime i try to open the DB connection i take an exception to the login... some screenshots show all the process ;)
LOGIN: admintvmaismais
PASSWORD: ex
Working to connect in SQL SERVER MANAGEMENT...
LOGIN STATUS ON SQL SERVER MANAGEMENTE
Now in VS2008 Web-Config I declare the connectionstring:
<connectionStrings>
<add name="SqlConnectionString" connectionString="Server=JP;Database=tvmaismais;User ID=admintvmaismais;Password=ex;" providerName="System.Data.SqlClient" />
</connectionStrings>
and When i try to open a connection like this:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString);
try
{
conn.Open();
...
}
catch (Exception e)
{
retorno = e.Message.ToString();
}
finally
{
if (conn.State == ConnectionState.Open)
conn.Close();
conn.Dispose();
}
I get this exception: Cannot open database "tvmaismais" requested by the login. The login failed. Login failed for user 'admintvmaismais'. What am I missing? What do i need to do, to get this login to work?

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

I have a development database and one in production. There are two different sets of data in each database. On my dev system, I have mostly dummy data that I test with and in production is the real data for my web application. I recently added a new feature to the app that required a new table, and a new field for a foreign key in an existing table. I now need to upload that new structure to the production database without overwriting the live data with my test data.
If I run the Database Publishing Wizard, and choose "Schema Only" will it import the new structure and leave the existing data alone, or will it drop the records in my production database tables?

I created and populated a database inside Visual Studio 2008 instead of using Management Studio.I need to run the script to create the schema for users and roles.The database does not show up in ASP.NET SQL Server Setup Wizard or in Management StudioThe only databases that do show up are master, model, msdb, and tempdb
Is there anything I can do to fix this or would it be easier for me to just create a new database starting in Management Studio and then connect to it from within Visual Studio?

I'm developing an ASP.NET user control in VS2008 that writes to a SQL Server 2005 database. I've published the control to a SharePoint 2007 MOSS page using the SmartPart addon. The control consists of a few text fields and a submit button that writes the contents of the text fields to the database. When I test the control in the Visual Studio debugger, it works fine. When I try to submit data from the SharePoint page, I get the error shown at the end of this post. Last time I saw this, it was a database permissions error, but I've granted my site's default application pool read/write access to my database. Does anyone have any idea what else the problem might be? Also, how can I double-check the credentials that the SharePoint page is using to access the database, since I still suspect that this is a permissions issue?

I have written a website in ASP.NET with a back-end database using SQL Express 2008. My database is created and put in the App_Data folder. It is ok when it runs on my local machine. However, when I upload to the web server, I got the error: An attempt to attach an auto-named database for file C:Documents and ettingsDesktopProject2_ISAM5337App_DataEvent.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. By the way, I notice a same probelm : When I move my project to a location which is different from specific path for my database, I got the same error message .

Migrating SSIS package from SQL Server 2005 to SQL Server 2008

Feb 25, 2010
Previous developers have developed a .SSISDeploymentManifest file (SQL Server 2005) to install SSIS packages which prompts a Package Installation wizard. I tried to install it on SQL Sever 2008 (it works on SQL Server 2005), but it failed with the error: "Storing or modifying packages in SQL Server requires the SSIS runtime and database to be the same version. Storing packages in earlier versions is not supported".
How do I install 2005 SSIS packages on SQL Server 2008? I have all the .dtsx files, not sure how to install them?
