View 3 RepliesI have a issue where I am trying to pull some records from an Access 2007 DB that has linked tables from a SQL 2005 Server. When I go to do this the browser IE8 just sits there and does nothing. THe little progress bar at the bottom moves about half way then that is it. It will sit there and show no errors or do anything. I have experience with connecting and manipulating Access and SQL server DB's but not through Access with linked tables from SQL Server. Here is test code below:

This does not produce an error or anything. The browser just sits there and sits there. Is there something I am missing?
I've a problem with my web application. I hosted a web site in IIS and initially its working good. After sometime ( i dont know the time diff exactly ), if i try to access my page its not working and after re-starting my application only its working. Let me explain about my project.
I've only 4 pages ( ex: main, a1,b1,c1 ) in my site. In main page i used IFrame to show other 3 pages by clicking the appropriate tab. Before this main page load, i'm connecting to DB (Oracle 10g) and i used "System.Data.OracleClient" class to communicate with oracle. Every time after retrieved data from DB i'll close the connection. Then i'll display the main page and assign other page url's to the tab.
Now the problem is after sometime if i access the main page, its not connecting to DB at all then i'll show some static message like "site is unavailable at this time". And i'm not using connection pooling concept. And also this problem is not occurring all time.
I have a window form app with reports that connects to an Access Database i had already build the project and every single report works fine without any problem, Here is what's stange, when i try to add a new report to the project and try to connect to the database i am getting 'Visual studio has a problem and need to close' i don't know what is the problem, i can open the database and run queries without any problem but whenever i want to connect my newly created report to the database it just failed. It does not give me a detail error so i can fix it.
View 2 RepliesI am creating a ASP.Net application in MVC architecture. I have to connect to a database on MS Access and be able to enter data into it. All examples I see use SQL Server. When I try from prject explorer Add New Item -> Data -> I am unable to find Drivers for Access Database.
From the Data Connections in Server Explrere window I was able to make a successful connection to the database.
Does MVC 2 support MS Access Database?
I have a WCF service hosted on win 2008 server. I'm using WAS to expose a named pipe endpoint on the service and have a client website that consumes the service. When i hit the website from a remote machine i get the following error:The pipe name could not be obtained for the pipe URI: Access is denied. (5, 0x5)Now if i hit the website ON THE SERVER it's being hosted from, using localhost in the url, it works fine. Clearly there is something i don't understand about what the named pipe endpoint is looking for. I tried running a trace from my service, but there is no output because the call doesn't even get to the service.

While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.
Can I connect to a ubuntu server, that is running mysql using ado.net or do I need a special driver?
View 2 RepliesWe have a MOSS 2007 custom web part based on a user control that queries a database cluster. When the connection to the database is made, we regularly experience the error below and have had to create a work-around in the code to retry the connection. We have 3 environments - development, staging and production; the error only occurs in production. The difference in the production environment is it is a farm with 3 WFEs and a SQL cluster, where development and staging are single machine instances. All are MOSS 2007 & SQL Server 2008. We cannot find what is causing this issue and I'm hoping someone else has experienced a similar problem and knows the cause.
This is the error that occurs frequently when the query is executed:
System.Data.SqlClient.SqlException: 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.)

More than one method will generate this, but this is typical code, note the retry work-around:
public static DataTable OurMethod(string someParam) {
const string query = "sp_OurStoredProcedure";
var resultsTable = new DataTable();
var connection = new SqlConnection { ConnectionString = OurDatabaseConnection };
var command = new SqlCommand(query, connection) { CommandType = CommandType.StoredProcedure };
var dataAdapter = new SqlDataAdapter(command);
var retry = 5; SqlConnection.ClearPool(connection);
while (retry > 0) { try { command.Parameters.Clear();
command.Parameters.AddWithValue("@someParam", someParam);
connection.Open(); dataAdapter.Fill(resultsTable); retry = -1;
} catch (Exception ex) { retry--; if (retry <= 0) {
LogError("Exception: DataAccess:OurMethod: *RETRIES EXCEEDED* " + ex, "error");
} else { SqlConnection.ClearPool(connection);
LogError("Exception: DataAccess:OurMethod: ATTEMPTS REMAINING " + retry + ". " + ex, "warning");
} } finally { dataAdapter.Dispose(); command.Dispose(); connection.Dispose();
} } return resultsTable; }
I have developed a web application in asp.net with C# in visual Studio 2005. And i used sql server 2008 as back end. When i run the program, it shows the following 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)
View 2 Replieshow do i connect visual web developer to sql server express 2008? in the Database Explorer, i right click on Data Connections, click Add Connection..., and in the Data source box i choose Microsoft SQL Server (sqlClient), which i'm guessing doesn't connect me to a database file, but to sql server express itself(?). in the server name box when i click the drop down box, there's nothing there and that's where i get stuck.

View 4 RepliesI am trying to retrieve some values from a Database built in SQL Server Express 2008 using .net Web Service.

Whenever i click run in Visual Studio 2008, it shows the startup page in IE that has two Methods (HelloWorld and authorizePassenger). When i click my method authorizePassenger it gets invoked and it asks me for input but when i input and click invoke IE shows HTTP500 error. The code above working fine in Standalone VB.net Application, so i guess i m doing the coding of Database correctly.
I have one web application which is configured to be use froms authentication.
But, I don't want to use SQL Authentication to connect to SQL server, I want to use windows authentication.
how would i go about measuring the number of users connecting a server...
i need to make a code for it..
So I've intalled SQL 2005 Express and Sql Server Management Studio Express (SSMSE). I don't have any problems connecting to it using Windows authentication. But I would like to set it up so that I can log in using Sql Server Authentication with a username and password.
But I'm getting an error message of "A connection was successfully established with the server, but then an error occured during the login process. (provider: Shared Memory Provider, error: 0- No process is on the other end of the pipe) (Microsoft SQL Server, Error: 233).
What I've done
I've created a new "Login" in the Security node. Provided all necessary role access level. Granted permission to connect to database and enabled login.
I've used the Sql Server Surface Area Configuration to set the Remote Connection type to "Using TCP/IP only" or "Using Both TCP/IP and named pipes" (tried both, but in either situation I get the same error message when attempting to login to SSMSE with the user name and password). I also made sure to restart the service.
I have recently combined my aspnet membership database and main website database into one database file, I'm happy with the schemas, stored procedures etc. (This is a development project not yet a production project.)
My problem is that I can no longer simultaneously connect to the database from Visual Studio if a user is logged in to the website.
EG:
Scenario 1: No user is logged in to the website. I can go to the Data Connection window in VS, choose "Add Connection" and then inspect the contents and schemas of the database. This is fine.
Scenario 2: A user is logged in on the website. I try to connect to the website in VS and get the error:
"Cannot open user default database. Login failed. "
Scenario 3: I am connected to the database in VS and nobody is logged into the website. If someone tries to log into the website they get the following error:
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
So it seems from the above that there can be only one connection to the database at a time? However this was not the case before I combined the membership database with the main website database. I could always make changes as a user logged into the website and at the same time see those changes through the connection in Visual Studio.
I've got this query UPDATE linkeddb...table SET field1 = 'Y' WHERE column1 = '1234' This takes 23 seconds to select and update one row But if I use openquery (which I don't want to) then it only takes half a second.
The reason I don't want to use openquery is so I can add parameters to my query securely and be safe from SQL injections. Does anyone know of any reason for it to be running so slowly?
I have an asp.net website that needs to connect to a dBase file on a remote server. The remote server has a ODBC System DSN connection configured but I have no idea how to connect to it.
