DataSource Controls :: What Is Better: Connecting To DB With One Stored Procedure To Get Two Table At Once OR Connecting...

May 20, 2010

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.

DataSource Controls :: Connecting To SQL Server In Visual Studio 2008 Using Code - Error: 25 - Connection String Is Not Valid

Feb 2, 2010

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.

Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:

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: SQL Network Interfaces, error: 25 - Connection string is not valid)

However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.

DataSource Controls :: Website Not Connecting To Database

Mar 8, 2010

Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. I have set up a db locally which mimics the production DB, THe production db and website has no has no issues.

THis used to work till i had hard disk failure and had to reinstall all software and do the db from scratch. Used the table scripts and ran the aspnet_regsql. I am using sql server express 2008 asp.net 3.5 I am using custom provider for Roles and custom membership provider for Memberships. Pretty sure the problem is in the db permissions, though I have set up Users in the Security of the DB.

Forms Data Controls :: Connecting A DropDownList To A DataSource?

Jul 13, 2010

I have a problem with connecting a DropDownList to a DataSource.

The scenario: When I add am item to the database (I do this using a GridView/ObjectDataSource / SPROC) I want to update a DropDownList that lists this items as well.This DropDownList is linked with another ObjectDataSource. Now, I listen to the RowCommand event of the GridView and in a certain case I refresh the DataSource of the DrpoDownList and do a DataBind to the DropDownList afterwards.

The strange thing is, that when I take a look at the DropDownList's Items-Collection during the Page's OnPreRender event handling, the items collection contains the new entry but the new entry is not rendered, i.e. when I take a look at the rendered HTML the <option></option> entry for the new value is missing.

After another postback to the page the entry appears in the DropDownList?

SQL Server :: TCP Error When Connecting To SQL Server Via User Control

Feb 4, 2011

We 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.)
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
at System.Data.SqlClient.TdsParserStateObject.WriteSni()
at System.Data.SqlClient.TdsParserStateObject.ExecuteFlush()
at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc)
at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async)
at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result)
at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)
at System.Data.SqlClient.SqlCommand.ExecuteScalar()
at [Our Namespace.OurMethod](String someParam)

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; }

Configuration :: Connecting To Whois Server

Apr 28, 2010

I have written a method for getting information about the ip-addresses of visitors to my web site. The method is called from Page_Load. It connects to the Ripe whois database and gets information about the ip sent. Everything works perfectly when I try it locally using localhost, but as soon as I upload the code to my web host it stops working, and I get the following error message saying that it can't connect to Ripe. The code is exacly the same as I use locally. (The relevant code is included in the error message below). I tried to contact my web host to ask them, but they said it was beyond their expertise...
