MS SQL Server :: Asp.net Provider Tables?

Renaming Membership Provider Tables

Nov 15, 2007

Hi, this might be a newbie question as I don't know too much about databases.My web host only lets me have 1 database, so I am trying to rename all the tables with a prefix, then import them to the server. I'm using MsSql-2005, VWD, Management Studio Express.My error when I run the .sql script is:Msg 208, Level 16, State 1, Procedure vw_aspnet_MembershipUsers, Line 3Invalid object name 'dbo.aspnet_Membership'.Msg 208, Level 16, State 1, Procedure vw_aspnet_Users, Line 3Invalid object name 'dbo.aspnet_Users'.Msg 208, Level 16, State 1, Procedure vw_aspnet_Profiles, Line 3Invalid object name 'dbo.aspnet_Profile'....I suspect that it is because I renamed the "aspnet_Membership" table to "Company1_aspnet_Membership" (I made a database diagram, then renamed the aspnet tables in Properties). Has anyone run into this before? Does anyone know how to fix it?

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.

Feb 20, 2006

Hi All,

I am new to dotnet. I tried connecting to the database MS SQL Server 2000. I gave the code like, the one below, in form load event,

SqlDataReader dr = null;

SqlConnection myConnection = new SqlConnection("Data Source=IP;Initial Catalog=name;User Id=uid;Password=pwd;");

myConnection.Open();

myConnection.Close();

But I could not connect. The error message highlights the line myConnection.Open() and displays the error

Provider: Named Pipes Provider, Error: 40 - Could Not Open A Connection To SQL Server

May 20, 2008

hi all

I realised this has been done to death, and so much information out there but I am still in a quandry.

I have had to rebuild my computer.

This is what I did

XP machine
using SQL Server 2005 Standard Edition
using Windows Authentication
NZ6(MSSQLSERVER)

straight default install all the way

unfortunately when ready to run reports from my instance(computer)
I received the error as in provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

thought I had it all okayed but obviously something not right

so ended up unistalling then - did the following:

Load SQL Server from disc1 and start install
failed on alter Counter Registry key error
fixed this from KB article (known error that can happen)
restarted
Went to Windows Update
check IIS is installed - tick is on - IIS - admin tools - make sure asp2 is associated - yes ok
Then back to install sql server - there is no instance set up yet
Disk 2 and setup .exe

All ok on Reporting Services, Analysis etc.

But once again all seems fine but still getting the error:

connection is all fine in Management Studio - eg I can see tables etc
connection is all fine in Business Intelligence - eg I can preview my reports
I then can deploy up to - NZ6
open NZ6
eports
report is there fine - but just errors

some simple little tick that I have not done!!

I seem to have checked and rechecked everything and obviously doing another re-install does not seem a logical step from here.
I will continue to check but if someone jump in and advise please would be great.

cheers
jewel

Provider: Named Pipes Provider, Error: 40 - Could Not Open A Connection To SQL Server

Apr 3, 2007

Hi,

Am getting the followning 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)"}

from my application where 3 service references had been added

and hav added this segment in app.config file

<configSections>

<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" />

<connectionStrings>

<add name="Connection String" connectionString="Data Source=DPA1W075Binstancename;Initial Catalog=SoapBox;Integrated Security=SSPI;"

</connectionStrings>

Solutions recommended for this were start running the SQL browser instance and enable Namespipes in Sqlserver configuration manager.Did both.. but nothing worked.

Still getting the same error..

Can somebody plz help me?

Handling Provider-level Errors From .Net SqlClient Data Provider

Jun 26, 2007

Hi,

After reading this helpful blog entry:

http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx

I think this might be a good place to ask the following question.

I am writing the error handling code for my data access layer for a web application. I am using the Enterprise Library Data Access Application Block. Although this supports generic database connections, I realized that I need to handle errors specific to each database type. Microsoft SQL is the only database type I am using for now, so I am using a try...catch (SqlException e).

In testing my code, I intentionally changed the instance name in web.config to a name that does not exist. I get the very popular error 26 - Error Locating Server/Instance Specified. This is returned as a SqlException, but the SqlError.Number property is set to -1.

Am I getting "-1" because the provider hasn't actually connected to SQL yet, so it doesn't have an actual SQL error number?
Can I assume that (SqlError.Number == -1) is always a fatal, provider-level connection exception?
Will the provider ever use another SqlError.Number of its own? Or do all numbers besides -1 come from the SQL sysmessages table?.
Is there a comprehensive list of what exceptions might be raised by the SqlClient provider, including #26?

The reason for all the questions is that in a web application, I want to prevent the end-user from seeing the "real" exception if it has to do with configuration errors. However, maybe there are other errors that the user should see and handle? It's hard to know without a full list of SqlClient provider errors, along with the SqlError.Number that each error maps to.

Thanks and regards,

Mark

Custom Log Provider Type Not Recognized As A Valid Log Provider

Mar 13, 2006

I am new to SSIS but I am learning fast. Any help is greatly appreciated.

I have written a custom log provider derived from LogProviderBase. I want to programmtically add the custom log provider to my package, but when I try this:

myPackage.LogProviders.Add("ACustomLogProvider");

I get the following exception:

"The log provider type "ACustomLogProvider" specified for log provider "{..GUID..}" is not recognized as a valid log provider type. This error occurs when an attempt is made to create a log provider for unknown log provider type. Verify the spelling in the log provider type name".

I have followed the instructions in BOL and as suggested in this forum, adding the DtsLogProvider attribute:

[DtsLogProvider(DisplayName="ACustomLogProvider", LogProviderType="ACustomLogProvider", Description="a description")]

Another way I tried is that I added a GUID attribute to my custom log provider class and then tried this:

Type aType = typeof(ACustomLogProvider);

Guid aGUID = (Guid)aType.GUID;

myPackage.LogProviders.Add("{"+ aGUID.ToString() +"}");

This also gives me the same exception "The log provider type ""{..the actual GUID for ACustomLogProvider..}" specified for log provider "{..a different GUID..}" is not recognized as a valid log provider type....

My questions are: Is it possible to add a custom log provider programmtically or must it be done through the SSIS Designer?

Must I deploy my custom log provider class for it to work programmatically? (I had perhaps wrongly assumed I would not have to deploy if I don't want it to show up in the SSIS Designer).

I would prefer to use a custom log provider instead of just logging within the SSIS event handlers because I can override the OnPostExecute, etc. but I cannot (can I?) override the specific event handlers like PackageStart, PackageEnd, etc because they are not exposed through DTSEvents.

Any help I would be very grateful for. Thanks.

Provider: TCP Provider, Error: 0 - No Connection Could Be Made (Need Help)

I try to connect to a SQL Server 2005 Express Edition via IP address. But anytime the application tries to connect to the database here is th error message I receive:

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: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)

There is the connection String code:

"Initial Catalog=myDataBase;" & _

"UserID=Username; Password=Password;"

Already checked

I have enabled the TCP/IP under SQL Server,
Under SQL Server Configuration Area, I have chosen the option Local and remote connection: TCP/IP only
I have verified that my firewall allows SQL remote and a Local Connection.

Now I don't know where to look or what I have to fix to continue. I will really appreciate if somebody can help me.

Thank you in advance.

A Transport-level Error Has Occurred When Receiving Results From The Server. (provider: TCP Provider, Error: 0 - The Handle Is I

Hi,

Basically the error that I am getting is in our test automation when running as non-admin on the box (regular user). We use .Net C# SQLConnection class to connect to SQL express 2005 impersonating with admin credentials. After getting the connection we try to execute a select command and it some time fails with 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)I tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.

Hello, I've a problem with a software developed in C# with the framework 2.0. This is the error I receive : The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" returned message "No transaction is active.". If I try directly to restart the process, it works fine. Is there someone who can help me ? This is the process 1. In C# --> Call of a Query : select from the linked server (db in sql 2005) and insert into a table SQL 2005 2. In the C# --> using (TransactionScope scope = new TransactionScope()) and insert in a table in SQL 2005 which is link server Thank in advance.
