Initialize Error Connecting To SQL Server Database
Mar 8, 2006
Newbie strikes again.. I'm attempting to connect to a SQL Server database (using VS 2005). My code generated no errors in the build but when I tried to access the database, I got the following message:
"The ConnectionString property has not been initialized."
My connection string is stored in my web.config file. My code goes as follows:
Dim strSQL As String = "SQL string stored here"
Dim objConnection as SqlConnection = New SQLConnection(ConfigurationManager.AppSettings("name of connection string is here"))
Dim objCommand as SQLCommand = New SqlCommand(strSQL, objConnection)
objConnection.Open()
Then I go on to open my reader and such. Where should I be initializing the ConnectionString property?
Hi, I am getting the following error when i am trying to connect to the database server installed on different box. "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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)" When i searched google, some postings suggested to enable the TCP/IP and Named Pipes Protocols from SQL Server configuration Manager. I did so and also ran mofcomp command. But even after doing this i am not able to connect to the server. Following is my connection string. <add key="conn2" value="Data Source=xxxxxxxx;Initial Catalog=xxxxxx_xxxxxx;User ID=xx;Password=xxxxxx;"/> Could any one please tell me what else the configuration settings i need to do in order to connect to the database from my application.
I've run into a bit of a database connection problem. I'm trying to connect to a SQL Server database. It compiles okay, but then while IE is loading, I get an exception error pointing out in the code saying 'Keyword not supported: 'provider'.
i tried to connect to a SQL Server Compact Database (version 3.5) with SQL Server Management Studio Express (Version 9.00.3042.00).
But i get the follwing error message (sorry, it's a german message):
..................................... Es kann keine Verbindung mit 'D:DocumentsVisual Studio 2008Projects\_ProduktivSuperkalibrator_PrototypenSuperkalibrator_PrototypenDatenbankDatabaseTest.sdf' hergestellt werden.

Is there a solution to manage Compact Databases in Version 3.5?
I've had some problems with Reporting Services and getting connected to the database server after configuration. I am now getting the following error message:
The report server cannot open a connection to the report server database. A connection to the database is required for all requests and processing. (rsReportServerDatabaseUnavailable) (rsRPCError)
In my Database Setup everything runs fine when I click apply except for the Setting Connection Info for Reporting Server this has a yellow triangle with a ! and says that the report server cannot access internal information.
I also have not been able to Initialize as there are no instances to initialize and none are created when I go through setup. Is there something I need to delete from the registry or the file system that does not get removed upon uninstall?
Hi guys, I created a database using SQL Server EXpress edition but now i need to use SQL Server Development edition. I cant connect to the database now? Anyone tell me what the problem is.
When i am trying to connect to SQL Server(Express edition) on production server i am getting 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: TCP Provider, error: 0 - No such host is known.)" My SQL connection string is like this which i wrote in web.config. <add key="conn1" value="Data Source=xxx.xxx.x.xxxyz,1433;Initial Catalog=abcdef_xyz;persist Security Info=true;User ID=xx;Password=xxxxxx"/> string constr = ConfigurationManager.AppSettings["conn1"]; SqlConnection con = new SqlConnection(constr); con.Open(); When i searched microsoft help to resolve this error, it suggested me to enable TCP/IP protocol for SQL server, i did that, but even after doing that i am still not able to connect to the database. Could any one please tell me what else i need to configure in order to connect to the database. Thanks
I get the following error: An error has occurred while establishing a connection to the server.

Hi Again,I have MSDE on ASP1.1 on a PC and have a logon page that uses a stored procedure to check my auth_user table, if logon and password exist then it returns (1) else returns (0).I used objparams.return to pick up the returned value and either server.transfer to opening page or label text message 'login not valid'. This is insde a try and the catch is another label, 'cannot connect to database'.Running on my local PC all is fine, transferred SP and table to hosting server, along with web.comfig set to the host servername, uid, password and database. On the host server all errors messages are returned. I have created a connection in my VS7 database manager to the remote host and the same happens after amending my connection string to run on the remote server.It clearly is the connection string, I am using the <appsettings> add Key to connect as I thought it would mean no change of coding in my pages when moving from Dev PC to Server. I have checked the hosting server setup and used the server name associated with the database (mssql3.securedc.com) , checked uid, password and database settings. Is there something I have missed like permissions, specific security settings on the host server (I have to go through a third party as the hosting is done through a friend of my client)?? Many thanksEarle
I've remoted into our domain controller which houses our SQL database. From there I've been using the Microsoft SQL Database manager to run queries. However, I would prefer to do this from my desktop and not have to remote in whenever I need to look something up. I've found that Microsoft Visual Studio Express 2013 can create a connection where I can do my work. I've created the connection (or I believe so). "Testing the connection" is successful and in the Database Explorer window I can see my database and the folders of tables, views, etc. However, all of these folders are empty..When I choose the database everything in the settings pops up and I use the same authetication I use on the domain controller..
Hi Am developing a web application in asp.net ,c# and Sql server 2005(management studio express). Am using VS 2008 version. Getting the following error while connecting to database. plz help me

I am trying to connect to a .sdf database. I am building a console application. First I got an error "Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)". Then I manage to solve "Unable to load DLL 'sqlceme30.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)". So wat is the possible error on my side ?
Hello, I'm tyring a simple piece of code to conenct to my database: SqlConnection con = new SqlConnection("Data Source=localhost; Initial Catalog=OrderingSystem; Integrated Security=SSPI"); try { // Try to open the connection. con.Open(); label1.Text = "<b>Server Version:</b> " + con.ServerVersion; label1.Text += "<br /><b>Connection Is:</b> " + con.State.ToString(); } catch (Exception err) { // Handle an error by displaying the information. label1.Text = "Error reading the database. " + err.Message; } finally { // Either way, make sure the connection is properly closed. // Even if the connection wasn't opened successfully, // calling Close() won't cause an error. con.Close(); label1.Text += "<br /><b>Now Connection Is:</b> " + con.State.ToString(); } When I try this, I get an error:"Error reading the database. Cannot open database "OrderingSystem" requested by the login. The login failed. Login failed for user 'NT AUTHORITYNETWORK SERVICE'." The strange thing is, this code works perfectly If I use it in a Windows Forms application. Is it a problem with SQL server, IIS or my code?I'm using SQL Server 2005 (SP2) 32bit developer edition + IIS 6.0 + Visual Studio 2008 Pro all runnign on my Windows XP x64 PC. Thankyou
I have been successfully using SQL Server 2005 developer edition for a couple of months now. However, when I started Microsoft SQL Server Management Studio this morning I could not connect to the €œDatabase Engine€? (I€™m using Windows Authentication). I can still connect with the €œIntegration Services€? and €œAnalysis Services€? on the same server. The server running on my local machine, so there shouldn€™t be any problems with the network. I am also able to connect with it through ODBC, it just seems to be the Server Management Studio which can€™t connect, and it only has problems with the €œDatabase Engine.€? Any help would be appreciated.David

Hi everyone, i have already created posts about this problem and im aware theres millions of replys, but i still cant get this to work and its driving me mad. The posts i have seen i dont understand? Im using the standard ASPNETDB Database, i have never opened up SQL Server Management studio, although i do have the express edition. i have tried everything and i am totally stumped as to what to do. Heres my web.config. It works in VWD 2005 Express, but not in WWWROOT or on webserver? PLEASE PLEASE PLEASE Can someone help me!!!!!!!!!

I've got code that on my own machine (visual studio .net 2003 and iis and sql server all exist on this box) works great. I display my test page, which loads a dropdownlist on page_load. This works great on my own machine.
When I move the code to our dev environment. Web server and database servers on separate boxes. I get the error "Object reference not set to an instance of an object" when i try to open the connection to the database. I thought it had to do with permissions and I check all through sql server and everything looks great. I then thought it was the connection string. I still haven't ruled this out, but I wrote a quick vbscript app to attach to the database and try to pull a record. The vbscript worked fine. So, the code works fine on my computer, but not on the web server. The connection does work with vbscript, but through my asp.net web app I get the "object reference" error.
All code below...
ASP.NET webpage: private void Page_Load(object sender, System.EventArgs e) {
if( !IsPostBack ) { // Create a command object for the query string mySelectQuery = "select id from vw_abcd order by ID";
SqlCommand myCommand = new SqlCommand(mySelectQuery,sqlConnection1); sqlConnection1.Open();
Connection string on my machine: workstation id=wXXXXXX01;packet size=4096;user id=testuser;password=testpass;integrated security=SSPI;data source=wXXXXXX01;persist security info=False;initial catalog=TestDB"/>
Connection string on web server: network library=DBMSSOCN;data source=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;initial catalog=TestDB
vbscript: Dim connConnection, rstresultset strConnectionString = "driver={Sql Server};server=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;database=TestDB"

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

I am having a problem adding a new server or going into my previously registered servers. I was using Sql express and now using the full version of SQL 2005. When I try to coonect to a server, In the server type I choose Database EngineServer name I typed in LOCALHOSTSQLEXPRESS, no names show in the dropdown for server, leave use windows authentication selected. then hit the advanced button and change the network library to shared memory, hit test button and get this 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.

I have a perplexing problem. I've developed an ASP application for our internal business use. I'm getting ready to launch, but every once in a while the application can't connect to the database. The error I get is: 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) We (IT and I) turned off the remote connections and it still happens. I'm afraid of launching without understanding what causes this and gettign a fix. To get it working again, we restart IIS and it works fine. I used VWD 2005 Express and it's running on SQL Server 2005 Express. Thanks for any help you may have.Scott J.
Ok, I'm new to all this, so please keep that in mind. I've built my first asp.net site and it works fine locally, but isn't working after I upload it. The site was setup to utilize asp.net 3.5 framework automatically, but since the host uses 2.0.50727.42, I adjusted the site to utilize 2.0 framework (hopefully that worked ok). The host is running an SQL 2000 server, so maybe my problem has to do with that, since the error is saying SQL Server 2005 (which is what I have installed locally). If this is the problem, can I adjust the files in Visual Studio somehow to work with a SQL 2000 Server? Here's the error: An error has occurred while establishing a connection to the server.

Hi All,I've written an ASP.NET 2.0 app that is working perfectly on my local machine when using SQL Server Express 2005 as a data source. To connect to Express I'm adding a connectionString in my Web.config file:<add name="libInstruct" connectionString="Server=localhostSqlExpress;Database=theDatabase;Integrated Security=True;"providerName="System.Data.SqlClient"/> I'm trying to migrate this app to our SQL Server box for live production use. I have detached the database from SQL Server Express 2005 and attached it in the production SQL Server box. Our SQL admin has created a SQL server username and password (not Integrated Security). All I have done is change the connectionString in my Web.config file to: <add name="libInstruct" connectionString="Data Source=the server IP address;Initial Catalog=theDatabase;User Id=theUserID;Password=thePassword;"/> Are there steps in the process that I am missing? I'm getting an exception when I try to connect to the db - System.Data.SqlClient.SqlException: Login failed for user 'libInstructWriter'. Reason: The password of the account must be changed.Thanks for any help you can offer! Thom CoxMedford, MA
I`m new to posting to this group so please keep that in mind while I fumble through my explanation of my problem.
I am building an operational data store and have a staging server where I encountered the following sequence of events. I need help in getting back to square one.
- This server has Win NT 4.0, SQL Server 6.5 with service pack 4, and Informatica PowerMart 4.04 on it.
- While using PowerMart to transform some data either SQL Server or Informatica locked up and Informatica gave message it could not communicate with the server.
- I could not connect to server using SQL Enterprise Manager. Thinking that I might have run out of user connections I stopped the Informatica and SQL Server services and then restarted SQL Server in a minimal configuration mode. I used sp_configure/RECONFIGURE to increase the number of user connections and was then able to connect to the server but couldn`t do anything because I got a `not enough memory` error. Again, I used sp_configure/RECONFIGURE to increase memory.
- At this point, trying to connect to SQL Server with Enterprise Manager gave me a `cursor is not open` error. I couldn`t find anything about this error in Books On Line.
- Knowing that I had to re-install SQL Server eventually (wrong sort order) I attempted to remove SQL Server before re-installing. The removal process was interrupted and did not complete normally.
- I deleted the C:Mssql.. directory and then attempted to re-install SQL Server using the BackOffice installer. Installation seems to be fine until the very end where I get an error that it can not connect to SQL Server and it fails.
- I have no option to remove SQL Server and can not get past the failure to connect to server error at the end of the installation process so what options do I have to get SQL Server back?
I installed SQL Server 2005 with Windows Authentication. While attempting to connect via Visual Basic.NET or ASP.NET using connection string (given below), it displays following error:
Connection String: Data Source=MYLAPTOPRPK;Initial Catalog=testdb;Integrated Security=True
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
when i tried connecting to SQL Server Express I got this error, be it connecting via Windows Authentication or SQL Authentication. Pls see below for the error message:
===================================
Cannot connect to JOHNSONSQLEXPRESS.
