Connecting To SQL Database

Apr 25, 2006

Hi all,
 

Please help me with the following problem because I am running around in circles.

 

I have this problem getting a forum online.

Since it is a database related problem which I have been trying to solve at the ClubSite forum I am taking the liberty to come to this forum with this problem.

 

This is the story:

I have this separate SQL database dotForum2004.mdf in App_data.

After trial and error got it working locally.

 

But when I put it online at my webserver (On a Stand-alone PC at my jobsite) I get an application error.(From the Club Site application)

 

This is the connection key which works fine locally. Is there something obvious you can point me at?

 

<
add

key
=
"
forumDSN"

value
="
Provider=SQLOLEDB; Server=.SQLExpress;AttachDbFilename=|DataDirectory|dotForum2004.mdf;Trusted_Connection=Yes;"
/>

 

Thanks in advance,

Lex

Right Code Statements Of SqlConnection &&amp; ConnectionString For Connecting A Database In Database Explorer Of VB 2005 Express?

Feb 14, 2008

Hi all,

In the VB 2005 Express, I can get the SqlConnection and ConnectionString of a Database "shcDB" in the Object Explorer of SQL Server Management Studio Express (SSMSE) by the following set of code:
///--CallshcSpAdoNetVB2005.vb--////

Imports System.Data

Imports System.Data.SqlClient

Imports System.Data.SqlTypes

Public Class Form1

Public Sub InsertNewFriend()

Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=shcDB;Integrated Security=SSPI;"

Dim connection As SqlConnection = New SqlConnection(connectionString)

Try

connection.Open()

Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)

command.CommandType = CommandType.StoredProcedure
.......................................
etc.
///////////////////////////////////////////////////////
If the Database "shcDB" and the Stored Procedure "sp_inertNewRecord" are in the Database Explorer of VB 2005 Express, I plan to use "Data Source=local" in the following code statements to get the SqlConnection and ConnectionString:
.........................
........................

Dim connectionString As String = "Data Source=local;Initial Catalog=shcDB;Integrated Security=SSPI;"

Dim connection As SqlConnection = New SqlConnection(connectionString)

Try

connection.Open()

Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)

command.CommandType = CommandType.StoredProcedure
........................
etc.

Is the "Data Source=local" statement right for this case? If not, what is the right code statement for my case?

Please help and advise.

Thanks,
Scott Chang

Connecting To A Database Twice Fails Because Database Is Uses By An Other Process

Apr 23, 2008

 Hi all,I come up with a problem aleady discussed in some posts especially in the post http://forums.asp.net/t/1235761.aspx. but I got in not finally solved.The main problem is connecting to a database twice which causes errors. So I think this might be the right place to ask my questions.  Here ist the problem in short:I'm using VWD on XP-Professional with SQL-Server Express and Reporting Services Express. All with Windwos Integrated Security and User Instance (SQLExpress). In my web-application I had for all Datasources the connect string:Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydatabase.mdf;Integrated Security=True;User Instance=True This works fine so far. I also have Reports designed with the Report designer using the same connection string. I can preview the reports and I deployd thre reports successfully. I want to call these report using a report viewer web control.Now the problem:when I call the remote remote report from my web-application, the database cannot be opened because an other process is using the database (see post mentioned above). It seems that this is a problem with attaching the database twice: from the sql-server and from the report-server.So I used now a new connection string without "attaching" the database (in vwd and in report designer):Data Source=.SQLExpress;Initial Catalog=C:inetpubwwwrootmyappAPP_DATAmydatabase;Integrated Security=True Now everything works...but ... only on my machine. On the production machine this does not work. I wonder anyway, why its working on my machine, because I never "attach" the database (there is no connection string with  AttachDbFilename and I have not opend the developer and have not opened the sql management studio).On the production machine the concurrent (SQL-Server and Report-Server) connection to database does not work with either connection strings, no matter if i attach the database with sql server manager or not).This all drives me crazy for days now. All I want is to use SQL-server and Reporting- Services with its nice features and not repairing my tools. I thought I have a standard Installation, nothing special, but the standard obviously makes problems.Here finally my question:Does this environment ( web-application with remote reports) with Express edition cause normally no problems?Can I "attach" a database only once?  How should I connect with my web application that uses the sql-server connections and also  the report-server-connections (attaching twice does not work).What connection strings to use and when (AttachDbFilename or Initial Catalog).Are these problems specific to the Express Editions? I thank you in advance for any help  Dieter

Connecting To SQL Database?

Sep 24, 2007

I am very new to web development using Microsoft Visual Studio.  (my primary expertise is Framemaker 2003).  I am currently going through your ASP.NET 2.0 videos and reproducing the lesson content on my development system.  I have Microsoft Visual Studio 2005 Professional Edition.  I also have Microsoft SQL Server 2005, Microsoft SQL Server 2000, Microsoft .NET Framework SDK v1.1 and Microsoft .NET Framework SDK v2.0.
I seem to be having difficulties with the SQL interface because when I try to use the Property object from Lesson04, I get System.Web.HttpExceptioon {"Unable to connect to SQL Server database."}.  When I subsequently tried to Add New Item - SQL Database from Lesson08, I get a Microsoft Visual Studio error box "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly.  Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251"
Any ideas?  I know the videos are based on use of the Microsoft Visual Studio Express -- are there significant configuration differences between it and Microsoft Visual Studio Professional that would make these lessons incompatible?

Connecting To Database Using VB

Jun 19, 2008

I am new to the visual web development program; however, I have created many applications using Visual Studio Express in Visual Basic.  I am trying to figure out how to:1.  Define a connection string in VB2.  Open a current Connection3.  Define a SqlStatement4.  Retrieve the information5.  Display results in textboxI am basically trying to get a login system set up so that a user can type in his name and password and is then directed to a secure page.When I create a new application and want to do this I would use the following code: Dim cnUsers As New SqlClient.SqlconnectionDim cnUsersString As String = "CONNECTION STRING"Dim UserCommand As NEw SqlClient.SqlCommand = "Select chrUsers, chrPassword FROM tblUsers WHERE chrUsers = '" & txtUserName.Text & "' AND chrPassword = '" & txtPassword.Text & "'" cnUsers.ConnectionString = cbUsersStringcnUsers.Open()UserCommand.Connection = cnUserstxtResults.Text = cnUsers.ExecuteNonQuery()cnUsers.Close() That is a very rough draft of what I would code it as.  If you have any suggestions please let me know! - NUStudent-

I Need Help With Connecting To A SQL Database...

May 2, 2007

For an assignment at school, I need to build an ASPX web page that looks up books in a database. This entails the use of a SQL database, and I am having issues trying to connect to the database.

here is a pic of the error I am getting:



I am using Visual WebDeveloper 2005 Express to do this in, and I can't find any options that pertain to the error above. I looked in the SQL configuration tools that I have installed, and I can't seem to find the correct options that I need.

Does anyone know how to resolve this? If you can provide direction on this, that would be great.

Help Connecting To SQL Database

May 2, 2004

Hi. I'm totally new here, and I'm not an expert when it comes to SQL, so bear with me. This is my dilemma:

I use Access 2000 to connect to my Microsoft SQL Server 2000 database. Recently, our provider switched us from a shared server to a dedicated server. The site is up and running perfectly, but I can't connect to my database via Access anymore. Once I received the new location of the database, I ran odbcad32.exe and configured the database's DSN info where appropriate. I run the "Test Data Source..." function and the tests are seemingly successful. When I open my database using Access, I'm able to log in successfully, but when I click on any one of my linked tables, I get the following error:

Could not execute query; could not find linked table.

[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name
'NAMEOFDATABASE.NAMEOFTABLE'. (#208)

The support team at my provider are not exactly geniuses, so who knows if and when they'll be getting back to me. In the meantime, does anyone have a clue what might be causing this? Since the site is working perfectly, I assume the connection strings are okay and the database is perfectly intact (I even checked to see that the most recent entries were live), so what gives? If there's any more info I can provide, let me know. Thanks in advance.

Connecting To Database With C#

Jun 2, 2008

Hi, I will post this on a c# forum as well but maybe someone has an answer here.

I want to connect to my database in a program i am coding with C#.
I have 3 databases in my SQL server (DB1, DB2, DB3)(perhaps schemas is the word to use) all under a connection called TEST (as opposed to SQLEXPRESS.

My connection string in my code is as follows:
string ConnectionString = "Data Source=.\TEST;Integrated Security=True;Connect Timeout=30;User Instance=True;";

My app reports a valid connection is made. WooHoo.
But,
When i try to do a select statement eg: Select * from DB1.Customers
I get the following error.
System.Data.SqlClient.SqlException: Invalid object name 'DB1.Customers'

I have tried removing the DB1. part from the select statement and specifying Database = DB1 in my connection string but that doesnt work either.

Any help provided would be greatly appreciated.

Thanks.

Help With Connecting To SQL Database And Binding

Jun 30, 2006

I am new to .net and I am using Visual Web Developer 2005 Express with SQL Server 2005 Express.  What I would like to do is connect to my SQL database (which resides in the app_data folder) and open a table and pull out a field and place it in either a textbox or label on the page. No editing or deleting. Just simple one field binding.  By the way, I can do this with all the cool built-in tools of VWD, but I want to know how to do it all by hand.  I would really appreciate it if someone could help me out.

Having Trouble Connecting To Database

Aug 19, 2006

Hi I am new at this.   
I have a little program written in C# in asp.net.  The program basically accesses a database and stores new records.  The database is supposedly already attached to MSDE so I am able to see the tables of the database inside asp.net.   I can click on the individual slots of the table and modify the datas manually.  However, I want to connect to the database from my C# program and be able to input data into the database via the website that the C# program produces.  After I type in the data into the website and click the submit button on the website, I get an error page that says this:
Login failed for user 'sa'
the line of code thats causing this error is:
con = new SqlConnection("data source=(local)\NetSdk; initial catalog=Friends; user id=sa");
Why is it not able to connect to the database?

Having Some Trouble Connecting To A Database....

Feb 13, 2007

I am doing one of the Microsoft virtual labs "Creating ASP.NET Web Applications with C# - Part 2" using Visual Web Developer Express. I am trying to fill a gridview with database information, but it gives me the 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)".This is on the local machine that I am executing the code.  public void BindGrid(string sortfield)

SqlDataAdapter myCommand = new SqlDataAdapter("select * from Products", myConnection);
//Create dataset and fill it with Product data

Source.Sort = sortfield;

dgProducts.DataBind();
} It stops on the line "myCommand.Fill(ds, "Products"); and points out the error mentioned earlier. I am not sure what to do...any help would be greatly appreciated, thanks in advance, and I apologize as well if I have not pointed out enough information.

2 Errors When Connecting To Database!

Sep 7, 2007

Hi,
 I uploaded my website to a server and I face some problem to connect with the data base
In the website I have one databse that combaine the asp.net membership and roles tabels
when I try to login the website I got 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. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I use the login control
+++
another error I get it when I request data from tables other than the member ship and roles tables,
the error is
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate's CN name does not match the passed value.)
 
maybe the second error related to the first becouse in the second stuation I also request the userName wich comes from the membership's table
 
Please, advise me to solve these problems

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.

Having Problems Connecting My Database.

Dec 27, 2007

Hi I was working on a project that I had to stop a couple months ago since schooling got in the way and I had no time to continue. I finally have time now and I am just resetting up everything however I keep getting this error everytime my website trys to access the database. "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)" I am not sure why this is happening. What has changed since my last time working on the project New computerFormat and windows reinstalledWent from vs 2005 to vs 2008Went from sql express to sql serverProject file is on a new partition with different drive letter.My database is located in my app_data folder. I am able to connect to the database. I have gone to the web.config file and changed the connection string to point to the new location of the file. I notice when I attack my database to sql server its name is  H:WEBSITEJAPANESEAPP_DATAJAPANESE.MDF what is the old location the new location is G:WEBSITEJAPANESEAPP_DATAJAPANESE.MDF so I am not sure if this is the cause of it or what(but it won't let me change this name). Thanks

Connecting Database To Asp.net Pages!

Jun 3, 2008

Hello,
Iam a new developer to asp.net, I have been trying to connect a database to a asp.net page but many times i failed. actually  i dont want to connect just directly by dragging and dropping controls rather i wanted to bind controls like textboxes and comboboxes but at first i think i have to make querystrings to and sqlconnection to connect to the database. I mean i have to manually code all these items to get my pages connected. but most of the time i face the bug which is:
Server Error in '/WebSite2' Application.


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)
is that because of the fact that i dont sql server management studio installed actually i tried the same process with some other pcs that does not have sql server insatlled but it was working pretty well, but now i dont have a sql server installed  and the problem still insists.
hope i have clarified my problem, sorry if it is a bit lenghty
thanks and regards

Error Connecting To Database?

Sep 7, 2005

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

Syntax For Connecting To SQL Database

Sep 29, 2005

Can someone tell me if this is the correct syntax for connecting to a
sql database thats on  a server differnt then the application.
(vb - web config file)
<connectionStrings>

    <add name="MyDbConn"
        
connectionString="server=24.243.45.23;user
id=Admin;password=jkjd;database='test';"
         providerName="System.Data.SqlClient" />
  </connectionStrings>

It works when I use localhost instead of the ip but I need to access an
sql database on another server and it doenst connect. It may not be my
code but I wanted to clarify before I spend to much time messing with
my sql settings.  Thanks

Can Anyone Help Me With Connecting To A Database To Search?

Mar 22, 2006

I'm trying to make this piece of code work, I get all of it except how I get the data from the database, what I wish to do is. On page load I wish to take the value of a querystring in the page URL called ProductID and search a database to see if it exists in a specifical table and column, if it exists I wish to make a button not visible. the code I am using is:
 
#############
 
protected void Page_Load(object sender, EventArgs e)
    {
// Get the querystring value
        String inQueryString = Request.QueryString["ProductID"];
       
        // Get the data from the database, using the above value
        DataTable data = ??
  
The datasource I want to connect to is SqlDataSource1, and the table I want to search is “Reviewsâ€?. I want to search in the column “ProductIDâ€? and search for the ProductID from the URL query string above.
       
        // Did we find a product in the database?
        if (data != null &&
            data.Rows.count > 0)
        {
            // Code to display the product's information
           // We found a product, so we need to hide a button
            Button5.Visible = false;
        }
       
   
        }
 
##########################
 
Please can somebody fill in the missing bit for me so i know how it should be, i've searched the quickstart tutorial on the menu above and I still don't understand it, as it doesn't show anything like what I want to do, and I have looked at numerous websites about the matter. If you don't have time that is okay, but If somebody does have the time to show me what I need, I would be very greatfull.
 
Regards

Connecting To Remote Database Using EM

Apr 18, 2006

Hi to all:
I always had a problem connecting to SQL Server from home using EM.
I do add a new server registration, but i always get the following exception:

A Connection could not be established to IP ADDRESS
Reason: SQL Server does not exist or access denied.
ConnectionOpen(Connect())
At the same time, I do use a utility, found at http://sql.bhaidar.net to connect to the same database and works perfect.
Is there any configuration I should do to my pc, don't know maybe some port configuration or so, to allow EM to connect to those remote databases?
Thanks in advance.
Regards

Connecting To Table In Another Database In SP

Aug 3, 2001

I have a stored procedure that looks at certain tables, but now one of those tables has been moved to another database by our DBA. Being that the database is on the same server, is it possible to do a three part statement like this in the SP:

DB2.DB2Table.DB2TableField

I don't to add another database connection to my ASP page because when I have before it causes a "Multiple Step OLE DB" error.

TIA,

John Wilson
