Hey everyone, I'm having trouble connecting to my sql express instance through my vb.net application. I can connect to it from Visual Studio and the management tools, but get an error when connection with a connection string. What should my connection string look like? I'm using the a default SQLEXPRESS instance.
View 3 RepliesAll,
I'm a newbie here so forgive me if I have missed something completely obvious.
I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />
What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me 127.0.0.1, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
<add key="DBName" value="Database name" />
<add key="DBServer" value="127.0.0.1" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as 192.168.2.2 active yes enabled yes, and IP2 as 127.0.0.1 active yes and enables yes, I have tried the 192.168.2.2 and this gives the same errors, this is my registed IP on my home network.
I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.

Here is the situation:
I have SQL server express 2005 installed on my pc as instance SQLEXPRESS.
I have created a Visual Basic applicaion with the following as connection to the SQL server express 2005 running on the same PC:
****************************************************************************************************
Dim lconnectionString As String Dim builder As New SqlConnectionStringBuilder Dim cmd As New SqlCommand Dim reader As SqlDataReader Dim parameter As SqlParameter builder("Data Source") = ".SQLEXPRESS" builder("Initial Catalog") = "" builder("AttachDbFilename") = "C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf" builder("Integrated Security") = True builder("User Instance") = True lconnectionString = builder.ConnectionString Dim sqlConnection1 As New SqlConnection(lconnectionString) cmd.CommandText = "SP_add_collection" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = sqlConnection1 sqlConnection1.Open()
*******************************************************************************************************************
It seems that i can not connect to the abc.mdf in SSMSE while the VB program is running. (ERROR:
Database 'C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. (.Net SqlClient Data Provider) )
If i connect to the abc.mdf first in SSMSE, then run the VB program afterwards, it gives me the error on this line -- sqlConnection1.Open()
I want to be able to access the abc.mdf database with both SSMSE and VB at the same time. Could anyone help me on this ?
Thanks very much !

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?
Hello,
For my application, I need to consult a database located on a server on the local network. The application is located on my pc. I use the connection string
Code:
"Integrated Security = SSPI;database=dbName;data source=serverName"
(I program in C# and connect with ADO.NET)
When I compile my project as a windows application, this works fine. But when I compile as a web application in ASP.NET and try the same connection, it won't connect. How can this be solved?
Thanks
Hi guys.
We have an external webserver(server1 on domain1) is a DMZ, and sql server7(server2 on domain2) inside the firewall.
Domain1 trusts domain2 but domain2 does not trust domain1.
Our firewall hosting by outside vendor and they told me they already opened up the port 1433 for server2.
I put a small asp.net application on server1(this application works fine in intranet. 2000 server,iis5,virtue directory, and .net frameword were well installed and configured), and I got S'QL server does not exist or login fail error'.
Any idea about that? And how to test the port was opened?
Any input appreciated.....
Hi
I developped an ASP.Net application (with Web Dev Express ) wich attempt to connect to SQL Server Express (installed in the local machine) using Windows authentication.When i launch my application within Web Dev or from IE navigator i receive the following error message : Cannot open the database 'MyDB' login failed for user ServerNameASPNet.I use SQL Server Management Studio Express to give the user ServerNameAspNet permission to connet to the database but i still receive the same error message.I created a user with strong password within Management Studio with connect permission and attempt to connect from my application using SQL Server authentication i receive the error message : The user 'UserName' is not associated with a trusted connection for SQL Server.Note that when i use the Connect to Database tool in Visual web dev the connection success when i use Windows authentication but fails when i use SQL Server authentication with the same error message above.My OS is WXP Pro SP2

I added a database named appdata to the app_data folder to hold temporary application data. I want to show this data in a report. I created a dataset and an object to select the data. I then created an report.fdlc and a report.aspx with a ReportViewer on it pointing to the dataset object. If I right click on the report.aspx and View in Browser, it work perfectly. But when I upload it to the server I get and browse to it I get (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified). The server does allow remote connections. So I am thinking it's my connection string of the fact that the server doesn't have Sql Server Express.?
Here's my connection string. What am I missing here?
<add name="appdataConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|appdata.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
I am having a strange problem. I have an application that to connects to SQL Database in SQL Server 2005.
When I run the application with Visual Studio everything works fine but when I deploy the application on my web server and then to access the site .
I get an error : Login failed for user ''. The user is not associated with a trusted SQL Server connection.
For some reason the application is not passing the user name . I have checked the IIS and authentication is set to Integrated Windows Authentication .
My connection string is correct as well
<add name="xxxxx" connectionString="Data Source=xxxxxx;Initial Catalog=xxxx;Integrated Security=SSPI" providerName="System.Data.SqlClient"/>
I will appreciate any kind of assistance in this matter. Thanks
Hi!I am going to connect to "SQL Server 2000" through an "ASP.NET Web Application". My development environment is "Visual Studio .NET 2003". In my "Toolbox" -> "Data", I drag a "SqlConnection" and drop on the page. It would automatically be named "SqlConnection1". In its "Properties" -> "ConnectionString" -> "<New Connection...>", I would enter my Server Name (SAMIEI), select "Use Windows NT Integrated Security" and Select the Database on the Server (Northwind). Then such Connection String would automatically be generated:
"workstation id=SAMIEI;packet size=4096;integrated security=SSPI;data source=SAMIEI;persist security info=False;initial catalog=Northwind"
Now, I may see "SAMIEI.Northwind.dbo" in the "Data Connections" row of "Server Explorer" with its all "Database Diagrams", "Tables", "Views", "Stored Procedures" and "Functions".Please take a look at the following code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try SqlConnection1.Open() Catch ex As SqlException Response.Write(ex.Message) End Try
End Sub
It would unexceptedly encounter such error:
"Login failed for user 'NT AUTHORITYNETWORK SERVICE'"
Please tell me the reason. I am much obliged to you for your attention.

Hi
I can't connect to sql server 2005 from my asp.net web page. I seem to be able to connect to it when i run the application from within visual studio but i can't connect to it when i run the application from IIS.I am new to sql server 2005 express so please bear with me.The error message i get is: Cannot open database "Vets" requested by the login. The login failed.Login failed for user 'OSCAR2K4ASPNET'.I don't know where this user OSCAR2K4ASPNET came from but i looked in sql server 2005 and there he is. In the left hand pane I went to Security and then logins and found oscar2k4asp.net there. I went to the properties for this user and went to User Mappings. There was no tick next to my Vets database so I added one and ran the application from IIS. I also added the user to every single role in the vets database (including dbowner). I also went into the vets database itself and found the oscar/aspnet user and made sure he was added to every role.
I ran the application again. This time i got a lots of different errors. If the page was trying to run a select procedure I got the error user does not have select permission. If the page was running an SP i got the error or user does not execute permission
I have never had this problem before so I don't understand.Where did this user come from? Was he created automatically when i configured my database for membership and roles? How do i set up this user so he can access the databsae from IIS.
The only way I could get the application to run from IIS was to go to Security - Logins for sql server and add the oscar2k4asp.net user to the sysadmin role.
I find this very strange. Naturally i don't want to leave oscar2k4 in sysadmin.
Please help :) I can't upload my website until i fix this

We recently installed Sql 2005 server and it was working fine. But today one of our user reported that they could not able to connect the sql server 2005 from the application.

OK, I am not a programmer, but administrate the Report Server and its security. The .NET programmers want to connect direct to Report Server using WEB.CONFIG settings (see below).
<appSettings>
<add key="ConnectionString" value="Server=bpatlqddwatlqddw01;Database=MP2_NET_STAGE;Integrated Security=False;User ID=MP2_Net;Password=xxxxx;Persist Security Info=false"/>
<add key="LogPath" value="\bpga030wde01wwwroot$MP2_NetLogs"/>
<add key="Url" value="http://bpga030wde01/MP2_Net/" />
What do I need to do to ensure their dynamic reports can run against my Report Server? What kind of rights do I assign the "MP2_Net" (above) login? All of this is outside the IIS-Report Server security environment? Do I assign rights via SQL Mgr? I cannot find any doco on this process.
Hi all,
I'm working on a project where I have to create a password protected form for teachers to submit reports about students.
Originally I was going to use asp.net to create the form, but unfortunately the server I'm working with will not be granted asp functionality in the allotted timeframe.
To solve this issue I have another idea. So I will ask a few questions to help with research before I begin coding.
Is it possible to create a windows application that can connect to an access database hosted online? The windows app will need to be be able to update, insert, and select information from the database.
There is only going to be about 30-40 people using this windows application once or twice a week.
Thus I envision taking a password protected access database and dropping it onto a server.
The windows application will have the online location of the database embeded into the code. (connection string)
From there on out coding for the windows application should be the exact same as if the database was hosted locally on the computer, correct?
Also,
1. What is a good way to check and make sure the computer is connected to the internet before my application tries to access the database?
2. Are there any drastic security issues with this process that I should think about. The database will only be password proected, and the windows application will take a username/password from the user and check it against a table before they are able to submit info to the database.
I just need to be pointed in the right direction for this project.
Thanks.
Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.
I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.
Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?
Thanks in advance for any input.

Connecting to a Microsoft SQL Server Database Using ASP/ADO
I have problem connecting to a SQL 2000 server that is hosted on a Windows 2003 server. My application uses classic ASP with VB6 components. VB6 components connect to SQL server and return data to ASP application. Everything was working fine when the application and SQL server was hosted on NT machine. Recently we have shifted to Windows 2003 server. Since then we could not establish connection to SQL2000.
I'm using UDL as connection string.
IIS and SQL2000 hosted on the same machine with Windows 2003 OS.
This seems to be a security issue. Earlier I faced this issue for a .net application which I resloved adding a domain account to both SQL server and IIS directory security.
Request your input to solve this problem.

Hi!
I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:
Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".
An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.
I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:
Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.
Any ideas to solve this?
Thanks

I have created a Web application that uses a SQL Express file Database (mdf). I have also created a console application that looks to the (mdf) in the Web Directory to process some server-side tasks, (Email, process data, etc). Everything works well on my Development Machine, however when I Publish my Web App and Console application to a server, the Web App works fine, the Console App is buggy. The main error I get is ;that the user logged into the server cannot access the Database. (User domcholman cannot access). However this is not always the case, sometimes it works.
Question is, how does SQL Express authenticate credentials when in Windows Auth mode? Shouldn't it allow the Service account to access the database? Are there any best practices? Should I use an account and password instead? thanks...
I have a small ASP.Net application developed in VS 2005 that I would like to deploy with SQL Express.
I have included the MDF file in the Application and added SQL Express as a pre-requisite for the Setup and Deployment project.
It installs SQL Express but when it tries to connect I receive:
"This is not a valid login Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITYSYSTEM'."
I don't seem to have any options using the "prerequisite options in VS 2005 in terms of command line deployment parameters.
Likewise I would prefer to attach the database to the instance (because I need to write a connection string from a PDA using RDA and I have zero clue how to do RDA directly back to the file).
Thanks for any help!

Hi,
I'd like to get the experts' advice on whether SQL server 2005 Express edition (SSE) is suitable for medium scale web applications.
I have looked through the reviews of SSE. From what I understand, its limitations over the MSSQL 2005 Standard are:
1. SSE limits database size to 4GB and memory to 1GB.
2. Support for only 1 CPU.
3. No analysis or reporting services.
4. No full text indexing
5. No SQL Agent.
I have a web application that is currently running on a shared web host with a shared MSSQL 2000 database. I'm thinking of shifting to a Virtual Private Server, where I can install SSE for free.
Currently my app has about 14,000 page views a month, and each of them pulls out data from the database. I don't use any analysis or reporting services, or full text indexing or SQL Agent (for now).
My questions:
1. Is 1GB memory sufficient for this type of application?
2. Is there any reason I should not be using SSE for my type of application?
Thanks in advance for the help.
