I need a connection string to connect the microsoft 2003 database with my ASP.NET webserviceWhen just making a website I used to use the following connection statement
OleDbConnection dbconn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" + + Server.MapPath("~/db/SalesCentral.mdb"));
Now as I am using a webservice the Server.MapPath function is giving an error
I have a database on Go Daddy and my VS2008 app can not access it via web.config connection string. Of course runs great locally in development. I copy/pasted the connection string information from Go Daddy exactly into my web.config file. Web site runs fine on the web but when I try to Login at my login page, i get :The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.
I used VS2008 to create the .sql script files and uploaded them to Go Daddy and the Go Daddy people say everything works as they and I can both Login to the database from within GoDaddy.The database i am trying to access consists of the a ASPNETDB.mdf and another Database.mdf together as one in the Go Daddy database.
here is what i used: <connectionStrings><add
name="superskin"
connectionString="Data

i have made a project that has an access database.
i have manage to connect and retrive data from the database at aspx and at code behind.
the problem is that i do not want to write the connection string at code behind again and again but to get it from the web.config as i am doing to the aspx pages.
this is what i do at aspx pages:
<add name="dataConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|data.mdb;Jet OLEDB:Database Password=data
@123" providerName="System.Data.OleDb"/>

I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?
View 1 RepliesI have a Windows Service I have developed in Visual Studio 2005 (C#).
It accesses a database using a connection string in machine.config.
On my Windows XP Pro 32bit (SP3) machine, it works correctly.
On my new Windows 7 Pro 64bit machine, it throws "object not set to an instance of an object" when it gets to the line where it's trying use the connection string.
This is the 'object' which is not set in Windows 7:
ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString
The machine.config has the same connection string set up on both machines.
A .Net 2 website transferred to the Windows 7 machine has no problem accessing the same connection string.
I have tried a bunch of different permissions on the machine.config and its containing folders, and setting the service to log in as Admin, but I don't know exactly what permissions are required.

I know that most people store the Database connection string inside the web.config file.
But my question is if we move the web.config file from dev to prod then we have to change the connection everytime.
how can we have a connection string that we do not have to change when we move our code from dev to prod.

I'm having a terrible time being able to connect my access database to my website. I'm using 1and1.com as my host. The database resides in my App_Data folder. I checked everything I could think of on the host side. I cannot query from the database through VWD Express nor create a typed dataset .xsd that will allow quering the database.p.s. - I don't need any sophisticated security on the database, just a homegrown sign in I put together that works fine for my site which is mostly xml file data.
View 10 RepliesI've got an ASP.NET web project which connect to an SQL Server 2005 DataBase.I think that I'm doing the part of the database connection awfull because everytime I need to do a query (select for example) I'm creating a new connection, opening the connection, creating the command, executing the query, using the results and closing the connection.
Is the rigth way to open a connection in the start of the application and closing at the end?? How can I do that?? I'm retrieving data but what will happen to database server when the application will be used by many people?
To give some background details, I have created a website for a friend that has a few pages that require a database in the background. I've used Visual Studio templates for most of it, so there's the standard ASPNETDB.MDF file that's created for users and groups, a login page and a page to view and manage those users etc etc. The login page uses the standard controls for logging in, retrieving lost passwords and so on. Being standard controls, by default they get the connection string from the web.config file. Upon attempting to upload the site to my host (1and1.co.uk in case anyone else has any dealings with them) I discovered that storing the connectionstring doesn't work. 1and1 support say that the sql databases can only be accessed using scripts like this (this is an example of theirs):
<html>
<title>Queries from the MS-SQL database with ASP</title>
<body bgcolor="FFFFFF">
<h2>Query from table <b>products</b> with ASP</h2>
<%
Set conn = Server.CreateObject("ADODB.Connection")
conn.open "PROVIDER=SQLOLEDB;DATA SOURCE=mssqxxx.1and1.com;UID=dboxxxxxxxxx;PWD=xxxxxxxx;DATABASE=dbxxxxxxxxx"
'This code block will create a recordset
Set rs = Server.CreateObject("ADODB.Recordset")
SQL = "select * from products"
rs.open SQL, conn
'will iterate to display the records got from the database
While Not rs.EOF
response.write(rs("id") & " " & rs("price"))
rs.MoveNext
Wend
'closes the connection
rs.close
conn.close
Set rs = Nothing
Set conn = Nothing
%>
</body>
</html>
So my question, is it possible to get the standard asp.net controls to access a database through a script like this?
I have this following requirement.
My Web Application is hosted on Server A. My Database is hosted on Server B.
Server A and Server B are not on same network. How can i point my connection string to the database in this scenario? Can any one give an example for this kind of Connection String?
I'm working on an application that is connected to the online MSSQL database and everything is working fine.The model I'm using is entity model.The problem is that I have to change the connection string from the online database to the local one,but I don't know how.Creating new model isn't an option.I tried changing the connection string in web.config,but errors are the only thing I get.
This is what I have in web.config:
<connectionStrings>
<add name="PravosudnaAkademijaEntities" connectionString="metadata=res://*
PrakModel.csdl|res://*/PrakModel.ssdl|res://*/PrakModel.msl;provider=System.Data.SqlClient;provider connection string='Data Source=HRVOJE-PC;Initial Catalog=pak_baza;Integrated Security=True" providerName="System.Data.EntityClient" />
What will change in connection string after upload database to hosting?
