How can i get ConnectionString In web.Config when you are in DAL(data access layer)Some said it should me in <appSetting> but i think this is not appropriate to do because web.config have dedicate tag for connection strings.i am creating a 3 tier each layers is a project in 1 solution
Project ://solution
|_View :WebApp // Dependence (BLL,ENTITY )
|_BLL : ClassLib // Dependence (DAL,ENTITY )
|_DAL : ClassLib // Dependence (ENTITY )
|_ENTITY : ClassLib //note this is not a layes just a central data object reference
I have created a website (VB) on my local host. A couple of pages on this website use gridviews or detailsviews with an AccessDataSource connection to a MS Access database. This works perfectly. But now I want to move this website to a hosting provider. And on this hosting provider my website works well but not the pages with a connection to the Access database. I searched the whole internet for a solution but I didn't found it.
Folder structure on the host:
- db > Access databases (name: testdemo.mdb) - logs -wwwroot > website (for example, the gridview is placed on index.aspx).
I think AccessDataSource didn't work, but what kind of code may I use in the index.aspx and web.config? My hosting provider said only, use a direct link to the database and not a relative, for example: E:xxx.comdb estdemo.mdb
I 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:
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 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
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.

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.
I need help with changing this DSN to a DSN less var connection .whenever i use the dsnless connection i get an error since the String connTaftPrjPic is reused in the code.The Objective is to change to a DSN Less connection without affecting the connTaftPrjPic.
I have created a ASP.NET 4 application in VS 2010 using Silverlight and RIA Services.
After finishing the first release on my development pc, I'm starting some deployment testing in a server in my local network.
After sucessfully published the web application using the Visual Studio FTP publishing option, I notice two strange things:
1 - On the IIS properties of the website I have uploaded my files to, you can see now a connection string, named as LocalSqlServer that points to the aspnetdb.mdf database file. I had a look in the web.config file and I could not find this connection strind defined there. So, where is it located? Where did IIs got it from?
2 - As the aspnetdb.mdf file is not deployed withtin the web application and I a musing SQL express in my testing server, where can I drop the mdf and ldf files so they can be attached when the applicaiton runs? I know I can perform an attach operation using management studio,but I'm wandering where is the DataDirectory folder ASP.NET looks for to attach it at runtime?
i have done a project using ASP.NET and SQL database...and it's working good.but everytime i run the project in other computers i need to set connection path to database.without set connection how to run the project.using "App Path"? please let me how to set App Path in ASP.NET PROJECT.
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I am using a AccessDatasource for getting values from a accessdatabase for a Dropdown list. After i load the page and close it, a .ldb file is created. After wards i am not able to open the database manually. How to close the connection. I have given Network service Modify access [URL] to share permission, still no go.
In IIS 7 you can create database connection strings. I suppose this must be encrypted and best protected by IIS. This is nice, but how do I access it programmatically?
Somehow I deleted my App_Data folder and had to recreate it... it only had one database in it ... an Access Database. My .aspx pages that use the DB are giving permission errors when they load... I can't find anyplace in my DB or on my VWD Express where I can set the permissions (nor on my hosting service).
I'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?
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.
Seems one have to configure your connection a bit different in NHibernate configuration. In my web.config I'll have it like this (and it work):
Quote:
<add name="ApplicationServices" providerName="System.Data.SqlClient" connectionString="Data Source=72.118.116.71,1511;Initial Catalog=xxx;User Id=xxxx;Password=xxxx;" /> The sample I'm using (Trying to figure out NHibernate) configure a local database like this:
Code:
<property name="connection.connection_string"> server=.SQLExpress;database=NHibernateSample; Integrated Security=true; </property> I've been trying various variations of this and cant get it to work:
Right now, when I am copying the website to host server, I am changing the connection string in webconfig file and at each location of a sqldatasource or a query .. thats like more than 30 places where I am doing this.
When I am done copying the website, I have to change all the connection strings back to dev server for me to keep working on the dev copy....
I have an application 'A' builded by VS2005 and Framework 2.0.50727 before.And I am fixing an application 'B' builded by VS2003 with Framework 1.0, so I installed 1.0 yesterday.Everything worked fine but today when I was running 'B', it showed "Visual Studio cannot create or open the application because the Web server on this computer is not running. Start the Web serber before proceeding."Even if I reintall 1.0, VS2003 still shows this message.Then I closed VS2003 and open VS2005 to run application 'A' to see if app 'A' works fine.
But after I run app 'A', the IE says cannot display web page.So I checked my Default Web Site in IIS, it says 'The connection to the server was lost. Do you want to attempt to reconnect?'I tried solutions from internet to solve running app 'A' :1. Type C:WINDOWSMicrosoft.NETFrameworkv2.0.50727 -i or -u in command.2. Checked the World Wide Web Publishing status is startedThe running app 'A' still gave me cannot display IE picture.Does anyone know how can I do for it?
I have decrypted my connection string in web.config file of the application programatically. But after deployment under the ASP.net tab of application virtual directory when I click edit configuration the connection strings in web.config file are visible in decrypted format i.e readable form.
I have been preparing for a conversion of an old application to an ASP.NET webapplication at beginning of the year. Generally, the development version of the webapp will also be the webapp that goes into production. We here make "clones" of the database server, assign new name, etc, which is then used for development, training, and so on without any threat of changing data on the real db (sql server 2005). I know it is possible to have more then one connection string in the web.config. My question centers around if there is a simple method for allow multiple connection strings and pick the one that is to be used for dev, production, training, and so on? I originally thought about constructing some type of admin form that the connection string can be selected from.
I have an app that is a bit old and will eventiall be rewritten but until I get the time it needs to continue to be patched. THe app is desgined broken into three layers (Web, DAL, BLL) The web site uses the DAL.DLL and BLL.DLL and the Website has some dataaccess and the sonnection string is saved in the web.config. For the DAL it is stored in the app.settings. Is there a way for the DAL to use the connection string that is stored in the Web.config even thought it is in DLL for the production site?
