Web Forms :: Updating Database Name In Connection String In Web Config At Runtime
Feb 21, 2012
My problem is i need to update only the database name in current connection string in web.config at runtime....
this is the sample code .. to update connection string . but it updates the name of connection string  i need to change the database name of connection string !
public static void UpdateConnection(string name, string connString) {
var webConfig = new ExeConfigurationFileMap {
ExeConfigFilename = GlobalSettings.FullpathToRoot + "web.config" };
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 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?
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.
Does anyone has an idea on how to change the connection string of the webparts at runtime. i have a multitenant app, and would like to store each accounts users settings in their respective DB's i tried changing the connstring in the webpartsmanager init, and the page load event
Dim myConfiguration As System.Configuration.Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
in MyWeb there are all the aspx page and some entites datamodel, in MyApp there are the class with function like "getter data from DB" and there is a entity data model.
afeter the deploy, I have only the web.config and the connection string for the entity datamodel....itīs run ok, read/write the data on the DB.
The problem is with MyApp.....after the deploy it is a dll file and I donīt have the app.config and the entity inside it donīt run, not read/write nothing on the DB.
There arenīt error or messager but not read/write the data in the MyApp project.
all run on the iis 7
now...the question is:
I lose the connection string (in app.config) after the deploy?
Can I put a entity in the MyWeb and read it in another project (myApp)?
i have a dropdownlist contaning years..now i want to connect my database by dropdown selection.if i select 2013 it will connect 2013 database ,if i select 2014 it connect 2014 so on..
I want to encrypt my web config when i deploy it to server so that the username and password of database is secured. I've tried some of the encryption and it did'nt work. here is my code.Â
I added a database to my project. When I did so an app.config file was added to my project. (Yes I know I have dangerous info in the connection string. I shall change that but for now I am messing around with test stuff.)
I did a google search on how to get the connection string value and found. string sConn = ConfigurationSettings.AppSettings["ConnectionString"]; I am getting a warning that this is obsolete. It has been replaced by ConfigurationManager.AppSettings. Ok Fine. According to the docs, it is also in System.Confiuguration which I already have a using statement for above. But when I attempt to use it, it is not part of the assembly.
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?
