Change Connection String Saved In My.Settings In Program?
Jan 30, 2012
I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String. Being a setting with an unchangable 'Application' scope i cannot change its value at runtime.
The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ?

I'm trying to give my users the option to move their database to a different location, currently the datasource is set as an (Application Connection String) in the Project Settings, I know that when the scope is set to "Application" it cannot be modified but I'd like to know if there's a way for me to edit the location through code of my database in the application settings without crashing the program, can this be done? The purpose is to give whoever uses my application the freedom to choose where the database should be.

This is regarding a windows app in Visual Studio 2005, a VB Windows application.'ve stored a connection string called strSQLConn in My.Settings. I'm trying to change the Server in code. I set a string variable called strConn to a new Connection string. My.Settings.Profile2006sql = strConn
This produces an error saying that My.Settings is readonly. I'm missing something basic here.
I don't know if this is the best way to change a connection string to toggle between a development server and a production server. My understanding is that if the setting Connection string is changed it will be used as the default for all the table adapters in a strongly typed dataset. Is that the case?

I've always used this approach while implementing data layer DLL for web application:
1) put datasets into the dll project
2) use a helper class with a method like this:
public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub
3) when I need to use the dll I call a method like this (usually into global.asax):
xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")
This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

I am storing my connection string in my app.config file. I am using sql server express 2005. The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting. This is quite a pain.also I have now published my app to an ftp folder so that the clients can get the updates each time I make changes. saves me the hassle of going to them each time i update. so now i need it to be so that I won't have to change the setting all the time.Would the best way be to store the connection string in a settings table in the database?

We have a VBScript that launches an Access app that connects via ODBC to SQL Server - wouldn't you know the server name is changing.
Is it possible to use VBScript to modify the ODBC information in the registry to point to the new server? Basically changing one specific value for one specific key. Am I better off deleteing the ODBC key and readding it from scratch?

I want to change my class library's settings from an another program. For this, I've made a Public property in my class library. It worked right. But this is not my question. I wonder this is a right method? Can I access a class library's settings (My Namespace) from other project directly?

I'm writing a windows form application using vs2008. I need to connect to different SQL server express database files during runtime. There is a "how to do" video showing a technique for this
[Code]...
and then in the Form1_load sub and before calling the data adapter to fill data, insert codes below:
Dim strConnectingSting = NewConnectionString
My.Settings.RunTimeConnectionString = strConnectingSting
The method works but only for the first database. I found once adapter.fill is called and the connection to a database is established, the connection can't be changed.To do what I want, I have to create a startup project to call my main project. When I want to change connection, close the main project and start again.

I have developed a windows form application using VB.Net with data access layer using LINQ-SQL. I want to allow the database to be configured from the application. I have created a form for input and save the input details in an XML file.
I need to know how to configure the LINQ to start using the new configured database on startup. I have read in one of the threads here about dynamic allocating the connection string with the following solution to include in every file where the data context is instantiated. [code]...

I have created a very simple Visual Studio .net 2002 VB# program. It consists of form1 containing a DataGrid bound to an Access 2007 Database using OleDbConnection1, OleDbDataAdapter1 and DataSet11.The location address of the Database will change based on the user so, I need to make the connection string variable. Problem is inserting the following string variable "source=" & strFileLocation & ";" creates a fatal error

I am using vb.net and SQL server 2005 I have a project with database classes which are generated from database objects. That is I add a dataset to the project and drag and drop a database object onto it. The problem with this is that I have to give a connectionstring which is stored in the code. This is ok while developing the application. But runtime I want to use another connectionstring, both for security reasons and because each user of the application will correspond to a database user (SQL) and shall have a corresponding connectionstring. Is there an easy way to do this without having to restore to plain all datasets and do everything myself?

I have read through some other post and haven't been able to find an exact answer that I am looking for. I have a connection string saved in my.settings that I am using. My database is residing on a server. Now I am going to have to install this application at more then one area and they will have the database on their server. What I am wanting to do is for the application when it is loading to search the network to find the database and return the connection string without the user having to do anything. I know with a web application you can search the machine you are on for the connection string without knowing its location but was hoping there was some feature like that to search the network to find it.

I have a Windows application that uses typed datasets. When setting up the datasets, Visual Studio asks if you want to remember the connection.
Before filling the dataset, I programatically change the connection string of each table adapter so that it will connect to the remote database. Before this operation, it is set to the local database since that is the one I am developing on.[code]...

I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

I have a dataset that I created through the wizard, to pull the data and their types from the database tables and prevent some of the headaches of creating the tables and data types individually.I am looking for where the database connection for the dataset is defined at so I can change this. The reason being is I have added a database connection dialog where the user will select the location of the database server and I am wanting to pass the connection string from what the user selects to the dataset so the dataset uses this as its connection string instead of the default one I defined in the wizard.Where is this defined at so I can change it?

I am creating a VB windows form applications , the working can be summarized as users fills some form and data is saved in sql server database.Now the problem i am facing is that i have to deliver this as a setup file to someone, and that person will further distribute it to different users to run on their PC, what i am thinking is that the code once installed on other computers and executed will give errors because of the connection string of sql server db as it will not match with that computer . I know that if a distribute projects i can put connection string in app.config and every user can change it according to his/her machine .But as i am giving a setup file how to solve this problem

In my earlier project I was able to change the connection string during the app settings loaded event and it was successfully. When I try to do the same for a code library project, I am not getting the system.configuration.connectionstringsettings to work. Could you please tell if there is a work around for this, or else it is always better to write the sql code instead of depending on the adapters etc.
Additional information: Clients App is WPF with Vb. Database is SQL Server 2008 Code Lib would only be on server, slq connectiona and data retrieving and saving actions are stored in classes in code lib only. Code Lib would be used with WCF, wcf is used to share the classes only and classes have the data. WCF is hosted as a windows service on server used by NET.TCP
