Change Connect String Of Config File?
May 23, 2009
I have a file mdf. I can connect it on my machine by changing the code to connect string. But when i install another machine. Do i rechange connect string ? If so i have to install VBEXPRESS for them to modified the code.
Is there way when i give them software i can change server name on their machine.
i thought modify connect string of config file . But it seemed not yet.
<add name="QLBH2008ConnectionString"
connectionString="Data Source=COXUYEN.SQLEXPRESS;AttachDbFilename=|DataDirectory|mRIC.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"

I have created a VB application with some web references created at design time. The URL property of each is set to Dynamic which has created a string value in My.Settings and in the app.config file.
During testing and debug the application uses one set of web services and when live it needs to use a different set of web references with a different URL. I thought I'd be able to change the values for these URL's in the MyApplication.exe.config file once installed on the PC but the application still sees the URL which was used to create the web reference at design time.
I've searched forums and this should be the way it works but I can't understand why it isn't picking up the URL for the web service from the exe.config file once I have installed the application.

Im trying to make a program that works a bit like the log in on a computer. But i cant make it load a different .config file depending on what username is used. I want it to load a config file from different directories that match the username. eg if the username was bob then it could be: C:MyProgramLoginBobapp.config I've been teaching myself and this has had me stuck for ages.

I am just not happy with the fact that the user.config file gtets saved in the user's account folder. Is there a way to save it in the Application's Startup Folder instead? I couldn't find any configuration properties within the PROJECT PROPERTIES which would let me change the file location.

I have classes that get the connection string the the .config file through ConfigurationManager. They work great in the actual application. When I use them in a unit test with nUnit I recieve an 'Object referance not set to an instance of an object'. I also tried to see if nUnit would read a ConfigurationManager.AppSetting and it failed too. Is there a configuration or workaround for this?

I have a connection string in my database which I read throughout my VB .Net application. I have another string which is NOT a connection string though. It instead has information about a domain on LDAP. So LDAP string just needs to be stored in the web.config as a string, and also to be retrieved as a string.

I've been getting this error when I try and use my model container:
No connection string named 'PFModelContainer' could be found in the application config file.
I have my edmx file in a separate project. I checked the app.config file and my model was there, and I also put it in my main project app.config file. Still doesn't work. Here's the connection string:
<connectionStrings>
<add name="PFModelContainer"

I'm using vs2010 and can't get this to work. The same code has worked in earlier versions. What has changed?
config file:
<appSettings>
<add key="ConnectionString" value="Data Source=MikeLaptop;Initial Catalog=AdventureWorksDW2008R2;Integrated Security=True"/>
</appSettings>
Code:
Dim strProvider As String = ConfigurationManager.AppSettings("ConnectionString")
strProvider is always = nothing
How to do this now?

I have a question about the App.Config file. My understanding is that the connection string is stored within this file. I have setup my application so that the App.Config file is not only written to c:users<username>appdatalocal but also to c:users<username>appdataoaming. I plan to encrypt the connection string, my question at this point is will it encrypt the connection string in ALL copies of the App.Config file? It looks like at this point that the App.Config file is stored in two places on the hard drive.

The application sits on a virtual environment and when I remote in and run the application, it connects to the remote database. However, when I remote in with a service account and double click the same .exe, it tries to connect to the local host database and ignores the app.config. The code is the same, only the login name I use is different. The login I use is part of the local admin group. Any ideas?

I have application scoped settings set within my application's project properties that are working fine, but I would prefer not to have these settings hardcoded within the progarm.My goal is to modify these settings during application install, by reading from a file located with the setup MSI file.I have an insaller class successfully running and reading values from a file that I wish to change the application settings to. Unfortunatley, I am unable to figure out how to access these application scoped settings.
* I attempted writing directly to the app.conf file, but only ended up with an appsettings section as opposed to updating the specific application settings I was after
Dim targetDir As String = Context.Parameters("targetdir")
Dim templatedir As String = Context.Parameters("templatedir")
Dim savedir As String = Context.Parameters("savedir")
Dim exePath As String = String.Format("{0}myAppName.exe", targetDir)
[code]....
From within my Installer class, how best do a directly change these 2 applicationsettings?After searching / reading many posts and MSDN Class definitons, I am not able to figure it out.

I have been reading/researching/taking advice on connecting to my db by storing the connection string in my app.config. I have the connection string named "MyDB" in my app.config file. However, I cannot figure out how to use it in my code. I use mySQL. I added the configuration.dll reference. How do I pull the connection string from the app.config file and open a connection with it?

I have a connection string (which works fine) to connect to AD through my web application in my web.config. Traditionally, however, I've created a new connection to pull info. from the user after login like so:
Using adDirectory as New DirectoryEntry("LDAP://OU=myou,DC=mydc,DC=dc,DC=com")
Dim adTicketID as String = ticket.Name
myVar = "adDirectory.Children.Find("CN=" & adTicketID).Properties("myproperty").Value
End Using
It seems that I should instead use the connection from the web.config like so:
Using ADCS as New DirectoryEntry
Dim adTicketID as String = ticket.Name
myVar = "adDirectory.Children.Find("CN=" & adTicketID).Properties("myproperty").Value
End Using
Is this possible? How would I accomplish it so that I don't need to constantly create new directoryentries?

It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.

I need to know what is the common way to store a SQL server connection string for an application in VB.NET.How do I read app.config values How to do it in ASP How do I store a connectionstring (unencrypted thus unsafe)It's quite frustrating not to find a decent and full answer on how to store a connection string in VB.NET in app.config (or settings.settings if it's better) safely. At the moment it's hardcoded and so it is immobile and in plain text.
