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 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.

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 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 been working on a Printer INK Management Program for my Company. We have many different districts we deal with. Each district has a different Server.I am trying to create the application where they can place the database file anywhere they would like on the server and when they first run the application it would ask them to choose the location of where they placed the file.I would like to know how i would be able to edit the connection string information in the app.config file during run time.

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 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.

Dim dbconn As OleDbConnection
Dim DBCommand As OleDbDataAdapter
Dim DS As New DataSet
dbconn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:COLORsitedataCUFORHDR.dbf;Extended Properties=dBASE IV;")
[Code]...
I prefer SQL server but im afraid in this app I have no choice. I think the .DBF file is v III dBase according to a thrid party .dbf viewer. The code explodes on the DBCommand.Fill(DS) line, telling me I have provided and invalid file path. The path is good to go.
Should I be using a driver with a different provider? When I remove the Extended Properties parameter I get an error unrecognizable database format - hinting in this case the path is correct.

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 sent the application exe to a user to test and they get an unhandled exception error and the details show my personal My Documents Folder/DEBUG path from the project. So I tried to use Application.ExecutablePath but when I release that it points to "My Documents" Folder (not the debug) folder. The file to open is in the same folder as the exe is in but for some reason the error occurs because the application is not looking for the file using the path where the EXE was launched from. Here is my code that relates to the section giving my users a problem:
from the module
Public Class shrd
Public Shared ocSess As cSession
[code]....
How can I get the application to open the file that is in the same folder as the exe when the user launches

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?

I know this topic has been addressed a million times but please help me out. I have read so many articles on HOW TO encrypt and decrypt the app.config file but I need to know WHEN and WHERE I should encrypt it.
The problem arose because we found an AppName.exe.config file on a users computer and the database username and password was clearly visible. I understand that the .config file gets created during the VB app install process and is used
by the application. I then learned about the aspnet_regiis.exe tool and ran it on the app.config file inside my VB project. I am guessing that was the wrong thing to do.
When I now install the app on user desktops, it gives an error stating failed to decrypt the connection string. Also, when one of my other developers attempts to open the project in his copy of visual studio on his computer, he receives an error when trying to access the setting portion of the project properties. We store all of our projects on a file server and any developer can access the projects via a mapped drive on their computer.
So how am I supposed to encrypt the .config file. If I can't encrypt the App.config file in the development environment, then I'm guessing I have to perform the encryption on the users PC during the install process? How do I do that? Or is that what I am supposed to do?
Just for reference, here is the aspnet_regiis command I ran.
aspnet_regiis.exe -pef "connectionStrings" S:ProjectsDevelopmentVB.netPTPUSourceCodePTPU -prov "DataProtectionConfigurationProvider"
One last thing, maybe it's my misunderstanding of the issue but if this problem has existed since .Net 2.0, why has an option not been built into the development studio to encrypt connection strings?. This would seem to be a very common issue, even their own dataset wizard creates connection strings that are clearly readable.

I have tested my code in a windows form project and it works great. so now I want it to run as a service.The problem i have is referring to "name" in my configuration string which is in app.config.
Dim settings As ConnectionStringSettings = _
ConfigurationManager.ConnectionStrings(Name)
(Name) is under-squiggled and message name is not declared, file IO functionality is available in the microsoft.visualbasic namespace.
