IDE :: Missing Connection Strings In Application Settings
Nov 11, 2010
I am using VB 2008 & MS Access 2007 Databases for my Windows Forms Applications.The Problem is my Connection strings have been disappeared from DataSource Configuration Wizards & now i am unable to edit any Connection String in DataSet Designer.I had tried to create a Macro in MS Access Data File but didn't know how to create & so desided not to save any & just quit from Access and came back to Visual studio. Since then only this prob. has started. Earlier to this everything was just fine.I have tried to uninstall MS Office as well as Visual Studio then Re-installed Visual Studio but the problem is still there.
1] Error while trying to Reconfigure Data Adapter in Dataset
2] Disappeared options & Empty Connection Combo Box
3] Add Connection DialogBox with no DataSource property line in the Grid control

I've came to the stage where i need to save strings and application settings for my application. The My.Settings have worked it out until now. Now i have to store so many settings it's hard to keep track of them. That is why i need something new. So i've been looking around in INI files which seems impressively simple - but not very flexible. I've also took a look at XML which seems to be something to dive in to. But what i need now is advice. How do you store settings?

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.

I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.

Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.

i have created a user setting named 'setmeup' as string, scope = user, value = "magical meow meow!".in my code i access it and assign it a new value like this...my.settings.setmeup = "howdy cowboy!"my.settings.save()application.restart()when the application restarts, i expect the my.settings.setmeup = "howdy cowboy!" but when i check its contents its still "magical meow meow!".but when i use application.exit() instead of application.restart() and manually restart the program, my.settings.setmeup = "howdy cowboy!" which is correct.what must i do? i want to use application.restart() because i don't want the users to double-click the icon again to start the program. i want the program to restart automatically.

I am storing some user settings by the very handy My.Settings classes in VB.net and it seems to be taking a mixed case string (a file path and filename) and returns it in all upper case.

I have several programs I have written for my music studio/production company. Many dealing with inventory, customer DB etc. All of my programs are in VB6 and I have started to convert them all to VB.NET. I am getting proficient with VB.NET and connecting to DB using the very simple and generic connection strings, Example:
dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
dbSource = "Data Source = C:/develop/Customer Tracking/resource.mdb"
con.ConnectionString = dbProvider & dbSource
[Code]....
As you can see I am using a basic MSAccess DB and I want to get away from this and start using SQLExpress,
connect to a standard SQLExpress DB? (when I loaded SQLExpress I took the defaults...)

What is a dynamic MS Office Connection string? I have realized that each each version of MS Access has a unique Connection String. Now my concern is that if I use MS Access 2007, for example, it may haave compatibility/connection problems if an application is deployed in a machine with a different edition of MS Access. Is my understanding correct? If so, how to go around this hiccup?

I'm creating a program in VB.Net that heavily interacts with 2 large MSSQL databases. I do not know a ton of vb and I'm fairly new, but I would assume just having the connection strings in the code and releasing the program it would be quite easy for someone to reverse the program and get my connection info? correct me if I'm wrong. My question is I'm wondering if there is a safer way to use a connection string in my program. Would I just have to encrypt my app? Create a module or dll?

It seems the code below for user ID and password is not used by my application, but I'm kinda confused at how my application is able to connect to the SQL server with only servername and dbname, because even if I remove the entry in the app.config for user ID and password, the application is still able to connect and return a data set. Can anyone explain how this happens?

I have read and worked through all of the examples in the book "ADO.NET 2.O", but there is so much there with so many ways to handle data, I am having difficulty translating the examples into my own real life application. I am confused about creating runtime connection strings, connection strings in my app.config file, connection strings in the properties for a sql connection control, etc.
I have a midichildform with a datagridview control, and I use a table adapter to edit and update the SQL Server 2005 Express edition database. There is no problem there. However, I also have a button control that I want to use to "process" the data that has been updated with the table adapter. I want to open the updated table, read each record on at a time, manipulate the data and add a records to another table. Do I have to create a connection string and an oleDBconnection? Or can I somehow use the connection string that is in my app.config file? [Code]

I need a bit of advice. I would like to store secure connection strings somewhere safe in vb.net. How can I build the secure connection strings in what situation and what would be the best?
As I have done the little research and found that the secure connection strings would be encrypted the strings and input the strings in app.config, so I would have to make a change in the app.config[code]...

I have been struggling with the construction of an Access connection string. Here's the problem.My Visual Basic 2008 project is located in a disk partition on my hard drive that I have named S:. My Access MDB file is in the same location.When I deploy the application it obviously will not be in an S: drive on the user's machine. My concern is that if I construct the Connection String using the file designations on my computer as:
(Provider =Microsoft.Jet.OLEDB.4.0; Data Source =S:MyApplicationmydatabase.mdb; User Id =admin; Password =
The deployed application won't know where to look for the data file. I know there are some shortcuts that will allow me to construct the connection string, but I do not know either the designated names or where to find them.

I have two executables that access a DLL containing Data Access Layer objects Each exe can have a different config containing info on server and database name, connection string etc.How do I pass the config info to the DAL objects?
Obviously I can pass the config strings to the DAL objects every time I instanciate one, but that seems messy and repetitive as every class in the DAL will require Properties for the Config strings..if there is a way for the instanciated DAL objects to read some properties from the calling object without me having to pass them explicitly?

We decided to use the registry for handling our deployment with connection strings in our VB.net application.
The requirements are:
If the program cannot connect to the server, first check the registry for a connection string. IF not, create the folder and fill in the name, type, and data. Make sure its encrypted.
I have never edited or created anything in the registry.

I've just started ASP.NET for real, and I was wondering if it is possible to use connection strings from Data Sources instead of hard-coding them. I've added my connection in Data Sources and it works, and I can also drag a table to a page in design mode, but I can't figure out how to access it in code. Here's what I get when I drag it in:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
EmptyDataText="There are no data records to display.">[code].....

In the past I've used a Singleton Pattern to load the connection string when the application starts via the global.asa file.
I have a project now where each user has a unique connection string to the database. I would like to load this connection string once. The issue is that the singleton pattern will not work for me since each user has there own connection string. Basically the connection string is created dynamically.
I do not want to store it is session. If anyway has a clever way of doing this in .NET let me know ?

from [url] they write this:
This example includes a password to demonstrate how DbConnectionStringBuilder works with connection strings. In your applications, we recommend that you use Windows Authentication. If you must use a password, do not include a hard-coded password in your application.but if we do not hard-code the password then does it mean that we are supposed to retrieve the password from some other place? so is it correct to say that we should save the password in a file and then retrieve it when the app runs?

I have a situation where I have a vb.net program that uses two connection strings. This program will be used on multiple web servers on multiple domains and the only difference for any of them is the two connection strings.What would be the best solution to read in these connection strings from a file separate from my actual .vb code?
Ideally I want to be able to drop the .vb and the connection string file into its own folder on any number of asp.net websites and not update anything else (for example add any connections to the web.config or anything) than the external file containing the connection strings, I assume something like xml would suffice?

As I have done the little research and found that the secure connection strings would be encrypted the strings and input the strings in app.config, so I would have to make a change in the app.config
To change from this unprotected app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
[Code]....
The code have been built to a guy who known as Nick J. Fessel. I am not too sure if it very secure to use it so. Do anyone know that if the connection strings is secure or not?
info for the secure connection strings without being found out

I get this error
Format of the initialization string does not conform to specification starting at index 34.
When I take my connection string and store it in the project settings. I know that this works.
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb
Because if I use it like this
Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb")
conn.Open()
The connection succeeds but if I try this
Dim conn As New OleDbConnection(My.Settings.Default.employeeConnection)
conn.Open()
I get that error.
name:employeeConnection
type:string
scope:application
value:Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Employees.accdb
