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.
How do I assign a My.Settings.Item connection string to cmd.Connection connection string value?
Dim cmd As New SqlCommand() cmd.Connection = My.Settings.Item("csStaffHoursWorked") cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "spSaveDeltekImport"
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 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
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 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?
I used to work only with asp.net websites before. I know that in ASP.NET website, the connection string is found in the web.config file. My problem is now I have started working with VB.NET applications which needed to be interfaced to a database. How is a connection string created and where should I put it?
I want to create a client-server application, it means I just need 1 database on the server.I have a computer and a laptop. I set my laptop's IP to 192.168.1.1 and my computer's IP to 192.168.1.2.Now I place the database on my computer, the database name is db_transportasi.Problem is, how to connect my computer's database from my laptopSpecification :I'm using this string below for my connection :Data Source=ARVID-THEODORUSSQLEXPRESS;Initial Catalog=DB_TRANSPORTASI;Integrated Security=TrueI already setup my SQL Configuration Manager, enabled the TCP/IP, switch to the IP Addresses tab and set the IPAII Port Properties to 2301I turned off my firewall so I don't have to set any exceptionQuestion
I am trying to understand how a connection string obtains its value in a vb.net 2008 application. By stepping through code,I found that a connection string obtained its value from the following line of code:
By doing a search on the .net application, I found the Useall.Desktop.exe.config file in the bin/debug folder of the application.Thus I am wondering if the connection string information is initally obtained from the Useall.Desktop.exe.config file or would it obtain its inital values from an app.debug.config file?Would you explain the .net remoting and configuration manager interdependency to me? If they are separate items?

I have a VB.NET application that used LINQ To SQL. Right now, I am using a single server and it is working properly. My problem right now is that my application will be used in another branch and with another server. I have to make the application able to change the connection string according to their server IP
I have set the connection string of my dataset(typed) asData Source=MyHomeServerSQLEXPRESS;Initial Catalog=dbTestSharing;Integrated Security=TrueThis is going to be a client side application. I need to change the machinename in the connection string so it could connect with server.
Does anyone know how to store the connection string in a file rather than hard coding it in the application. For example i have declared this connection string in the form to connect to oracle database and it works. But i assume this is not the right way to go by if one is looking for more secured environment.
I got this Error Message while I try to preview the records in Dataset Designer:"The connection string could not be found or Data provider associated with the connection string could not be loaded"
You can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings Public WriteOnly Property RunTimeConnectionString() Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?
Ok I have a question about connection string in vb.net. Im using the string [Code] but here I am specifying the serverName by its name, now if I deploy my application and send it to another person to use it I see that server name is changing according to the name of the computer. Is there any way where by I can make my application to detect itself the Name of the server present in that computer and use it in connection string?
I have a little problem with application setting in VB.net 2008. I want to switch main server and backup server connection string with combobox. [Code] It did change the Application Setting connection string in the main form when combobox1 was changed. But the problem comes, when child form was called. On the child form there is DataGridView with Dataset using application connection string. Even the Backupserver was selected on the main form, child form dataset connection string doesn't change. I don't know how to pass the current connection string to child form dataset although it is set to use application setting.
I'm creating window application with VB.NET and flatfiles.the problem is how do i store the connection string in the app.config file that include the application.startup path?
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.
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 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
I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?
I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.
For the gist of the application:
In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.
I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.
Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim DBConnStr As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security
I'm facing a problem after installation any software setup that has a database in access(mdb file) How to I transfer file path in our connection string.
