I have written an application that is currently in use at my work. I am wanting to clean up the code and start preparing the application to make it available to other business of the same type. I want the user to be able to set the location of the access database at install. Is there a way to make the connection string a variable that is set by user at setup? Also what is the best installer to use I am currently using one-click.This is my next step as soon as I get the limit number of logins and some sort of licensing scheme.

I am developing a winform application which targets .NET Framework 4. I would like to get the connection string from the app.conf file but the Imports System.Configuration.ConfigurationManager fails. I can do a Imports System.Configuration but I cannot get to the .ConfigurationManager.
I have a small application where I am importing different versions (2008, 2010) of Excel sheets and saving them in SQL server. My program will find the 2008 versions but for some reason it will not find the Excel 2010 versions. I am not sure if my code for the Connection String is correct. Perhaps someone could have a look at my Connection String code?

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.
I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
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.
I am trying to connect DSN from my VB 2008 project. When i try using myoledb.connectionstring="DSN=myDNSname" I get the following error message An OLEDB provider was not specified in the connectionstring.
I've been all over the help files and finally patched together a VB OleDb connection string for delimited text files:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
"fName" is passed in by an open file dialog.In every case (for all paths) it throws: 'C:1_2010NormalFileNormal.csv' (or where ever it is pointed) is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.Since no path works, it must be a syntax error, but I'll be darned if I can see it.
Full code of this routine is:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited""" Dim conn As New OleDbConnection(connection)
I have written a program which connects to MS sql express 2008 using the string below. This is OK on my computer but when I try to run this on a client computer I get the following message: "An attempt to attatch an auto-named database for file :(C:UsersBarry2010 vb programsadotrialadotrialResults 6.mdf) failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
When it comes to database connections what is the difference between closing a connection & disposing a connection? I'm hoping to gain a more technical understanding of what happens when each is called & the effect on the database.
Why doesn't an exception get thrown when this function is called when there is no ConnectionString set for the Connection? I just spent 15 minutes debugging and staring at it and finally figured out it needed the connection string. Shouldn't an exception get thrown?

After using the following code, no errors are shown, but my database is not updated once i have made a change using my management system application.
Dim constring As String = Application.StartupPath.ToString() + "mydatabaseName.mdf" Public c As String = "Data Source=.SQLEXPRESS;AttachDbFilename=" + constring + ";Integrated Security=True;User Instance=True" Sub openConnection() conn.ConnectionString = c conn.Open() End Sub
I using SQL Server 2008 R2 to connect with HTML page. I trying to connect HTML page with login to SQL Database. I have try called the Source but didnt work.
I am developing a software which will connect to a SQL SERVER situated at Head Quarters over a VPN connection.But for times when VPN is disconnected I want my applications at the branches to connect to a local Sql Server installed at a local server.Now all the applications at each of the local machines have their connectionstring stored in their App.config file.When the VPN is disconnected we have to change each of the connection strings on all the applications in each machine. Is there a way to do it automatically switch the connection string depending on whether the Server is reachable or not, and to store the connectionstring at centralised location.
I'm trying to change my connection string to w/e the user wants. After a few tips here and there, this is what I've come up:
1: In my settings I've added - Name(login), Type(String), Scope(User), Value(Nothing)
2: Here is the code I'm using
Private Sub LoginForm1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Here I'm checking if the login in my.settings is there 'If not, I'm going to let the user choose what database
[code]....
The error I get is: Format of the initialization string does not conform to specification starting at index 0.here -
Dim con As New OleDbConnection(My.Settings.login)
When I have my con equal to when I added the datasource from it works.
i have the connection string cn = New OleDbConnection("Provider=Microsoft.Ace.OLEDB.12.0; Persist Security Info = False;" & _ "Data Source=C:printtest2.accdb;")which works fine but my database is in the server in a network what additional details do i need for the connection string The server name is as follows "Prntsvr-Test.auhbr.ctrixa.ad"how do i use the connection string
I have installed sql server 2005 in my machine which is installed vb.net 2008. I want my machine to distribute the database to the clients and make it as server.I don't have that much knowledge of how to overcome this issue as i am awfully naive about it.Let me start it here:I have got an application in vb.net...at first i was using ms access database 2007. then decided to switch on to the sql server since i want to distribute the database to the clients who are going to use my application.When i installed the sql server, i imported my access db files onto sql server database. i enabled tcp/ip as enable in the sql server network Configuration. i want use sql server windows authentication as my default user account of my system for the sake to simplify the issue.
Hence, i connected the sql server into the vb.net through the "add new data source".am done with that...the problem is how do i assign the connection string to the vb.net? Or how do i include a connection string in vb.net which tells every other computer that the database data source is in my computer so that every computer can automatically check it in the network.Where exactly shall i put the connection string...as far as my knowledge is concerned for access database, you can easily identify your connection string in project /properties/settings...it goes here and you put your database in any where.And what is the best connection string do i need for sql server 2005..computers are running windows xp.
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?
