Changing The Data Source For Connection String?
Mar 26, 2011
I developed a winform application and I want to send the .exe file to someone else. That means that my datasource for my connection string is not the same any more
Dim da As OleDbDataAdapter
Dim dt As New DataSet
Dim objConnection As OleDbConnection = New OleDb.OleDbConnection

How do I strip out the data source from the connection string so that I only have the directory path and file name.
My connection string is thus:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsMartinMy DocumentsVisual Studio 2008ProjectsRestelRestel IIRestel IIRestel.mdb

I am looking to make a data connection with a network server(sql server 2005). When I run the data source configuration wizard, it allows me only to pick a local database file. I want to use a connection string like this "Data Source=SQLSERVER;Initial Catalog=mydb;User Id=username;Password=password;" I know I can do that programmatically. But I would like to know whether I can do that using the data source wizard so that I will be able to use Bindingsources and tableadapters.

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.

We are going to change the connection string in Settings.vb so we don't need to worry about what it is when our app runs on a different computer other than the development computer.

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.

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 have two seperate databases, one is production the other is test. Before LINQ, I could simply change the connection string to swtich db's. However, the string is read only, and I have no way to change the string.
How can I change the Connection String programmatically?
Edited for Clarity
Im using my.settings to store all of this inforomation

I've created two forms of which two separate datasets/tableadapters were created by adding a datasource and dragging and dropping the fields onto my form.I was testing the program using a db that was located on my local drive. Well after publishing the app to the users machines, I noticed that the binded information was still being pulled from my local machine and not the database that the user is working off of.I've set the connection modifier properties for both tableadapters to Public, and I have written the following attempting to change the connection strings:
Private Sub btnSaveSettings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveSettings.Click
Dim pap As New frmPap
My.Settings.dbLocation = txtSettings.Text

I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

I have created a data source connection to an access db by using the wizard in vs2008. I have then used this as a data source for crystal reports. My user would like to put the database on a network and reference it there. Is there a way to set a new path for this data source during runtime?

My program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.

i have inherited some code form another developer who is using entityClient for a connection string. the web config entry looks like:
<add name="my_TESTEntities" connectionString="metadata=res://*/TEST.csdl|res://*/TEST.ssdl|res://*/TEST.msl;provider=System.Data.SqlClient;provider connection string="Data Source=myServer;Initial Catalog=TEST2;User ID=user_gg;Password=Aasdfasfasf;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient"/>
what are the metadata files? i found them in the debug folder of the code i was given, do i need to point to them? do i need to move them somewhere else?

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

I've always used this approach while implementing data layer DLL for web application:
1) put datasets into the dll project
2) use a helper class with a method like this:
public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub
3) when I need to use the dll I call a method like this (usually into global.asax):
xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")
This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

Cases is the table, OfferDate a field of the table wich is DateTime type.
When I use Between operator I get the following error :The expression contains unsupported operator 'Between'.
