Invalid Connection String When Using Table Adapter?

Jan 17, 2011

I'm trying to use variables in my connection string to a table adapter. The only clean cut method I've seen is the following, however, I'm getting "Invalid Connection string" upon run-time. I'm assuming maybe this can't be done?

Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'BCPM_DDBODataSet.LTC_FBS' table. You can move, or remove it, as needed.
LTC_FBSTableAdapter.Connection.ConnectionString = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security Info=True;User ID={0};Password={1};Default Database=bcpm_ddbo;Session Mode=ANSI;"
Me.LTC_FBSTableAdapter.Fill(Me.BCPM_DDBODataSet.LTC_FBS)

Change Table Adapter Connection String ?

Oct 8, 2008

I have a Windows application that uses typed datasets. When setting up the datasets, Visual Studio asks if you want to remember the connection.

Before filling the dataset, I programatically change the connection string of each table adapter so that it will connect to the remote database. Before this operation, it is set to the local database since that is the one I am developing on.[code]...

Modify Connection String In Table Adapter?

Jan 14, 2011

Is this possible? Currently I'm using a login form that passes txt box values to string and then use as variables in the hand coded connection string (for each query) is there a way to use this with a table adapter? something similar to how access remembers your login credentials when accessing an ODBC table? I've tried editing the connection string in the config file, but says it's invalid every time. I'm only using the table adapter to populate my form after running a hand coded search query.

This is what i use for manual insert/update/delete query

Private sConStrFormat As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security Info=True;User ID={0};Password={1};Default Database=bcpm_ddbo;Session Mode=ANSI;"

Table Adapter Connection Timeout?

Jun 18, 2012

connectionString="Data Source=########;Initial Catalog=DowntimeD51;Persist Security Info=True;User ID=#######;Password=########;Connection Timeout=120;Encrypt=False;TrustServerCertificate=False;Network Library=dbmssocn" I have the above connection string in a vb windows application , This is part of my app config file.

I then have a number of table adapters for connecting my business logic to the database , One of the queries inparticular is a pretty large one and requires extra time to complete however the connection is getting a timeout error. When I checked the adapter connection with Dim connection2 As Int32 = Adapter1.Connection.ConnectionTimeout This shows the connection time out to be 120 seconds but the timeout is still occuring after 30 seconds.

Invalid Connection String When Modifying Tableadapter Connection?

Jan 19, 2011

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

VS 2008 - Apparently Invalid Connection String

Mar 20, 2009

Before I explain, the connection string I am trying to use is copied directly from elsewhere in the application that has always worked and still does.
Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=|DataDirectory|cdb.rmd;
Persist Security Info=False;

My problem is that no matter if I go to "Server Explorer", "Data Sources", or any other option it will not let me add a datasource/database. Up to this point I have done everything at runtime but now due to reporting issues I need to create a dataset in design view.

This is what happens:
I click "Add connection..."
I choose "Microsoft Access Database File" (Which it is...)
I click "Continue"
Form shows up with a field for my connection string, which I insert (shown above).
I click "Ok"

I get the following error:
Format of the initialization string does not conform to specification starting at index 0.
The "Test Connection" button is apparently useless as the connection passes even if the field is blank.

I have attempted reducing the connection string to only what is absolutely necessary.
I have copied the string directly from connectionstrings.com replacing my filename.
I have renamed the file to an .mdb extension.
I have used the full path from C: all the way to the file.

VS 2008 .DBF Connection String - Invalid File Path?

Sep 21, 2009

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.

Refresh Table Adapter When I Have A Child Table Attached With Parent Table?

Dec 21, 2011

I have a data table whose one column is related to a column of another table.

The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause.

VS 2008 - Store The Connection String In A Settings Table In The Database?

Apr 20, 2010

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?

Get Id Value With Table Adapter?

May 29, 2010

To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?
