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"
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"
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'm not very good at deployment and I'm facing a problem: First Off, I'm using Vista. i have created a windows application in vb.net which has a database file named Customerdb.mdf in it. I have selected the database and in the property, I have selected Embedded Resource option. I have used the following connection:
I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" [Code] ..... I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored.
I have a query that is working fine on my local but when placed on the server it comes back with this error,
Server Error in 'Page' Application.

On my development PC I have SQL Server installed, and my SQL connetion works perfect. I use a trusted connection. But on other PCs, where the program should work later, there is only a SQL "Express" installed (by another application), and it seems they have an password on the SQL Server (I guess). I have no chance to get the password from the other application. My connection is not working here. I created some connection test, but it does not seem to work with the trusted connection. I need the SQL only for creating my own database and connecting to my own database. So how do I create a connection with SQL Express for creating and working with my own database?
Here my code for testing the connection so far (Fehler means Error, erfolgreich means Success) Private Sub mnu_Verbindung_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnu_Verbindung.Click Dim bolFehler As Boolean = False Dim sServer, sDatab As String [Code] .....
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?
Friend Function GetValues(ByVal TableName As String, ByVal FieldName As String) As DataTable Dim cn As New SqlConnection Dim cmd As New SqlCommand[code].....
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 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
